Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Vitamin D3 + K2: The Seasonal Essential

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

When Seam uploaded his latest bloodwork results, the calculator revealed something extraordinary.

My biological age with the Brior’s age was 10.2.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

Biological age testing uses blood markers to estimate how fast someone is aging compared to their chronological age. The more advanced version, called Brior’s age, analyzes 22 blood markers including kidney function, liver enzymes, immune cells, blood sugar, lipids, and inflammation.

When Seam uploaded his latest bloodwork results, the calculator revealed something extraordinary.

My biological age with the Brior’s age was 10.2.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

The Shocking Biological Age Discovery

Biological age testing uses blood markers to estimate how fast someone is aging compared to their chronological age. The more advanced version, called Brior’s age, analyzes 22 blood markers including kidney function, liver enzymes, immune cells, blood sugar, lipids, and inflammation.

When Seam uploaded his latest bloodwork results, the calculator revealed something extraordinary.

My biological age with the Brior’s age was 10.2.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

His secret? Focusing on fundamental health pillars rather than extreme biohacking.

In a recent interview, longevity researcher Seam explained exactly how he outperforms one of the world’s most dedicated biohackers without the obsessive lifestyle.

The Shocking Biological Age Discovery

Biological age testing uses blood markers to estimate how fast someone is aging compared to their chronological age. The more advanced version, called Brior’s age, analyzes 22 blood markers including kidney function, liver enzymes, immune cells, blood sugar, lipids, and inflammation.

When Seam uploaded his latest bloodwork results, the calculator revealed something extraordinary.

My biological age with the Brior’s age was 10.2.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

While tech millionaire Brian Johnson spends millions annually on longevity protocols and takes hundreds of supplements daily, this researcher maintains superior biomarkers with a remarkably simple, accessible approach.

His secret? Focusing on fundamental health pillars rather than extreme biohacking.

In a recent interview, longevity researcher Seam explained exactly how he outperforms one of the world’s most dedicated biohackers without the obsessive lifestyle.

The Shocking Biological Age Discovery

Biological age testing uses blood markers to estimate how fast someone is aging compared to their chronological age. The more advanced version, called Brior’s age, analyzes 22 blood markers including kidney function, liver enzymes, immune cells, blood sugar, lipids, and inflammation.

When Seam uploaded his latest bloodwork results, the calculator revealed something extraordinary.

My biological age with the Brior’s age was 10.2.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

His approach prioritizes balance across all systems rather than optimizing single markers to extreme levels. A powerlifter might have exceptional muscle strength but poor metabolic health. An ultra-lean athlete might have great body composition but compromised hormones.

The key insight: It’s better to have all biomarkers in good range than to have some elite markers and others suffering.

The Most Important Biomarkers to Track

Rather than obsessing over 100 different measurements, Seam focuses on markers that provide maximum insight into overall health and mortality risk.

VO2 Max: The Cardiovascular Foundation

High aerobic capacity correlates with lower body fat, reduced visceral fat, better blood sugar control, and decreased inflammation. Targeting 50 or above provides a solid baseline, with higher values offering additional benefits.

People who exercise regularly naturally improve multiple biomarkers simultaneously, making VO2 max an excellent proxy for overall metabolic health.

Visceral Fat: The Hidden Health Destroyer

Visceral fat surrounding organs acts as an endocrine organ, influencing inflammation, immune function, and metabolic health. Seam maintains just 54 grams of visceral fat—possibly too low, as he acknowledges there’s no data on such extreme leanness.

The average 30-year-old carries around 500 grams, increasing to nearly 1,000 grams by age 60. Research shows excess visceral fat poses significantly greater health risks for men than women, with linear increases in mortality risk above 15% body fat for males.

Pull-Ups: The Bodyweight Litmus Test

Bodyweight exercises reveal the crucial relationship between strength and body composition. Someone might deadlift 200 kilograms but struggle with three pull-ups—a sign of excess body weight relative to functional strength.

Elite pull-up standards by age (males):

• Ages 20-40: 15-20 strict pull-ups
• Ages 40+: 10 pull-ups
• Age 60: 7 pull-ups
• Age 80: 2-3 pull-ups

Seam completes his age in pull-ups each birthday—33 strict, dead-hang repetitions at age 31, with full lockout each time.

I’m actually progressing faster than my chronological age.

High-Sensitivity C-Reactive Protein: The Inflammation Indicator

Chronic inflammation drives nearly all hallmarks of aging and increases risk for every chronic disease. hs-CRP provides a reliable measurement of systemic inflammation.

Optimal range: As close to zero as possible, ideally under 0.1 mg/L. Values above 1.0 mg/L indicate problematic low-grade systemic inflammation.

High visceral fat, poor metabolic health, and reduced insulin sensitivity all elevate hs-CRP levels.

Hemoglobin A1C: The Blood Sugar Snapshot

This marker reveals average blood sugar levels over three months, providing insight into metabolic health. Pre-diabetes begins at 5.8%, while the average non-diabetic person measures around 5.5%.

Target range: Below 5.2%, ideally around 4.8%

However, HbA1c doesn’t tell the complete story. Someone following a very low-carb diet might show slightly elevated values due to gluconeogenesis (liver glucose production) while maintaining excellent insulin sensitivity.

Fasting Insulin: The Metabolic Health Cornerstone

Low fasting insulin indicates efficient glucose metabolism without insulin resistance. Seam’s fasting insulin measures 2.2-3.0 micro units per liter.

Optimal range: Less than 8-10 micro units per liter, with values under 7 being ideal.

Triglycerides: The Fat-Burning Barometer

Low triglycerides signal that your body efficiently burns fat for fuel and can flexibly switch between fat and carbohydrate metabolism. High triglycerides often precede insulin resistance, impairing insulin production before blood sugar rises.

Seam maintains triglycerides at 35 mg/dL, with a previous low of 15 mg/dL. Optimal range: Less than 50 mg/dL, though below 100 mg/dL is acceptable. Values above 100 mg/dL suggest metabolic dysfunction.

The Body Composition Sweet Spot

Physical fitness and lean body mass form the foundation of Seam’s approach. People who exercise consistently naturally optimize multiple biomarkers simultaneously.

For males, research shows anything above 15% body fat associates with linear increases in mortality and heart disease risk. The optimal range appears to be 10-12% body fat—lean enough for metabolic benefits without hormonal compromise.

Going too lean creates problems. When Seam dropped below 10%, his testosterone declined and SHBG (sex hormone binding globulin) increased, reducing free testosterone availability.

Interestingly, his latest test showing biological age of 10 came when he carried more body fat than previous tests, after optimizing other dietary and exercise factors.

The Mediterranean-Style Diet That Works

Seam’s diet follows Mediterranean principles—but not the pasta-heavy cuisine many imagine. His approach emphasizes whole foods while avoiding ultra-processed options.

Daily food choices include:

• Vegetables: Broccoli, cauliflower, carrots, leafy greens
• Fruits and berries: Blueberries and seasonal options
• Protein sources: Salmon, cod, sardines, ground beef, eggs
• Dairy: Cottage cheese, kefir, yogurt, curd
• Carbohydrates: Potatoes, sweet potatoes, sourdough bread, rye bread
• Fats: Olive oil (moderate amounts), pumpkin seeds, pistachios

He consciously avoids ultra-processed foods entirely, recognizing they provide fewer nutrients per calorie while being less satiating—a recipe for overconsumption and nutrient deficiency.

The Macro Balance

Seam maintains moderate protein intake at 1.4-1.6 grams per kilogram bodyweight (approximately 120-135 grams daily). This contradicts popular fitness advice recommending 2+ grams per kilogram.

Too much protein, it’s just not necessary for muscle growth and muscle strength, and you’re sacrificing other macronutrients. You’re sacrificing the fats and carbohydrates that could actually give you energy.

His fat intake remains relatively low, sourced primarily from whole foods rather than added oils. This leaves room for moderate to high carbohydrate intake with emphasis on fiber—the opposite of many longevity-focused ketogenic approaches.

High-fiber carbohydrates from potatoes, sweet potatoes, berries, and vegetables provide sustained energy without the metabolic drawbacks of refined carbs.

Calorie Management Without Obsession

Seam doesn’t count calories or measure macros. Instead, he adjusts intake based on performance, energy levels, and mirror feedback.

Before bloodwork testing, he implements a slight calorie deficit, as caloric restriction temporarily improves numerous biomarkers. However, he doesn’t maintain aggressive deficits year-round, recognizing the importance of adequate nutrition for strength development and VO2 max improvement.

His intuitive approach: Eat more on training days, less on rest days. If abs become less defined, reduce intake slightly. If strength declines or energy drops, increase food.

The Minimalist Supplement Stack

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.

A 31-year-old health optimization expert has achieved what seems impossible: ranking number one on Brian Johnson’s Rejuvenation Olympics leaderboard with a biological age of just 10 years old.

While tech millionaire Brian Johnson spends millions annually on longevity protocols and takes hundreds of supplements daily, this researcher maintains superior biomarkers with a remarkably simple, accessible approach.

His secret? Focusing on fundamental health pillars rather than extreme biohacking.

In a recent interview, longevity researcher Seam explained exactly how he outperforms one of the world’s most dedicated biohackers without the obsessive lifestyle.

The Shocking Biological Age Discovery

Biological age testing uses blood markers to estimate how fast someone is aging compared to their chronological age. The more advanced version, called Brior’s age, analyzes 22 blood markers including kidney function, liver enzymes, immune cells, blood sugar, lipids, and inflammation.

When Seam uploaded his latest bloodwork results, the calculator revealed something extraordinary.

My biological age with the Brior’s age was 10.2.

That represents a 22-year delta between his chronological age of 31.5 and his biological markers. His blood values resemble those of a 10-year-old child.

This doesn’t mean he looks 10 years old, but rather that his organ systems function with the efficiency of someone decades younger.

Why Simple Beats Complex

Seam’s philosophy differs dramatically from extreme biohacking approaches. He stopped testing expensive epigenetic age markers two years ago, finding them less useful than comprehensive blood panels.

I’ve shifted more towards focusing on the blood markers and other biomarker based tests which are a lot cheaper. They are more specific in terms of pinpointing which exact organ system needs more attention.

Unlike protocols requiring 200+ daily pills, Seam takes just six to seven supplements—chosen for cost-effectiveness and evidence-based benefits.

Glycine: The Longevity Amino Acid

Glycine consistently extends lifespan in animal studies by 3-5%, primarily by balancing methionine—an amino acid abundant in animal protein that accelerates aging in excess.

Modern diets provide excessive methionine with insufficient glycine, creating an imbalance that may shorten lifespan. Glycine also lowers body temperature to improve sleep, reduces blood sugar, and decreases glycation for better skin health.

Omega-3 Fatty Acids: The Inflammation Fighter

Large cohort studies consistently show people with higher blood omega-3 levels (above 8% omega-3 index) experience lower rates of heart disease, Alzheimer’s, and all-cause mortality.

Japanese populations average 8-12% omega-3 index, while Americans and Europeans typically measure around 4-5%. The target: at least 6.5%, optimally above 8%.

Astaxanthin: The Skin Protector

This powerful carotenoid from salmon, shrimp, and seaweed protects skin against UV damage, reducing wrinkles and accelerated skin aging from sun exposure. While skin appearance doesn’t directly impact lifespan, UV protection preserves tissue integrity.

Lutein and Zeaxanthin: The Eye Defenders

Found in blueberries, egg yolks, and dark leafy greens, these carotenoids protect eyes from screen-induced fatigue and blue light damage. Maintaining eye health preserves the connection between retina and brain, protecting the suprachiasmatic nucleus—the body’s master circadian clock.

Since circadian dysfunction accelerates aging, preserving eye health theoretically maintains better metabolic rhythms, hormone regulation, and body temperature control.

Vitamin D3 + K2: The Seasonal Essential

During winter months or when testing shows deficiency, Seam supplements vitamin D with K2 to prevent excessive calcification. Optimal vitamin D levels support immune function, hormone production, inflammation control, and overall health.

However, he emphasizes that supplements can’t replicate all benefits of actual sunlight exposure.

Methylated B Vitamins: The Homocysteine Manager

Seam uses B vitamins periodically if homocysteine levels rise, indicating poor methylation. He doesn’t take them continuously—only when bloodwork shows elevated values.

The Longevity Escape Velocity Theory

Seam’s interest in extreme health optimization stems from a concept called longevity escape velocity, popularized by Aubrey de Grey. The theory predicts that around 2040-2045, medical advances will reach a tipping point where life expectancy increases faster than we age.

Each year, new treatments would extend lifespan more than one year, allowing people to “catch the wave” of successive breakthroughs—potentially living decades or centuries longer.

If you reach 2045, you can live like 100 years more.

However, Seam remains pragmatic about the likelihood. He estimates just a 5% probability of achieving longevity escape velocity by 2045, noting that the last major life-extension breakthrough—caloric restriction extending mouse lifespan 65%—occurred 40 years ago.

This realistic assessment shapes his balanced approach. Living like a monk for 20 years to potentially gain centuries makes sense if the probability is high. But with only 5% likelihood, extreme sacrifice seems unwarranted.

The Genetics Reality Check

Perhaps most importantly, Seam emphasizes genetic limitations that many longevity enthusiasts ignore. Research by Dr. Ruri Alon suggests genetics determines approximately 50% of maximum lifespan, with 25% from lifestyle and 25% from random factors.

Even perfect lifestyle optimization—zero heart disease, Alzheimer’s, kidney disease, or cancer—would only increase average life expectancy by 5-10 years.

Even if you follow everything perfectly, you sacrifice a lot, you’re very neurotic or stressed about it, then you might only live like five years longer than the other person.

This sobering reality informs his philosophy: optimize health, but don’t sacrifice quality of life in pursuit of marginal longevity gains.

Living to 120+ will require technologies that don’t yet exist—gene therapies, organ regeneration, comprehensive early screening, and rejuvenation treatments. A healthy diet alone won’t get humans to 150 or 160 years.

The Hidden Truth About Modern Health

Contrary to social media narratives claiming unprecedented health crises, Seam argues this is actually the best time in history to be healthy.

Yes, absolute numbers of people with diabetes, heart disease, and Alzheimer’s have increased. But when adjusted for population size and age, mortality rates for these conditions have plummeted.

Cancer survival rates now reach 60-70%, compared to 10-20% fifty years ago. Heart disease mortality peaked in the 1970s and has since declined 70-80%. Age-adjusted death rates for diabetes and Alzheimer’s continue falling.

More people develop these conditions because populations have doubled and average lifespans increased 10-20 years—but fewer people die from them thanks to medical advances and preventive care.

This trend accelerates annually. Seam predicts that within 10-20 years, almost nobody will die from heart disease or cancer due to continued improvements in treatment and prevention.

The Balanced Path Forward

Seam’s approach demonstrates that elite biomarkers don’t require extreme sacrifice or obsessive protocols. His principles distill to refreshingly simple guidelines:

• Maintain 10-12% body fat through intuitive eating and regular activity
• Prioritize whole foods in Mediterranean style with adequate protein, moderate fats, and high-fiber carbs
• Perform bodyweight exercises that balance strength with leanness
• Develop strong VO2 max through consistent cardiovascular training
• Take strategic supplements addressing specific deficiencies rather than every marketed product
• Test comprehensive blood panels to identify which systems need attention
• Balance optimization with life quality, avoiding neurotic perfectionism

Perhaps most valuable is his perspective on tradeoffs. Perfect health practices might extend life 5-10 years—meaningful, but not worth decades of misery or social isolation.

The goal isn’t just adding years to life, but adding life to years—maintaining function, vitality, and enjoyment throughout a longer health span.

His biological age of 10 while maintaining a relaxed, sustainable lifestyle proves that simple fundamentals consistently applied outperform complex protocols inconsistently followed.

In an age of biohacking extremism, Seam’s approach offers something revolutionary: evidence-based moderation that actually works.
