Dr. Gabrielle Lyon doesn’t mince words when it comes to entrepreneur health.
In a recent episode of the Big Deal Podcast, the New York Times bestselling author and longevity expert sat down with host Cody Sanchez to deliver some hard truths about performance, brain health, and the non-negotiables of building a body that can keep up with ambition.
And her opening statement? There’s no such thing as a healthy sedentary person.
For high performers who think they can outwork their biology, Dr. Lyon has news: your success has a ceiling, and it’s set by your health.

Muscle Is the Organ of Longevity
Dr. Lyon’s entire philosophy centers on one often-overlooked system: skeletal muscle.
Unlike organs you can’t control—like your thyroid—muscle is the only organ system you have voluntary power over. And according to Dr. Lyon, it’s the foundation of everything from metabolic health to cognitive function.
Muscle is the organ of longevity. It is an organ system that we have taken for granted forever.
She explained that muscle acts as the sink for metabolism—the place where your body processes glucose and manages energy. When muscle health declines, so does brain function, sexual health, and even your risk for Alzheimer’s.
In fact, Alzheimer’s is now being called type three diabetes of the brain. The healthier your muscle, the healthier your brain.
The Entrepreneur’s Health Trap
Sanchez asked the question every busy founder wrestles with: Why is it so hard to prioritize health when we know it matters?
Dr. Lyon didn’t let her off easy.
I cannot believe that you are not getting your 10,000 steps. I think that we have to have a major intervention.
She pointed out that 74% of Americans aren’t meeting baseline exercise recommendations—150 minutes of movement per week and two days of resistance training. Entrepreneurs, despite their ability to suffer through business challenges, often can’t commit to 100 push-ups.
The disconnect? Chronic stress versus acute stress.
Entrepreneurs are marathoners in business but struggle with the acute physical demands of a hard workout. They’ve also habit-stacked around work, not wellness, making it difficult to see the direct line between a training session and their bank account.
The Three Non-Negotiables for High Performers
Dr. Lyon laid out a simple, actionable plan for anyone serious about performing at their peak.
Step One: Resistance Training (3 Days a Week)
This is the cornerstone. Lifting weights isn’t optional if you want to protect your brain, maintain metabolic health, and stay functional as you age.
Step Two: High-Intensity Interval Training (1–2 Days a Week)
Just 20 minutes of sprint intervals—one minute on, one minute off—can improve brain speed and cardiovascular health.
If you want to be a good entrepreneur, then you have to have the physical skills in place, which is resistance training.
Step Three: Move More
Walking meetings. Standing desks. Pushing your kids on sleds. Whatever it takes to avoid prolonged sitting.
Because sedentary behavior doesn’t just fail to help—it actively harms. Your muscle transitions from looking like a filet to a wagyu steak: marbled with fat, weak, and metabolically broken.
Sexual Health, Muscle, and Erections
In one of the episode’s most attention-grabbing moments, Dr. Lyon dropped a stat that made both hosts pause.
By age 40, 40% of men experience erectile dysfunction. By 50, that number jumps to 50%.
The solution? Lift heavy and do cardio.
The more healthy muscle mass you have, the greater sexual function you have.
She explained that muscle health directly impacts vascular function—the plumbing that makes erections possible. And if men aren’t using that muscle regularly, they can literally lose up to a centimeter of length over time due to reduced blood flow.
Use it or lose it isn’t just a saying. It’s biology.
Brain Health Starts With Body Health
Dr. Lyon made it clear: the fatter you are, the smaller your brain volume.
The more overweight you are, the wider your waistline, the lower the brain volume. Fatter you are, dumber you are.
It’s a blunt statement, but the science backs it up. Obesity, insulin resistance, and sedentary behavior all shrink brain volume and increase Alzheimer’s risk.
On the flip side, cardiovascular exercise and resistance training protect against brain atrophy, especially during hormonal transitions like menopause.
Nutrition Hacks for Busy Entrepreneurs
Dr. Lion’s nutrition advice is refreshingly simple.
Start every day with 30 grams of protein within the first hour of waking. This could be:
- A whey or plant-based protein shake
- Greek yogurt with fruit
- Six eggs
- Steak and eggs
- A chicken patty or salmon
This single habit stabilizes blood sugar, reduces cravings, and augments willpower throughout the day.
If you prioritize your diet well, then you’re not chasing these ebbs and flows of blood sugar.
She also recommended aiming for around 100 grams of protein daily—split between two meals if needed—and reducing processed carbs unless you’re actively training.
The average American eats around 300 grams of carbs per day. The recommendation? 130 grams. Anything above that must be earned through exercise.
Three Budget-Friendly Health Hacks
If money and time are tight, Dr. Lyon offered three essentials:
- Get a treadmill desk (under $100 on Amazon)
- Buy a kettlebell or resistance band
- Prep a protein shake and have it ready every morning
No gym membership required. No complicated meal plans. Just consistency.
Sleep, Circadian Rhythm, and Morning Sunlight
Good sleep doesn’t start at night—it starts in the morning.
Dr. Lyon emphasized the importance of consistent sleep and wake times, and getting outside first thing to anchor your circadian rhythm.
If you anchor your morning, it sets up your night.
Sunlight exposure—without glasses or contacts—triggers melatonin regulation and improves sleep quality hours later. It also supports muscle protein synthesis, which is suppressed during sleep deprivation.
For those struggling with middle-of-the-night waking, she suggested a mixed meal before bed—protein plus carbs—to prevent reactive hypoglycemia around 3 or 4 a.m.
PCOS, Fertility, and the Power of Muscle
One of the most surprising revelations? Muscle health directly impacts female fertility.
Dr. Lyon cited research from Dr. Melanie Cree, a leading PCOS expert, who found that it’s not body fat percentage that matters most—it’s intramuscular adipose tissue, or fat stored inside the muscle.
Exercise and a good diet will often improve people’s likelihood of conceiving.
This is something most doctors don’t tell patients. But for women with PCOS—the leading cause of infertility in young women—resistance training and proper nutrition can be game-changing.
Loneliness, AI, and Human Connection
Dr. Lyon touched on emerging research linking loneliness to dementia risk.
Humans are social creatures, and real relationships—complete with physical touch and nonverbal cues—release oxytocin, the bonding hormone that supports mood and brain health.
Parasocial relationships and AI bots don’t cut it. While they may feel similar, they lack the physiological benefits of in-person connection.
Sanchez shared a personal story about her grandparents: one side stayed socially active and sharp into their 100s. The other became isolated during COVID and rapidly declined into dementia.
Inverse Thinking: The Recipe for Misery
At the end of the episode, Sanchez asked Dr. Lyon to use inverse thinking: What’s the guaranteed way to be as unhealthy as possible?
Her answer was disturbingly simple:
- Don’t exercise. Walk less than 3,000 steps a day.
- Eat a high-calorie, high-carb, processed food diet.
- Don’t have any friends.
- Bonus: Get hammered every night.
Guaranteed my recipe for misery.
The Playbook You Actually Need
Dr. Lyon’s new book, The Forever Strong Playbook, is designed for people who don’t want fluff—they want a manual.
It includes exactly how to train, what to eat, how to think, and how to recover. No workbook exercises. Just evidence-based action steps.
If you have a body, this book is for you.
It’s available on Amazon and wherever books are sold—complete with 60 recipes and workout protocols built for real life.
Final Takeaway: You Can’t Outpace Your Biology
Dr. Gabrielle Lyon’s message is consistent, evidence-based, and unapologetic.
Entrepreneurs can tolerate financial risk, emotional chaos, and brutal schedules—but they can’t outrun poor health. And the fix isn’t complicated: lift weights, eat protein, move daily, sleep consistently, and show up for real human connection.
Because as she reminded Sanchez—and all of us—there’s a massive gap between knowing what to do and actually doing it.
Motivation won’t come. Discipline has to.
