Belly fat isn’t a character flaw.
It’s a message from your body telling you something important.
Dr. Mindy Pelz, a New York Times best-selling author and functional medicine expert, has spent years helping millions of people unlock their metabolic health through strategic fasting.
In a recent conversation, she revealed why your body stores stubborn visceral fat around your organs—and exactly how to reverse it without counting a single calorie.

Your Body Isn’t Broken—It’s Protecting You
When you look in the mirror and see extra belly weight, your first instinct might be self-blame. But according to Dr. Pelz, that couldn’t be further from the truth.
Your body is saying, ‘Hey, I have extra glucose. I have extra hormones. I have extra toxins and I don’t know what to do with it. So instead of putting it around your heart, your lungs, your liver, I’m going to put it around your belly to save your life.’
Belly fat is your body’s storage solution for things it can’t process—synthetic estrogens from beauty products, ultraprocessed food ingredients, and imbalanced hormones.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Instead of vilifying yourself, start asking: What has my body been trying to eliminate?
Stop Counting Everything
Women especially have been conditioned to measure everything—calories, macros, clothing sizes, scale numbers. Dr. Pelz believes this obsession disconnects us from our own bodies.
We have brought so much of our head to the diet game and we forgot to bring our body into the picture. Your body will tell you when it needs something and when it doesn’t.
Learning to read hunger signals and reconnect with your natural rhythms is more powerful than any macro calculation.
Men Lose Weight Faster—Here’s Why
If you’re a woman fasting alongside a male partner, prepare for some frustration. Men typically drop weight much faster.
Dr. Pelz explains this with a musical analogy: women are like violins—complex, with many hormonal “notes” to play. Men are like kazoos—simple, with just one note.
Men have a four or five-piece symphony hormonally. Women have a 100-piece symphony.
Weight loss is fundamentally a hormonal issue, and women’s hormonal complexity requires more nuanced strategies.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The Insulin-Belly Fat Connection
Starting around age 35, women begin losing estrogen. This hormonal shift makes you increasingly insulin resistant over the next 10 to 15 years.
Foods that didn’t cause weight gain at 30 suddenly pack on pounds at 45. Estrogen used to distribute fat evenly across your body, but as it declines, fat migrates to your midsection.
For men, belly fat typically signals toxic overload—especially synthetic estrogens from sources like beer, which can create aromatase and disrupt hormonal balance.
Cortisol Storage Around Your Middle
Cortisol is designed to make you move. When stress hits, you’re supposed to physically respond—run from the metaphorical tiger.
But if you don’t move when cortisol spikes, your body stores it as belly fat.
If we don’t move with cortisol, it’s going to get stored because it needs to be used and if it’s not used, it will be stored.
This is why Dr. Pelz recommends morning exercise—ideally within the first hour of waking, after your coffee when cortisol naturally rises.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
White Fat vs. Brown Fat
Not all fat is created equal. White fat is stubborn and hard to burn. Brown fat contains more mitochondria and burns more easily as energy.
The key to losing belly fat? Converting white fat into brown fat.
Mechanisms that accomplish this include:
- Cold plunges – just a few minutes can trigger the conversion
- Fasting – transforms hard-to-burn fat into usable energy
The Olive Oil Hack
Here’s a simple strategy: two tablespoons of olive oil daily for 30 days has been shown to specifically target visceral fat.
That olive oil really helps burn that belly fat.
The mechanism involves balancing your omega-3 to omega-6 fatty acid ratio. Ultraprocessed foods flood your body with inflammatory omega-6 oils, which your body stores around your midsection.
Ideally, you want a 1:1 ratio of omega-6 to omega-3. Most people eating processed foods have a ratio closer to 20:1.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Adding olive oil (or sardines, wild salmon, grass-fed beef) raises your omega-3 levels, correcting the imbalance and signaling your body to release stored belly fat.
Six Fasting Methods Explained
Intermittent Fasting (12-17 Hours)
Between 12 and 15 hours without food, your body metabolically shifts from glucose burning to fat burning. You’ll start producing ketones and growth hormone—the fountain of youth hormone that declines after age 30.
At 17 hours, autophagy kicks in—your body’s cellular cleanup mechanism that repairs and rejuvenates cells.
The 24-Hour Fast
At 24 hours, your gut undergoes remarkable repair. Your body eliminates harmful bacteria, candida, and other problematic microbes while upregulating stem cell production.
I had so many supplements to help my patients with gut repair. The minute I discovered the power of the 24-hour fast, I literally stopped all my supplement sales for gut.
The 36-Hour Fast
This is the sweet spot for burning visceral fat—the dangerous fat around your organs and belly.
Your body aggressively searches for stored glucose and begins breaking down stubborn white fat for energy. Most people will achieve both autophagy and consistent ketone production in this window.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The 48-Hour Fast
At 48 hours, something remarkable happens: your entire dopamine system reboots.
Your brain creates new dopamine receptor sites, which can reduce food cravings and improve mental health long after the fast ends. People report that simple pleasures—like watching a sunset—feel more meaningful again.
The 72-Hour (3-Day) Water Fast
At 72 hours, your immune system repairs itself and stem cell production surges. Stem cells travel throughout your body, healing damaged tissues.
Dr. Pelz shares a personal story: she healed a chronic Achilles tendon injury with a five-day water fast, allowing two full days of stem cell activity.
On the fifth day the pain went away and I’m not joking that was about 10 years ago. The pain has never come back again.
Carnivore Fasting
This combines 17 hours of fasting (triggering autophagy) with eating only meat during your eating window.
Meat doesn’t contain plant toxins like lectins and oxalates, which can trigger immune responses in sensitive individuals. This approach stimulates T-regulatory cells that balance your immune system.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Five days of carnivore fasting helped them lose more weight than even a 3-day water fast.
Carnivore fasting is particularly powerful for people with autoimmune conditions, gut issues like SIBO, or stubborn inflammation.
What You Can Have During a Fast
Strict water-only fasting replicates research conditions, but sustainability matters more than perfection.
Dr. Pelz approves these during fasts:
- Black coffee – stimulates autophagy
- Coffee with cream – individual response varies; use a continuous glucose monitor to test
- MCT oil – helps burn fat, reduces hunger, boosts ketones
- Mineral salts (sodium, potassium, magnesium) – prevents heart palpitations and hair loss
- Olives – pure fat, no protein, keeps you in ketosis
- Fasted snacks – under 400 calories and under 20 grams protein
The Number One Morning Hack
Want to double your fat burn? Get sunlight within the first hour of waking.
Morning red and orange light signals your body that daytime has begun. This turns off melatonin production and wakes up your pancreas, making you more insulin sensitive.
If you want to lose weight, do not eat in the dark. Melatonin makes you insulin resistant.
Dr. Pelz recommends a slow morning warmup: sit by a window, watch the sunrise, drink coffee slowly, and don’t touch your phone for the first hour.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
This gentle rhythm prepares every hormone in your body for optimal function throughout the day.
Vitamin D and Fat Storage
Vitamin D is actually a pro-hormone that helps produce every hormone in your body. But here’s the catch: it’s fat-soluble, which means it gets stored in fat tissue.
The more body fat you carry, the more vitamin D gets trapped in fat cells instead of being available for hormone production.
Get adequate sun exposure or supplement with vitamin D to support healthy hormonal function and metabolic health.
What to Eat in Your Eating Window
Forget complicated macro calculations. Dr. Pelz recommends eating whole foods from nature—foods without ingredient labels.
Think farmers market produce, grass-fed meat, wild fish, eggs, and healthy fats. Carbohydrates should come from sweet potatoes, regular potatoes, and occasionally rice.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Avoid ultraprocessed foods loaded with inflammatory seed oils: canola, vegetable, safflower, sunflower, soybean, and partially hydrogenated oils.
The Protein Principle
Instead of obsessing over total daily protein, focus on protein pacing: 30 grams of protein per meal.
Recent research shows that combining protein pacing with 15-hour intermittent fasting is one of the most effective weight loss strategies.
Start your meal planning with protein—eggs, grass-fed sausage, wild game like venison or bison, salmon—then add vegetables and healthy fats.
The Detox Signals Your Body Sends
Dr. Pelz teaches her patients two simple self-assessments during fasting:
The Armpit Test: Is it a pit or a puff? If it’s puffy, that indicates stagnant lymph. Use salt scrubs or dry brushing to move toxins out through this portal near breast tissue.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Tongue Color: White, yellow, or even black coating on your tongue during a fast indicates fungus dying off and leaving your body through your mouth.
Look at your tongue when you’re fasting. If it’s white, if it’s yellow, I’ve seen black tongues. That’s fungus dying off.
The Biggest Fasting Mistake
You fast for 15 hours, feel accomplished, then break your fast with ultraprocessed junk food.
This immediately throws off your omega-3 to omega-6 balance, triggering your body to store more belly fat.
The solution: Break your fast with whole foods—fermented foods, bone broth, clean proteins, and healthy fats that nourish rather than inflame.
Final Takeaway
Belly fat isn’t a punishment for poor willpower. It’s biological feedback showing you where your body is struggling—with insulin resistance, hormonal imbalance, toxic overload, or chronic stress.
Dr. Pelz’s approach offers a framework that respects your body’s sophisticated design, particularly for women navigating complex hormonal transitions.

Start small: compress your eating window, get morning sunlight, add two tablespoons of olive oil daily, and focus on whole foods with adequate protein.
Your body isn’t broken. It’s brilliantly protecting you. Now you know how to work with it instead of against it.
