Why Fasting for Fat Loss and Performance Works Better Than Dieting
If you want to drop body fat, sharpen your mind, recover faster, and regain control over cravings, look no further than fasting for fat loss and performance.
This isn’t about skipping meals or starving yourself. Fasting is a biological tool hardwired into your DNA, backed by our most trusted mentors—Chaffee, Saladino, Baker—and supported by the rhythms of our primal ancestors.
💡 What the Experts Say About Fasting for Fat Loss and Performance
🧠 Dr. Anthony Chaffee
“Fasting combined with a carnivore diet is like hitting the reset button for your metabolism. It’s the fastest way to lower inflammation and burn fat while preserving muscle.”
Chaffee advocates fasting as a complement to zero-carb eating—especially for those healing from autoimmune issues or metabolic disease.
🥭 Dr. Paul Saladino
“Fasting is a useful tool, but should be used wisely. Too much can backfire, especially for lean, active people.”
Saladino supports strategic intermittent fasting (16:8 or OMAD) while also emphasizing the role of carbs (fruit/honey) for those with high activity levels or thyroid concerns.
💪 Dr. Shawn Baker
“You don’t need six meals a day. You need one big meal with real food and a reason to train hard.”
Baker is a fan of OMAD (one meal a day), using fasting to improve body composition, energy, and mental sharpness. His clients often thrive with just steak and salt.
🦣 Primal Bod & Evolutionary View
Fasting was never optional for our ancestors. There were days without food. The strongest humans adapted to it.
“Fasting for fat loss and performance reflects how we evolved: feast hard, fast naturally, and thrive with less.”
🧭 H2: How to Use Fasting for Fat Loss and Performance Based on Your Body Fat %
Use the protocols below to personalize your fasting strategy.
Goal | Body Fat % | Fasting Protocol | Frequency | Electrolytes Required? | Best Way to Break Fast |
🔥 Burn Fat (Lean Body) | <15% | 16:8 IF | 4–6x/week | Yes (Salt + Mg) | Steak, eggs, liver |
🧼 Gut Reset | 15–25% | 18:6 or OMAD | 3–5x/week | Yes | Fatty meat, organs |
💥 Metabolic Reset | 25–35% | 24–36hr Fasts | 1–2x/week | Absolutely | Salt water → meat & eggs |
🧨 Obesity/Pre-diabetic | 35%+ | 48hr Extended Fast (1–2x/mo) | Monthly w/ care | Mandatory | Salt/electrolytes → eggs + steak |
🧂 Do You Need Electrolytes During Fasting?
Yes—especially when fasting for fat loss and performance. Fasting depletes sodium, potassium, and magnesium. Without these, you’ll crash or feel miserable.
Sodium: 3–5g/day during fasts
Magnesium: 300–500mg (glycinate or citrate)
Potassium: Use “Lite Salt” or potassium chloride (1–2g)
Avoid sweetened electrolyte drinks. They’ll spike insulin and defeat the purpose.
🥘 What Should You Eat to Break a Fast?
Let’s get real. Our ancestors didn’t sip bone broth after a fast—they crushed meat off the bone.
But if you’re coming off a 24+ hour fast, some people do better with a “gentle” transition:
Ideal Sequence:
Optional: Bone broth or salt water (to ease digestion)
30–60 mins later: Steak, eggs, liver, suet
Avoid: High-carb or sugary foods (this spikes insulin and can cause bloat, headaches, or rebound hunger)
💡 Note: For shorter fasts (16–18hrs), go straight to the steak.
