How Many Hours of Fasting Do You REALLY Need to Burn Visceral Fat | Dr. William Li

How long should you really fast—and can fasting for too long actually harm your health? In this in-depth lecture, Dr. William Li, world-renowned physician and scientist, explains the real science behind fasting, insulin regulation, visceral fat, metabolism, and hormonal balance. Many people assume that longer fasts automatically lead to better fat loss and health benefits—but biology doesn’t work that way. Dr. Li breaks down what actually happens inside your body at different fasting lengths, why insulin—not calories—controls fat burning, and how metabolic health determines whether fasting helps or hurts you. You’ll learn the difference between short daily fasts and longer fasts, who should avoid extended fasting, and how to choose a fasting window that matches your physiology. This video is essential viewing if you’re practicing intermittent fasting, considering longer fasts, or struggling with stubborn belly fat, insulin resistance, or fatigue. 👉 Watch till the end to understand how to fast smart, not extreme. ⏱️ Time Stamps (with Emojis) ⏰ 00:00 – Introduction: The fasting confusion 🧠 01:12 – Why fasting isn’t about calories 🧪 03:05 – Insulin: the real switch for fat burning 🔥 05:20 – What happens at 12–16 hours of fasting ⚠️ 07:45 – Why short fasts may not burn visceral fat 🔄 10:10 – 18–24 hours: the metabolic shift 🧬 12:55 – Ketones, brain fuel, and hunger control 🧹 15:05 – Autophagy explained simply ❌ 17:10 – Can fasting too long backfire? 🩺 19:05 – Who should NOT do long fasts ✅ 21:05 – Choosing the right fasting window 🏁 22:30 – Final takeaways & practical advice intermittent fasting, fasting too long, how long should you fast, Dr William Li fasting, visceral fat loss, insulin resistance, fasting and insulin, autophagy fasting, metabolic health, fat burning hormones, time restricted eating, fasting benefits and risks, fasting science, belly fat fasting, insulin sensitivity, ketones fasting, growth hormone fasting, fasting mistakes, healthy fasting duration, fasting for longevity #IntermittentFasting #DrWilliamLi #FastingScience #VisceralFat #InsulinResistance #MetabolicHealth #HealthyFasting #Autophagy #FatLossJourney #HormoneHealth #Ketosis #TimeRestrictedEating #LongevityHealth #FatBurning #BellyFat #WellnessEducation #HealthOptimization #FastingMistakes #MedicalScience #Biohacking 📚 References Li, W.
