Summary
Dr. Jason Fung presents a compelling case for fasting as a more effective method for weight loss compared to traditional calorie counting. He shares the success story of a client named Eduardo, who, after adopting a fasting regimen, lost nearly 70 pounds and reversed his diabetes. Eduardo's journey began when he was diagnosed as pre-diabetic and later required medication. After watching one of Fung's videos, he decided to try fasting, which ultimately led to significant health improvements.
Fung explains that the common belief that reducing calorie intake directly leads to weight loss is flawed. He illustrates that when individuals cut calories, their bodies often adjust by lowering their metabolic rate, resulting in no net weight loss. Instead, he emphasizes the importance of fasting, which allows insulin levels to drop and enables the body to utilize stored fat for energy. By extending fasting periods, individuals can effectively tap into their fat reserves.
Eduardo's fasting approach included 40-hour fasts every three days and, after achieving his weight loss goal, he transitioned to shorter 24-hour fasts for maintenance. Fung advises those interested in fasting to educate themselves on potential side effects and changes in their bodies, encouraging them to seek resources and community support to navigate their fasting journey safely.
Show Notes
Why intermittent fasting is much more effective for weight loss than simple calorie restriction. Fasting allows insulin to fall which allows the body to use its stores of body fat for energy, where simple cutting of calories may or may not do so. Just cutting calories does not fix the hormonal changes of obesity.

I’m sharing my personal experience with the fasting mimicking diet (FMD). I’ll break down how it works, the science behind it, and whether it’s worth trying.I’ve been talking about fasting since 2014, but one of the few researchers exploringfasting at the time was Dr. Longo in California. He discovered that fasting triggersbeneficial repair processes in the body, but fasting for five days can be tough. That’swhere the fasting mimicking diet comes in — it allows you to eat small amounts ofspecially designed foods while still keeping your body in a fasting state.�� What You’ll Learn in This Video:✅ How the fasting mimicking diet works and the science behind it✅ Why lowering nutrient sensors like insulin and mTOR matters for health✅ Health benefits shown in studies on weight loss, diabetes, cancer, and more✅ My personal experience – what worked, what didn’t, and how it felt✅ Pros: Structured, easier than water fasting, good taste, and convenient✅ Cons: It's pricey, but it replaces five days of mealsI’ve done water fasts before, and they’re not easy — especially on days 3 and 4. Butthe FMD made it much more manageable since you’re still eating a bit of food. Plus,it’s less stressful and more socially convenient when eating with family.I’ll also walk you through exactly what’s included in the FMD kit — from soups andbars to teas and vitamins — and share my thoughts on the taste and overallexperience.If you’re curious about fasting or looking for an easier way to experience the benefitsof fasting, this video is for you!�� Watch now and let me know your thoughts in the comments!▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▶️ Timestamps/Chapters00:00 – Intro00:20 – Fasting Mimicking Diet01:27 – How can a 5 day fast be made easier?03:38 – Why Mimic Fasting?

Fasting, Muscle Loss and Protein Needs - the facts | Jason Fung💪 Does fasting burn muscle? Absolutely not! This video explains why fasting doesn’t lead to muscle loss and dives into how the body uses energy from stored fat and glucose rather than breaking down muscle. Dr. Jason Fung discusses the science behind muscle preservation during fasting, the role of protein, and how muscle growth is actually tied to exercise, not just protein intake.Topics Covered:How fasting impacts muscle massWhy protein intake is important but often overestimatedUnderstanding muscle strength and energy during fastingStudies on fasting and muscle strength improvement 🧪Key Takeaways: 1️⃣ Fasting primarily uses fat and glucose, sparing muscle tissue2️⃣ Muscular strength remains stable, even during long fasts3️⃣ Overeating protein doesn’t necessarily build more muscle; exercise is essential 💪4️⃣ Fasting may even improve heart muscle health after a heart attack ❤️Watch to learn more about the fascinating link between fasting and muscle health.
