    Interview with Ty Beal - The Highlights and Lowlights of the Dietary Guidelines

    Most people are told to eat less, count calories, and “try harder.” But what if that advice is the real reason so many people struggle with weight and health? In this broadcast, we dive deep into why controlling hunger matters more than counting calories, and how your body’s hormones—not willpower—play the biggest role in fat loss and metabolic health. You’ll learn: ● Why calorie restriction often backfires ● How hunger is driven by hormones like insulin ● Why feeling hungry all the time is NOT your fault ● What actually helps you eat less without suffering ● How a metabolic approach changes long-term results This conversation is especially helpful if you’ve tried diets before and felt stuck, frustrated, or blamed yourself for “not being disciplined enough.” The goal here isn’t quick fixes. It’s understanding your body—so results finally make sense. 👇 Join the conversation Have you ever felt hungry even while dieting or eating “healthy”?

    Fasting and Weight Loss - Solving the Two-Compartment problem

    Why intermittent Fasting is a simple solution for weight loss. Body fat is simply a method of storing food energy. When we eat, our body wants to store those calories. When we don't eat (intermittent fasting), our body uses those calories. So, if we want to lose body fat, increase the duration of time that we are not eating.

    Controlling the 'Body Fat Thermostat'

    Are you struggling to lose weight despite eating less and exercising more? It’s time to stop blaming your willpower and start understanding your biology. Dr. Jason Fung, best-selling author of The Obesity Code, explains the revolutionary concept of the "Body Fat Thermostat." Just like your home’s AC maintains a specific temperature, your body has a "set point" for how much fat it wants to carry. If you only focus on "Calories In vs. Calories Out" without addressing your hormones, your body will fight back by increasing your hunger and slowing down your metabolism. This is why most diets fail in the long run! In this video, we dive deep into: ✅ The Science of Homeostasis: Why your body resists weight change. ✅ Hormones vs. Calories: The real role of Insulin, Cortisol, and GLP-1 in fat storage. ✅ The "Big Lie" of Dieting: Why eating fewer calories can sometimes lead to more fat storage. ✅ Resetting the Set Point: Practical insights on how to naturally lower your body's fat thermostat. ✅ Homeostatic Hunger: How to control your appetite by choosing the right foods. Weight loss isn't just about math; it's about hormonal balance. Whether you're interested in intermittent fasting, low-carb living, or simply improving your metabolic health, this deep dive will change the way you look at your body. Recommended Books by Dr. Jason Fung: 📖 The Hunger Code 📖 The Obesity Code 📖 The Diabetes Code 💬 WE WANT TO HEAR FROM YOU! Have you ever experienced the "rebound" effect after a diet?

    The Real Cause of Weight Gain (It's NOT Willpower)

    Learn more about Ancestral Supplements: Code: FUNG Link: https://ancestralsupplements.com/FUNG (Disclosure: This video was sponsored by Ancestral Supplements. Note that I use this brand personally at this moment because I believe in a whole food supplement) Most people still believe weight gain is simply about calories. But if calorie restriction alone worked long-term, why do so many people struggle? In this conversation, Dr. Jason Fung sits down with Julia from Ancestral Supplements to explore the hormonal model of weight gain, insulin, ultra-processed foods, and how modern eating patterns may influence metabolism. Topics discussed: • Why “calories in, calories out” may be incomplete • Insulin as a key metabolic hormone • How processed foods can affect hunger and satiety • The difference between whole foods and refined foods • Understanding insulin sensitivity • The role of nutrient density in traditional diets Weight regulation is complex and involves more than simple math. This discussion explores how hormones, food quality, and dietary patterns may play a role.

    The Real Reason You Can't Lose Weight (Hormones and Obesity - a Masterclass)

    Have you been told that losing weight is simply about "eating less and moving more"? For decades, the "Calories In, Calories Out" model has been the gold standard for weight loss. But what if it is completely wrong? In this Masterclass, I break down the real reason you can't lose weight: Hormones. We dive deep into the science of obesity and explore why calorie counting fails 99% of the time, as proven by massive studies like the Women's Health Initiative. Weight gain is not a character flaw or a lack of willpower—it is a hormonal imbalance. We will discuss exactly how hormones like Insulin, Cortisol, Thyroid, and Testosterone control your body fat, and more importantly, how you can fix it. In this video, you will learn: ● �� Why the 'Eat Less, Move More' advice is scientifically flawed. ● �� How hormones dictate whether your body stores or burns fat. ● �� The truth about weight-loss drugs like Ozempic (GLP-1). ● �� Why the 1977 dietary guidelines triggered the obesity epidemic. ● ✅ The ultimate, natural solution to lower insulin and lose weight effortlessly. � Join the Conversation: Have you struggled with calorie-counting diets in the past?

    The Obesity Epidemic, Explained

    Dr. Jason Fung explains how the 1977 dietary guidelines led to the obesity epidemic. The Dietary Guidelines for Americans changed the way Americans ate, advising us to eat more carbs and less fat to prevent heart disease, but this lead to weight gain. When we gained weight, we were then told it was our own fault.

    A Calorie Deficit cannot EVER exist – here’s why!

    Most people are told that “weight loss = calorie deficit.” But the truth is, a calorie deficit is a myth. Your body is not a simple calculator where you just subtract calories and lose fat. In this video, Dr. Jason Fung explains the science behind why focusing only on calories fails, and why hormones, insulin, and fat metabolism are the real keys to healthy and lasting weight loss. When people try extreme dieting or drug-induced appetite suppression, they often experience side effects like the dreaded “Ozempic face” — hollow cheeks, sagging skin, and an unhealthy look. This happens because subcutaneous fat (the fat under the skin) gets burned instead of visceral fat (the dangerous fat around your organs). The result: you may lose weight, but you don’t look or feel healthy. Fasting works completely differently. Instead of just cutting calories, fasting changes your hormones and metabolism: �� Insulin drops, allowing fat burning to start �� Growth hormone rises, protecting muscle and skin elasticity �� Autophagy activates, repairing tissues and preventing loose skin �� Visceral fat is targeted, which improves health and appearance �� Brown fat (through beiging) is activated, boosting metabolism naturally That’s why people who fast look healthier, stronger, and younger compared to those who follow harsh calorie-restricted diets. In this video you’ll discover: ✅ Why calorie restriction almost always fails ✅ The science of subcutaneous vs. visceral fat ✅ How fasting avoids the “Ozempic face” problem ✅ The role of hormones in fat burning and aging ✅ How fasting improves skin health, prevents sagging, and supports long-term fat loss �� If you’re serious about losing weight without losing your health or youthfu look, this video is a must-watch. �� Subscribe now for more science-backed videos on fasting, weight loss, an metabolic health.

In this video, Dr. Jason Fung breaks down the latest science and practical tips to help women fast in sync with their hormones. Whether menstruating, perimenopausal, or postmenopausal — this video will help you optimize your health and fat loss. What You'll Learn in This Video: - How estrogen & progesterone affect hunger and metabolism - Why fasting feels easier before ovulation - The ideal time to do longer fasts or intermittent fasting - How menopause changes fat burning vs. sugar burning - Why many women gain weight during perimenopause - Practical tips to adapt your diet through different phases of your cycle - Personalizing your fasting strategy using your hormone patterns Science-Backed + Practical Advice During the first half of your cycle (follicular phase), rising estrogen can suppress appetite and increase your body’s ability to burn fat. This makes it the best time to fast — your cravings are low and your metabolism is geared for fat-burning. After ovulation, progesterone increases appetite and shifts your metabolism toward storing fat, making it a better time to focus on low-carb eating instead of long fasts. In menopause, estrogen levels drop, appetite increases, and your bod starts burning more glucose than fat. This metabolic shift makes weight gain easier and fat loss harder — but it’s manageable with the right fasting strategies.

    Type 2 Diabetes isn't Genetic ... It's Caused by THIS

    Are you struggling to understand the real root cause of Type 2 Diabetes? For decades, the medical community has focused on insulin resistance without clearly explaining what actually causes the cells to become resistant in the first place. In this comprehensive masterclass, we break down the science of insulin resistance and reveal why the outdated 'Lock and Key' (internal starvation) theory fails to explain the modern obesity and diabetes epidemics. Instead, we explore the 'Overflow Paradigm'. You will discover how decades of high-carbohydrate diets have literally overstuffed your cells with glucose, leading to hyperinsulinemia, fatty liver, and metabolic syndrome. More importantly, Type 2 Diabetes is a fully reversible condition. By understanding how your body processes sugar, you can take control of your metabolic health using simple, evidence-based methods like low-carb diets and intermittent fasting. In this video, you will learn: ✅ The Root Cause: Why Type 2 Diabetes is actually a disease of too much insulin (hyperinsulinemia). ✅ The Suitcase Analogy: Why your cells are rejecting insulin because they are already jam-packed with glucose. ✅ The 1977 Disaster: How the dietary guidelines to "eat more carbs and less fat" directly sparked the obesity and diabetes epidemics. ✅ Reversing the Disease: How low-carbohydrate diets and intermittent fasting empty the cells of toxic glucose. ✅Modern Medicine: How treatments like GLP-1 agonists (Ozempic) and SGLT2 inhibitors fit into the reversal process. �� Join the Conversation: Have you tried a low-carb diet or intermittent fasting to manage your blood sugar?

    Why Do We Get Fat? Part 2 - It's the Insulin, stupid!

    Pre-order The Hunger Code at www.doctorjasonfung.com. Check out hunger management tools at www.drinkaeira.com Stop counting calories. If 'Calories In, Calories Out' really worked, why do those diets fail 99% of the time? In this video, Dr. Jason Fung explains why obesity is not a caloric imbalance, but a hormonal imbalance—specifically involving insulin. Most people believe that weight gain is a personal choice caused by eating too much and exercising too little. But science tells a different story. Discover how your body's internal thermostat (BMR) actually regulates your weight and why lowering insulin, not calories, is the key to long-term fat loss. In this video you will learn: ● Why the 'Calories In, Calories Out' model is scientifically flawed. ● How damage to the hypothalamus leads to massive weight gain (independent of willpower). ● The role of Basal Metabolic Rate (BMR) in energy expenditure. ● How Insulin acts as a 'Fat Storage Hormone' and blocks lipolysis (fat burning). ● Why simply eating less lowers your metabolism and makes you regain weight. medical Disclaimer: The content of this video is for educational purposes only and is not intended to be a substitute for professional medical advice, diagnosis, or treatment.
