The Body Fat Thermostat - How it Works | Jason Fung

Why does muscle matter so much—not just for strength, but for fat loss,insulin sensitivity, metabolism, and long-term health?In this in-depth conversation, Dr. Jason Fung sits down with Dr. Gabrielle Lyonto explore why muscle is one of the most misunderstood—and mostimportant—organs in the human body.

Dr. Jason Fungadds crucial insight into how insulin, fasting, and metabolic health intersect withmuscle preservation—especially for people struggling with stubborn weight gain.This video is especially valuable if you:● Are losing weight but still feel metabolically unhealthy● Struggle with insulin resistance or slow metabolism● Want sustainable fat loss without damaging muscle● Care about longevity, strength, and aging well�� Recommended ResourceTo dive deeper into muscle-centric health, explore Dr. Gabrielle Lyon’sPlaybook:�� https://drgabriellelyon.com/playbook/� Pre-order bonuses include $400+ in value, plus access to a 6-week groupchallenge starting February 15.If this conversation helped shift how you think about muscle and health:�� Like the video�� Comment below What changed your perspective the most?�� Subscribe for more science-based discussions on metabolic health, fastingand longevity▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬⏱️ Chapters / Timestamps00:00 – Why Muscle Matters So Much (Intro & Core Idea)02:15 – Dr. Gabrielle Lyon: Muscle Is More Than Strength05:10 – Muscle as a Metabolic Organ Explained08:00 – How Low Muscle Mass Affects Fat Gain10:45 – Insulin Resistance, Muscle & Weight Loss13:30 – Hormones vs Calories: A Broken Model16:40 – Why Traditional Dieting Fails Long-Term19:30 – Muscle, Metabolism & Energy Production22:15 – Aging, Muscle Loss & Chronic Disease Risk25:10 – Intermittent Fasting and Muscle Preservation28:20 – Can You Lose Fat Without Losing Muscle?31:15 – Protein Intake, Muscle & Metabolic Health34:00 – Muscle-Centric Health vs Weight-Centric Health37:10 – Exercise, Resistance Training & Longevity40:00 – Common Myths About Muscle and Fat Loss43:15 – What Most People Get Wrong About Metabolism46:20 – Practical Steps to Build & Protect Muscle49:30 – Sustainable Fat Loss Without Starvation52:10 – Long-Term Health, Longevity & Muscle Mass55:00 – Final Thoughts: Rethinking Muscle & Health57:10 – Closing Message & Key Takeaways=============================�� BOOKS:�� The Obesity Code - Reviewing underlying physiology of weight loss anhow low carb diets and fasting can help.https://www.amazon.com/dp/1771641258?...�� The Diabetes Code - Reviewing how type 2 diabetes is a reversibldisease and dietary strategies. https://www.amazon.com/dp/B0795BLS8D?...�� The Cancer Code - Scientific exploration of how cancer developshttps://www.amazon.com/dp/0062894005?...�� Amazon:�� USA - https://www.amazon.com/shop/jasonfung�� Canada - https://www.amazon.ca/shop/jasonfung▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬�� Please visit our :-�� Website - https://www.doctorjasonfung.com�� Blog- / drjasonfung�� Community- https://www.thefastingmethod.com�� Facebook - / j Learn more about your ad choices.
