Muscle – The secret endocrine Organ to keep you healthy – A conversation with Dr. Gabrielle Lyon

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 Lyon
to explore why muscle is one of the most misunderstood—and most
important—organs in the human body. This discussion challenges the traditional
calorie-focused model of weight loss and reframes health through a muscle-
centric, hormone-driven lens.
Throughout this 58-minute discussion, you’ll gain clarity on:
● Why muscle plays a critical role in metabolic health and fat loss
● How low muscle mass contributes to insulin resistance and weight gain
● Why focusing only on calories often leads to failure
● The connection between muscle, fasting, and metabolic flexibility
● How muscle loss accelerates aging and chronic disease risk
● Practical ways to preserve and build muscle without extreme dieting
● Why hormones—not willpower—drive long-term weight regulation
Dr. Gabrielle Lyon explains how muscle functions as a metabolic organ,
influencing blood sugar control, energy production, and longevity. Dr. Jason Fung
adds crucial insight into how insulin, fasting, and metabolic health intersect with
muscle 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
