Most of us assume America's biggest health problem is obesity. Dr. Gabrielle Lyon, a physician for 20 years and the founder of Muscle-Centric Medicine, argues we have spent 50 years fighting the wrong problem. We are not over fat, we are under-muscled, and obesity is a symptom of unhealthy skeletal muscle.

Michael pushes on where the argument is strongest and where it might miss. They get into whether you can have too much muscle, and why she believes GLP-1s could trade the obesity epidemic for a sarcopenia epidemic (too little muscle). They also cover the new dietary guidelines for protein, why your first meal of the day matters most, and the visceral "why" that keeps her Navy SEAL husband working 100-hour weeks. Her whole prescription fits in one sentence: lift hard, prioritize your protein, and get your mind right.
