Gabrielle Lyon

"Founder of Muscle-Centric Medicine® and author of the New York Times bestseller Forever Strong."

Dr. Gabrielle Lyon is a board-certified family medicine physician and the founder of the Institute for Muscle-Centric Medicine®. She trained in nutritional sciences and geriatrics at Washington University in St. Louis under protein researcher Dr. Donald Layman, and completed her residency at the University of New Mexico. Her clinical work reframes skeletal muscle as the organ most responsible for metabolic health, longevity, and healthy aging — not just strength or aesthetics. She runs a private practice in New York City, hosts `The Dr. Gabrielle Lyon Show` podcast, and has become one of the most cited voices in the muscle-centric and longevity movement. `Forever Strong` (2023) was an instant New York Times, USA Today, and Wall Street Journal bestseller.
