Visceral fat, subcutaneous fat, Prenuvo MRI scans, and the truth about belly fat

Host Dave Asprey sits down with Dr. Sean O'Mara, a former undercover narcotics agent, criminal prosecutor, emergency medicine physician, and retired U.S. Army Colonel who assisted the White House and Senior Executive Service, treating Vice President Dick Cheney, former President Bill Clinton, and Secretary of State Colin Powell. Today he's recognized as the world's most experienced physician in eliminating visceral fat and epicardial adipose tissue (EAT), the inflammatory fat now linked to nearly every major chronic disease and accelerated aging. He founded Influence Medicine, a specialty built around helping senators, heads of state, and top executives optimize their biology so they can perform and lead at the highest level.  

Dave and Dr. O'Mara break down the real difference between visceral fat and subcutaneous fat, why a visible six-pack might signal hidden disease, and how MRI scans reveal what your mirror never will. They dig into the biohacking strategies that actually shift your body composition: fasting protocols that build beneficial fat instead of burning it away, microbiome optimization for fat metabolism, and the supplements and functional medicine tools Dr. O'Mara uses with his highest-performing clients. They also cover the gut-hormone connection driving modern metabolic dysfunction, why political leaders are quietly getting scanned, and what your face reveals about your visceral fat levels before you ever step on a scale.
