Your butt is not about aesthetics. It is a longevity organ that directly impacts metabolism, brain optimization, resilience, and how long you stay strong as you age. In this episode, you’ll learn why strength training and protein intake matter more than body fat percentage, how mitochondria drive human performance and recovery, and why building muscle protects your brain, stabilizes mood, and supports long-term longevity. This conversation reframes biohacking, anti-aging, and health from weight loss to muscle span, the length of time you live with strong, functional skeletal muscle.

Host Dave Asprey sits down with Gabrielle Lyon, an accomplished physician and New York Times bestselling author of Forever Strong: A New, Science-Based Strategy for Aging Well, and author of the upcoming The Forever Strong Playbook, releasing January 27, 2026. Dr. Lyon pioneered the Muscle-Centric Medicine® approach, which places muscle at the center of disease prevention, metabolic health, and true vitality. She has trained elite athletes, military operatives, and public figures, while also living this philosophy at home as a mother of two with her husband, a retired Navy SEAL. 

Together, they break down why intermuscular fat may matter more than body fat percentage, how skeletal muscle drives insulin sensitivity and lowers inflammation, and why becoming physically stronger improves brain function and neuroplasticity. They explore protein needs across the lifespan, fasting, ketosis, carnivore-style nutrition, supplements, sleep optimization, and the real tradeoffs of GLP-1 drugs, including the risk of accelerated muscle loss if strength and protein are neglected. The conversation also covers mindset, hormesis, and why physical resilience creates emotional regulation and clearer decision-making in a world increasingly shaped by AI and convenience. 

This episode is essential listening for anyone serious about biohacking, hacking human performance, longevity, mitochondria, neuroplasticity, nootropics, metabolism, functional medicine, anti-aging strategies, supplements, and living Smarter Not Harder, ideally with a cup of Danger Coffee in hand. 

You’ll Learn: 

• Why your glutes and skeletal muscle are critical drivers of longevity and brain health 

• Why intermuscular fat can matter more than body fat percentage for metabolic dysfunction 

• How strength training improves neuroplasticity, cognition, and emotional resilience 

• Why protein needs increase with age and why outdated limits can hold you back 

• What GLP-1 drugs get right, where they fail, and how to protect muscle span 

• Why progressive stimulus beats lifting heavy for long-term strength and injury prevention 

• How sleep optimization and recovery support mitochondria and human performance 

• How building muscle creates clarity, resilience, and better decision-making
