What happens when elite fitness doesn't equal health? In this episode of Extend, Ben Greenfield joins me to discuss how blood tests showed he was metabolically compromised despite being an Ironman competitor, and shares the comprehensive testing protocols that changed his approach to wellness. We discuss the critical difference between fitness and health, Ben's biomarker testing strategy using wearables and lab work, and why he embraces hormesis - the concept that controlled stressors like heat, cold, and plant compounds build resilience. We also dive into why dietary diversity beats restrictive elimination diets and the importance of cycling supplements rather than continuous use. Ben Greenfield is a biohacker, bestselling author of "Boundless," podcast host, and founder of Kion supplements. A former professional athlete turned health optimization expert, he now coaches high-achievers on personalized health protocols.
