In this episode of Revolution Health Radio, Chris Kresser explores what biological age really means and examines the research behind today's most popular longevity claims. He explains how epigenetic clocks and DNA methylation are used to estimate biological aging, why these tests may be less precise for individuals than they appear, and what studies like the CALERIE trial tell us about slowing the aging process. You'll also learn why reversing a biological age number isn't the same as reversing aging, and how meaningful improvements in muscle strength, cognition, metabolic health, and physical function can be achieved at virtually any age. He also offers a practical framework to build a strong foundation of sleep, nutrition, movement, stress management, connection, and purpose before investing in advanced longevity technologies or supplements.
