This is a recorded interview (Longevity Show) between host Jason Hartman and guest Ben Greenfield (author of Beyond Training) about self-quantification, health, fitness and longevity. Ben emphasizes starting with internal biology via blood, saliva and gut tests rather than relying only on continuous wearable sensors (he is cautious about long-term RF exposure from always-on Bluetooth/Wi‑Fi devices). He recommends lab-based testing (direct-order labs like Wholesale Direct Labs or services like WellnessFX), periodic gut panels and hormone panels, and learning optimal (not population-average) reference ranges. On diet he focuses on nutrient density and digestibility (examples: properly prepared quinoa, sourdough bread, kale considerations). Exercise guidance centers on daily movement, heavy resistance a few times weekly, and short anaerobic sprints; obstacle races (Spartan/Tough Mudder) are promoted as accessible extreme events. He is skeptical of expensive supplement shortcuts (TA65) versus lifestyle interventions and mentions resources/apps (Safari Fit) and his site BenGreenfieldFitness.com.
