Episode 238 of the Ben Greenfield Fitness podcast (host Ben Greenfield with co-host Brock and guest Abel James) covers listener Q&A and short segments on running (stretching, sand vs. grass), carbohydrate/glycogen physiology, the ‘lean lifestyle’ project with Abel James, and many health/practical topics submitted by listeners. Major Q&A topics include electronic cigarettes and secondhand vapor, sleeping positions and ancestral sleep postures, recovery from pneumonia (natural supports and antibiotics mitigation), exercising in polluted cities (masks, timing, antioxidants), coconut oil vs. olive oil (smoke points, MCT oil vs. coconut oil, ‘bulletproof’ coffee), and supplements for pancreatic/beta-cell support (chromium, vanadium, bitter melon). The episode mixes research references, practical recommendations, product/brand mentions, and event announcements (Thailand triathlon, NYC clinic).
