Live Q&A episode (Ben Greenfield Life Podcast — Q&A 450, 2022-11-24) covering short, evidence-based news flashes and caller questions. Major takeaways: (1) a recent retrospective study associated frequent recreational cannabis use with lower total testosterone and worse sperm morphology—possible testicular (primary) effects and confounding lifestyle factors; (2) boiled potatoes score high on the satiety index while flaky baked goods (croissants) score low, and a randomized trial found gazpacho reduced later pizza intake versus bread; (3) ~20% of people may be ‘‘non-responders’’ to 150 min/week of low‑intensity activity—responses improve with doubled volume (~300 min/wk) or higher intensity plus resistance training; (4) supplements and devices discussed include C60 (Neural Rx) with anecdotal cognitive/neurological benefits, paraxanthine for alertness, methylene blue plus red‑light therapy (Revive Kineon), and practical notes on taurine and other supplements.
