This podcast episode (Ben Greenfield Fitness, Episode #175) contains news, listener Q&A, and a featured interview with Steve Bourne (Hammer Nutrition) focused on fueling for long workouts and multi-day endurance events. Key points: probiotics in fermented foods can remain viable without refrigeration if not pasteurized; alcohol sensitivity may relate to aldehyde dehydrogenase and histamine production; clenbuterol carries serious cardiac risks and is not advised; practical protein dosing (~20–30 g/meal; absorption ~8–10 g/hr); "hard gainers" may benefit from higher carb timing around workouts; cramping causes include fitness, flexibility and hydration—not only electrolytes; vegetarian pescatarian fat sources (eggs, full-fat dairy, sardines, avocados, nuts) are feasible; Steve Bourne emphasizes post-workout refueling within 30–90 minutes, finishing pre-race meals ~3 hours before start, and ~240–280 kcal/hr (avg athlete) during long events (Steve averaged ~300 kcal/hr at ~185 lb).
