I had the privilege of being a guest on this podcast and Jeff is a fantastic host. He asks thoughtful questions, creates space for real conversation, and knows how to balance the science with practical application. The triathlon community is lucky to have someone who tackles both the physical performance side AND the mental/emotional challenges athletes face. Whether you’re looking for evidence-based insights on nutrition and training or permission to prioritize yourself without guilt, this podcast delivers. Highly recommend!
Thank you for all of the research based information and insight. I don’t miss a week and love listening when doing my workouts. You are entertaining, informative and make me feel smarter about my training. Maybe we’ll see you at Ironman 70.3 Oregon in July. Keep up the awesome work.
Dr. Jeff presents a balanced and fair view of what training and supplementation modalities can help or harm triathletes. This is a fantastic resource for anyone just starting their triathlon journey to experienced veterans.
Jeff has done a tremendous job of putting together episode after episode of legit science based content to help endurance athletes be their best without being suckered into marketing hype on supplements / gimmicks. His guest interviews also are excellent and focused on triathlon.
What a lazy podcast. I don’t disagree with the premise of the episode, but it was mostly slander without any real science behind it. You dismissed peptide research by claiming there’s “no science,” yet animal studies are science—and you cited nothing showing lack of efficacy. Then you pivoted to say you were fine taking fruit that showed no benefit. The kicker, though, was when you claimed semaglutide can’t be taken orally because it would be broken down in the stomach. Ever heard of Rybelsus? That level of oversight isn’t skepticism—it’s just laziness.
