    Should you change your sports nutrition? - Ep. #217

    If you’re heading into a new season with the same fueling plan, it might be time to pause and ask one important question: "Should I change my sports nutrition?" In this episode, we talk through when it makes sense to change your sports nutrition and how to recognize signs that your current fueling approach may no longer match your training or your body. If you’re an endurance athlete or team sport athlete wondering whether your nutrition plan still fits your goals for this season, this conversation will help you think more clearly about when to adjust and when to stay the course. ------- Drop a question in our free Patreon Community and get access to bonus content with Bob and Dina by upgrading to the Gold Level membership.

    Dr. Marco Altini's Metabolic Efficiency Experiment - Ep. #215

    Your physiology doesn't always follow what the textbooks say. In this episode, we sit down with Dr. Marco Altini (ultra runner, endurance coach, data scientist, and thinker at the intersection of physiology, technology, and performance). Marco opens up about the moment he realized that doing the same high-carb diet he recommended to himself for years wasn’t actually working as well as he thought. He walks us through how shifting to a periodized approach - changing fueling based on training demands rather than sticking to a fixed carb ratio - improved his fat oxidation, gut health, and performance markers in ways he hadn’t seen before. Marco grounds the discussion in real data, including how his substrate oxidation changed after adjusting his diet and why better metabolic flexibility matters for endurance athletes. Along the way, we tackle common misconceptions about high-carb diets, the link between GI distress and fueling strategy, and why testing beats guessing when you want to understand your own response to food and training. What we cover in this episode: Why metabolic efficiency is not a single target, but a moving rangeHow nutrition periodization can support training without wrecking your gutThe overlooked connection between GI distress and everyday dietary patternsWhat Marco learned from tracking substrate oxidation instead of guessingHow fat oxidation and VO₂-related metrics can change with nutrition shiftsWhy weight loss is not the same thing as improved performanceThe role of testing in understanding what your body actually responds toHow to think critically about fueling without copying elite or influencer strategies Links: Follow Dr. Altini's Substack and find him on Instagram @altini_marcoMarco's Substack article "Periodized Nutrition and Metabolic Flexbility for Endurance Performance"Marco's Substack article "Learnings from a Year of Periodized Nutrition and Metabolic Testing"Bob's Metabolic Efficiency Training book (3rd edition) More about our guest:  Marco holds a PhD cum laude in applied machine learning, a M.Sc. cum laude in computer science engineering, and a M.Sc. cum laude in human movement sciences and high-performance coaching. He has published more than 50 papers and patents at the intersection between physiology, health, technology and human performance. He is the co-founder of HRV4Training, Endurance Coach at Destination Unknown, advisor at Oura, guest lecturer at VU Amsterdam, and editor of the Wearables department of IEEE Pervasive Computing. He loves running.
