How to Make Better Sports Nutrition Decisions | Prof. Michael Gleeson

We Do Science with Dr Laurent Bannock returns, now with video! In this first episode back, Laurent welcomes Professor Michael Gleeson, Emeritus Professor of Exercise Biochemistry at Loughborough University, to explore the four Ps of performance nutrition: personalise, periodise, pre-fuel and prepare. Drawing on his research and experience in sports nutrition, Michael explains how this framework can help practitioners turn scientific evidence into practical decisions for their athletes. The conversation covers carbohydrate fuelling, hydration, gut training and supplements, alongside the importance of adapting nutrition strategies to training demands, individual preferences and the realities of competition. Laurent and Michael also discuss the role of wearables and testing in personalised nutrition, the challenges of supplement marketing, and why more information doesn’t always lead to better decisions. With examples from football and endurance sport, this episode offers sports nutritionists, coaches, students and athletes a practical look at choosing, applying and evaluating nutrition strategies.
