Perform Ep 31: The Fundamentals of Nutrition, Hydration & Performance Fueling

In this episode, I answer your questions on nutrition, hydration, and recovery in our second audience Q&A. I start with what I call the 90%: the principles nearly every effective nutrition plan shares, from food quality and caloric balance to fiber targets, vegetable volume, color variety, and liquid calories. I then cover the four elements of fueling around training—glucose, amino acid availability, hydration, and GI distress—including the Galpin Equation for fluid intake during exercise. I walk through the three-step process I use to coach nutrition, which begins by adding nutrients rather than restricting them, and I explain when body recomposition is possible, what the protein data actually support, and why strength training is a bigger signal for muscle growth than protein. I close with what separates high performers from everyone else: energy management. This episode is for anyone who wants the fundamentals before the fine-tuning.
