Jordan Sullivan: Fueling for Sports Performance & Body Composition

In this episode, my guest is Jordan Sullivan, APD, a registered sports dietitian and the founder of The Fight Dietitian (TFD), whose clients include UFC world champions, Olympians, and ultra-endurance athletes. We discuss performance nutrition, focusing on how to strategically use diet and nutrition to optimize an athlete’s physical performance, recovery, and overall health while aligning with their training intensity and volume. We take a holistic view of nutrition, considering individualized goals, lifestyle factors, training schedules, and meal frequency. We also cover core nutrition principles for non-elite athletes, including calorie estimates, macronutrient thresholds, and how to estimate calorie deficits for sustainable weight loss. Additionally, we explore different fuel sources used during exercise and how they shape an effective nutrition strategy for training and competition. Finally, we discuss pre-competition nutrition for endurance athletes, hydration, electrolytes, and extreme weight cutting. Read the full episode show notes at performpodcast.com.
