Body Composition & Fueling: Performance, Risk, and Why Under-fueling Harms Athletes

Описание: In this episode of the Fast Talk Podcast by Fast Talk Labs, we dive into a critical and often misunderstood topic for endurance athletes: how body composition and fueling strategies influence performance — and the significant dangers associated with under-fueling. Drawing from a TriDoc Podcast swap episode, host Jeff Sankoff is joined by dietitian Alex Larson and coach Juliet Hochman to unpack how athletes can pursue body composition goals safely while avoiding under-fueling, low energy availability, and performance setbacks. 

🧠 In this episode, you’ll learn:
• Why fuel intake matters as much — if not more — than body composition for performance
• How chasing low body fat can lead to low energy availability and health issues like RED-S
• Why under-fueling compromises immune function, recovery, and performance
• How different body types and genetic factors influence optimal fueling and lean mass goals
• Practical strategies to adjust body composition sustainably, without jeopardizing training
• Tips for how coaches and athletes can navigate body image, performance pressure, and nutrition discussions

🎯 Whether you’re an athlete chasing performance gains or a coach guiding others, this episode helps you:
• Reframe body composition goals in a healthy, evidence-based way
• Reduce performance risk by prioritizing adequate fueling
• Understand the tradeoffs between lean mass, body fat, and energy availability
