Fueling the Next Generation: Understanding RED-S in Youth Athletes // 108

In this episode of The Hard Truth, Jeremy Fouts dives into one of the most overlooked yet critical topics in youth sports RED-S, or Relative Energy Deficiency in Sport.

Drawing from 27 years of experience in nutrition and performance, Jeremy breaks down what happens when young athletes consistently burn more calories than they consume and the serious effects it can have on growth, hormones, recovery, and long-term health. Speaking to both parents and athletes, he explains how under-fueling leads to fatigue, injury, irritability, and even stalled development. From spotting the warning signs to building smart fueling habits, Jeremy provides the blueprint to keep your athlete healthy, strong, and performing at their best.

He reveals the hard truth: Most young athletes aren’t underperforming from lack of effort they’re under-fueled. But the good news? RED-S is preventable with the right knowledge, nutrition, and daily consistency.

From sleep, hydration, and calorie tracking to meal planning and communication between parents and athletes, this episode is packed with actionable insight to help families build champions the right way fuel first, perform second, recover always.
