This episode of the Female Athlete Nutrition podcast is with REDs researcher, elite runner Melissa Lodge. Melissa opens up about how her personal experience with RED-S and underfueling led to a series of stress fractures and underperformance as an NCAA Division I athlete. Recovering from RED-S led to performance breakthroughs for Melissa, and also motivated her to study RED-S and advocacy for RED-S awareness and the dangers of underfueling through @FED_collaborative.  Melissa and I discuss the importance of studying female athletes, using research to inform practical takeaways for athletes, coaches, and other support staff. We debunk the hype around menstrual cycle nutrition, encouraging athletes to fuel enough always regardless of their menstrual cycle phase. We highlight how our bodies are trying to help us, and why fueling enough allows them to perform optimally: RED-S is a way our bodies protect us in a state of low energy availability. We finish by focusing on the importance of meeting our carbohydrate needs, why athletes are underfueling carbs, and avoiding low carbohydrate availability. And Melissa also answers our end of the podcast questions.
