This episode of the Female Athlete Nutrition podcast is with  World-renowned sports dietitian and nutrition researcher Professor Louise Burke. For over 40 years, Professor Burke has been studying elite athletes, and today we take a deep dive into her research into the ketogenic diet and performance.  We discuss why low carb, high fat diets impair elite performance, as well as immune and bone health, and iron status. We also chat about ketone supplementation and the use of different diets for different athletes. Professor Burke talks about her study looking at athletes training on a low carbohydrate diet, but fueling with carbs on race day, highlighting the need to practice fueling in training, in order to optimize performance. A leading voice on RED-S, we discuss the difference between RED-S and low energy availability, as well as the potential for overdiagnosis. We finish off with our usual end of the podcast questions.
