Dr. Stacy Sims is an exercise physiologist and nutrition scientist specializing in sex differences in response to exercise heat stress, recovery, and nutritional adaptations for health, body composition, and maximizing performance. She authored one of Juliet's all time favorite health and fitness books, Roar, which is a comprehensive guide to nutrition and training designed especially for women. We talk about all our favorite topics as they relate to kids and really start to get an understanding of why kids aren't just little adults and how girls and boys are inherently different.
