In this episode, my guest is Dr. Stacy Sims, Ph.D., an exercise physiologist, nutrition scientist, and expert in female-specific nutrition and training for health, performance, and longevity. We discuss which exercise and nutrition protocols are ideal for women based on their age and particular goals. We discuss whether women should train fasted, when and what to eat pre- and post-training, and how the menstrual cycle impacts training and nutrition needs. We also explain how to use a combination of resistance, high-intensity, and sprint interval training to effectively improve body composition, hormones, and cardiometabolic health, offset cognitive decline, and promote longevity. We also discuss supplements and caffeine, the unique sleep needs of women based on age, whether women should use deliberate cold exposure, and how saunas can improve symptoms of hot flashes and benefit athletic performance. Dr. Sims challenges common misconceptions about women’s health and fitness and explains why certain types of cardio, caloric restriction, and low-protein diets can be harmful to women’s metabolic health. Listeners will learn a wealth of actionable information on how to improve their training and nutrition to enhance their health and how to age with greater ability, mobility, and vitality.
