This podcast interviews Dr. Stacy Sims, an exercise physiologist, about sex differences in training and nutrition for women. The conversation covers the menstrual cycle's impact on training and nutrition, highlighting the importance of individualized approaches rather than generalizing from male data. Dr. Sims emphasizes tracking menstrual cycles to identify patterns and adjust training intensity and nutrition accordingly, suggesting specific hormone tests (estradiol on day 2, progesterone on day 21) for deeper insights. She debunks myths surrounding low-carbohydrate diets and fasting for women, advocating for sufficient protein and carbohydrate intake, especially before and after workouts. The interview concludes with advice on adapting training and nutrition for perimenopause and postmenopause, emphasizing resistance training and high-intensity interval training to maintain strength and bone density.
