Summary

Is Ozempic the miracle weight loss drug everyone claims, or are we creating a generation of "sarcopenic, chalky skeletons"? In this Fitness Fridya episode, Dr. Stacy Sims and I dive into the truth. We discuss the peptide craze, exploring why BPC-157 might be the only one worth considering, and why WADA banning it actually proves it works. Plus, Dr. Sims settles the sauna debate once and for all - explaining why infrared saunas are basically expensive cold rooms and why Finnish saunas deliver real results for women's hormones and metabolism. Dr. Stacy Sims is an international exercise physiologist and nutrition scientist who specializes in sex differences in training, nutrition, and environmental conditions. She's the author of "Roar" and "Next Level" and has spent decades researching how women's unique physiology requires different approaches to health and fitness.
