How to Control Your Metabolism by Thyroid & Growth Hormone

This episode I discuss metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn’t just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanism and tools grounded in specific mechanisms are discussed. Thank you for your interest in science!
