My guest is Dr. Kyle Gillett, MD, a dual board-certified physician in family medicine and obesity medicine and an expert in optimizing hormone levels to improve overall health and well-being in both men and women. We discuss how to improve hormones using behavioral, nutritional and exercise-based tools and how to safely and rationally approach supplementation and hormone therapies. We also explore testosterone and estrogen and how those hormones relate to fertility, mood, aging, relationships, disease pathologies, thyroid hormone, growth hormone, prolactin, dopamine and peptides that impact physical and mental health and vitality across the lifespan. The episode is rich with scientific mechanisms and practical tools for people to consider.
