Essentials: How to Optimize Your Hormones for Health & Vitality | Dr. Kyle Gillett

About this video

Dr. Kyle Gillett explains how he evaluates and optimizes hormone health for men and women across the lifespan. He describes asking patients how their energy, focus, and athletic performance compare with when they were younger, noting that a pertinent symptom, not a pathology, is enough to justify hormone lab work, and that men are often hesitant to discuss libido or energy. Gillett presents his big six pillars of lifestyle intervention, with diet and exercise, especially resistance training, as the strongest, alongside stress, sleep, and other pillars, and argues small sustained efforts beat intense bursts followed by nothing. He explains PCOS as an underdiagnosed spectrum involving androgen excess, insulin resistance, and irregular or infrequent periods, and discusses tools such as metformin and inositol. He closes by arguing physical, mental, and spiritual health cannot be compartmentalized, and says caffeine affects hormones only if it affects sleep.
