Summary
The Huberman Lab Podcast, hosted by neurobiologist and ophthalmologist Andrew Huberman, explores the science and tools of everyday life. In this episode, Huberman discusses the role of hormones in metabolism, specifically focusing on thyroid hormone and growth hormone. He explains how these hormones impact metabolism and emphasizes the importance of maintaining healthy levels of iodine, selenium, and L-tyrosine in promoting thyroid hormone production. Huberman also discusses the relationship between hormones, insulin, glucose, and the ketogenic diet, and highlights the importance of carbohydrates in the healthy production of T3 and T4 to support the thyroid gland.
The episode further delves into the effects of exercise on growth hormone levels and insulin growth factor 1 (IGF-1). Huberman suggests that exercise, particularly weight training or endurance training for 60-75 minutes with a proper warmup and cool down, can lead to significant increases in growth hormone levels. He also discusses the potential benefits of supplements, such as arginine and ornithine, in increasing growth hormone levels, but cautions that they may have other effects on the body as well. Huberman advises caution when using saunas or other methods to increase growth hormone levels and encourages listeners to make informed decisions about hormone augmentation.
Overall, the episode emphasizes the importance of understanding the interplay between hormones and the brain, and encourages listeners to subscribe to the podcast and leave feedback.
