Huberman Lab

In this Huberman Lab Essentials episode, I explain how two key hormones control metabolism and discuss tools to enhance their levels to improve metabolic health. I discuss the pathways through which the brain and body interact to produce thyroid hormone and growth hormone, and how these hormones influence essential processes like tissue growth and repair, body composition, and energy production. I explain how thyroid hormone levels are influenced by key nutrients, such as iodine, selenium, and L-tyrosine. I also explain how practices such as exercise, sleep, meditation and sauna can offset age-related declines in growth hormone, to optimize overall hormone health and metabolism. Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday. Read the full episode show notes at hubermanlab.com.

My guest is Dr. Richard Schwartz, Ph.D., therapist, author, and founder of Internal Family Systems (IFS) therapy. We discuss how IFS views the mind as a collection of parts, each shaped by different life experiences—both good and bad, including trauma. To demonstrate how IFS works, Dr. Schwartz guides Dr. Huberman and you, the listener, through an example IFS session. We also explore how IFS and body awareness can help break harmful thought and behavior patterns, promote emotional healing, and build healthier relationships.

In this Huberman Lab Essentials episode, I explain how hormones regulate hunger, appetite and feelings of satiety (fullness), along with strategies to help control appetite. I describe how the body senses nutrient levels and how the brain processes these signals to stimulate hunger or suppress appetite. I also discuss how certain foods can help curb hunger, while processed foods and emulsifiers can interfere with satiety signals, leading to overeating. Additionally, I cover how lifestyle factors such as exercise and meal timing regulate blood glucose levels, which in turn impact hunger and appetite. Huberman Lab Essentials episodes are approximately 30 minutes long and focus on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, while our full-length episodes will continue to be released every Monday. This Huberman Lab Essentials is from the full-length Huberman Lab episode, “How Our Hormones Control Our Hunger, Eating & Satiety.” Read the full episode show notes at hubermanlab.com.

In this Huberman Lab Essentials episode, I explain how to optimize hormones—particularly testosterone, estrogen, and related sex steroids—to enhance fertility and overall well-being. I discuss the sources of testosterone and estrogen and how their levels fluctuate with age in both males and females. I also cover how behaviors such as exercise, cold and heat exposure, light exposure, illness, and breathing patterns affect hormones. Additionally, I examine specific supplements and replacement therapies, highlighting important precautions to consider when adjusting hormone levels. Huberman Lab Essentials episodes are approximately 30 minutes long and focus on key scientific insights and protocol takeaways from past Huberman Lab episodes. These short episodes will be released every Thursday, while our full-length episodes will continue to be released every Monday. Read the show notes for this episode at hubermanlab.com.
