How to Control Your Metabolism by Thyroid & Growth Hormone

About this video

Huberman explains metabolism through thyroid hormone and growth hormone, emphasizing that the brain and hormones engage in a bidirectional conversation. On thyroid, Huberman explains that for most people who consume no carbohydrate for a long period, T3 and T4 levels will go down in his account, which matters when reintroducing foods that require thyroid metabolism, while he names selenium, tyrosine, and iodine as the three inputs he discussed for healthy thyroid levels absent an underlying condition. Huberman acknowledges disagreement from long-term ketogenic dieters. Turning to growth hormone, Huberman explains that growth hormone-releasing hormone from the brain tells the pituitary to release growth hormone into the bloodstream, where it acts on muscle, ligaments, bone, and fat to increase metabolism, repair, and growth, working in parallel with thyroid hormone. He describes the extremes: Huberman explains that too little growth hormone from birth produces very short stature, while too much produces very large growth and acromegaly, with most people falling in a middle range.

Key takeaways

• Huberman explains thyroid and growth hormone as parallel systems that increase metabolism and tissue repair.
• Huberman names selenium, tyrosine, and iodine as key inputs for thyroid hormone production.
• Huberman argues that long-term carbohydrate absence lowers T3 and T4 for most people.
• Huberman describes growth hormone extremes as short stature at one end and acromegaly at the other.
• Huberman frames brain-hormone control as a bidirectional conversation.
