How to Control Your Metabolism by Thyroid & Growth Hormone
1:46:00
Published: Mon Apr 26 2021
Description
This episode discusses metabolism and how our thyroid hormone and growth hormone control our metabolism. I also clarify that metabolism isn't just about burning energy, it’s about converting energy from different sources into fuels for building and repairing our tissues such as muscle, brain, and tendons and mobilizing energy from body fat storage. I discuss the role of iodine, selenium, and salt for thyroid health, and how specific exercise protocols, amino acids and temperature can dramatically shift levels of growth hormone release in waking and in sleep. I also describe the current landscape of prescription compounds, peptides and other factors for changing levels of thyroid and growth hormone, and some of their risks. Throughout the episode, mechanisms and tools grounded in specific mechanisms are discussed.

Thyroid hormone and growth hormone are essential for metabolism, tissue repair, maintaining cognitive function and preventing dementia.
13:14 - 24:37 (11:22)
Summary
Thyroid hormone and growth hormone are essential for metabolism, tissue repair, maintaining cognitive function and preventing dementia. Adequate iodine levels are necessary for the production of thyroid hormone.

Many foods are sources of selenium, an important mineral for thyroid health and increasing thyroid hormone, such as pork, beef, turkey, chicken, cottage cheese, eggs, and brown rice.
24:38 - 32:37 (07:59)
Summary
Many foods are sources of selenium, an important mineral for thyroid health and increasing thyroid hormone, such as pork, beef, turkey, chicken, cottage cheese, eggs, and brown rice. However, Brazil nuts are the richest food source of selenium, with six to eight nuts providing 550 micrograms of selenium, while all other foods contain only 30 to 50 micrograms.

Iodine, selenium, and L-tyrosine are crucial for thyroid health since they enable thyroid pathways, support bone, muscle, and cartilage repair while allowing the thyroid hormone to take glucose to tissues for better brain function, cognitive health, and high metabolism.
32:37 - 42:14 (09:37)
Summary
Iodine, selenium, and L-tyrosine are crucial for thyroid health since they enable thyroid pathways, support bone, muscle, and cartilage repair while allowing the thyroid hormone to take glucose to tissues for better brain function, cognitive health, and high metabolism.

Maintaining healthy levels of thyroid hormone is crucial for brain function as 75% of metabolism is from the brain.
42:14 - 50:51 (08:36)
Summary
Maintaining healthy levels of thyroid hormone is crucial for brain function as 75% of metabolism is from the brain. The administration of drugs or the removal of the thyroid gland can help regulate thyroid hormone levels if necessary.

Delta wave activity & slow wave activity in the brain are important for growth hormone release, which helps with metabolic functions, fat loss, and tissue repair.
57:57 - 1:06:49 (08:52)
Summary
Delta wave activity & slow wave activity in the brain are important for growth hormone release, which helps with metabolic functions, fat loss, and tissue repair. Meditation practice and melatonin supplements can increase this growth hormone release by helping to achieve deep sleep with delta wave activity.

Weight-bearing exercises that lead to getting close to the final repetitions but not pushing through, can lead to 300-500% increases in growth hormone, but exercise duration and body temperature are important factors.
1:06:49 - 1:14:28 (07:38)
Summary
Weight-bearing exercises that lead to getting close to the final repetitions but not pushing through, can lead to 300-500% increases in growth hormone, but exercise duration and body temperature are important factors. Additionally, the effects on IGF-1 and growth hormone differ between men and women.

Arginine and ornithine can increase growth hormone levels substantially, but using them with the specific goal of releasing growth hormone can short circuit the effects of exercise on growth hormones due to temperature.
1:14:28 - 1:30:11 (15:42)
Summary
Arginine and ornithine can increase growth hormone levels substantially, but using them with the specific goal of releasing growth hormone can short circuit the effects of exercise on growth hormones due to temperature.

Summary
Entering environments where it's very hot for short periods of time, anywhere from 20 minutes to 30 minutes, has been shown to increase growth hormone release 16 fold and provide a significant decrease in cortisol, a stress hormone. However, it did not change testosterone, DHEA or prolactin levels.
