This episode I discuss how hormones from our gut, liver, pancreas and brain control our appetite– and the specific tools we can use to adjust those hormones in order to achieve specific goals. I explain the brain areas that control our desire to eat, and our desire to stop eating. I discuss a hormone we all can make that is regulated by UV-rays from sunlight that reduces our appetite. I also explain that when we eat controls our appetite and not the other way around (and how to leverage that fact). I describe how we are basically always eating until we reach a threshold level of fatty acids and amino acids in our gut and the factors that can alter that signaling and make us eat far more than we need. I also explain how insulin, glucose and glucagon work, why cholesterol is so key for ovary, adrenal, liver and testes function and how the ketogenic diet impacts glucose and thyroid levels. As always, I describe many tools: specific supplements, prescription compounds, specific types (and timing) of exercise to regulate hormones, specific timing and types of eating, ways to reduce sugar cravings by triggering the release of the hormone CCK, and more.
Note: A future episode will cover Thyroid hormone. Also, I misspoke when explaining POMC neurons. I said “P-M-O-C” but should have said “POMC”. Apologies. The name I gave for what POMC is, however, was correct: “proopiomelanocortin”.
