Andrew Huberman | Dr. Zachary Knight: The Science of Hunger & Medications to Combat Obesity
Understanding Hunger, Thirst, and Weight Regulation
This podcast episode features a detailed discussion between Andrew Huberman and Dr. Zachary Knight, a professor of physiology at UCSF. Dr. Knight's laboratory specializes in studying homeostasis, particularly focusing on the biological mechanisms that drive hunger, thirst, and thermoregulation. Key topics include the role of brain circuits in food consumption, how dopamine influences cravings and eating behavior, and the impact of new drugs like glp1 agonists (e.g., OIC) on weight loss and diabetes management. They explore how the brain integrates signals from the gut to regulate eating and drinking behaviors and the implications of these mechanisms for addressing obesity.
