Energy balance holds when the calories you eat match the calories you burn. This video covers how leptin, insulin, ghrelin, PYY, and GLP-1 signal to neurons in the hypothalamus to control appetite and metabolism, and how this connects to obesity, type 2 diabetes, and GLP-1 drugs such as semaglutide.
Key concepts covered: energy balance, thrifty gene hypothesis, leptin and adipose signaling, POMC and NPY/AGRP neurons, anorexigenic vs. orexigenic pathways, insulin, ghrelin, PYY3-36, GLP-1 receptor and semaglutide, obesity and type 2 diabetes.
