What Drives Hunger and Fullness: Inside Your Body’s Appetite Control System
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Every time you eat, or choose not to, your body is responding to an intricate communication network linking your gut, brain, and hormones. This episode explores how these biological systems determine when you feel hungry, how strongly you crave food, and when you feel full.
Learn how gut hormones such as ghrelin, GLP-1, and PYY interact with the vagus nerve and the hypothalamus to regulate appetite, and how sleep, stress, and circadian rhythm can disrupt these signals. You’ll also discover the difference between homeostatic hunger, which reflects true energy needs, and hedonic hunger, which drives eating for pleasure.
This episode is the first in a five-part series examining how appetite regulation works, why it sometimes goes off track, and how modern science is finding new ways to restore balance.
