Video - Hunger and satiety

Hunger and satiety are regulated by a complex network of hormones and neurotransmitters that interact with the central nervous system. This network is responsible for signaling to the brain when you're hungry, what foods you should eat, and when you're full.

Some of the most important hormones involved in hunger and satiety include ghrelin, leptin, peptide YY (PYY), and cholecystokinin (CCK). Ghrelin is produced in the stomach and stimulates the release of stomach acids to digest food. Leptin is produced by fat cells and signals to the brain when you've had enough food. PYY is released by the small intestine after eating and inhibits hunger signals. CCK is also released after eating and reduces hunger by slowing gastric emptying.
