CCK is a Satiety Hormone | Part 8 Neurobiology of Food Intake | Macronutrients Lecture 44

CCK is secreted in response to fat and protein intake to induce satiety at the level of the hindbrain and by stimulating PYY and inhibiting ghrelin.

It is secreted in response to fat and protein in the intestine. CCK stimulates the pancreas to release a cocktail of digestive enzymes required for digestion of carbohydrates, proteins, and fats. CCK also stimulates the gallbladder to release bile to enable emulsification of fats for efficient digestion. CCK stimulates chemoreceptors on the vagus which activates the nucleus tractus solitarius in the hindbrain to induce satiety. CCK also further stimulates PYY secretion from the distal intestine and inhibits secretion of the hunger hormone ghrelin from the stomach. CCK is an anorexigenic, satiety-inducing hormone.
