It is secreted from mucosal epithelial cells of the small intestine (duodenum), and stimulates the release of digestive enzymes and bile from the pancreas and gallbladder, respectively It is also produced by neurons in the enteric nervous system, and is distributed in the brain There are two main reasons regarding CCK’s ability to induce satiety: One is that meal-induced secretion of cholecystokinin activates the satiety centre of the hypothalamus in the brain so that the person feels full and stops eating (mediates satiety by acting on the CCK receptors distributed throughout the CNS) A second reason is that, because cholecystokinin inhibits emptying of the stomach, the sensation of satiety may be the result of distension of the stomach Study Normally, you secrete less CCK as you lose weight, so on a traditional diet you’ll lose weight but still crave unhealthy foods (less satiety after a meal) A study in the American Journal of Clinical Nutrition showed that people who were injected with CCK stopped eating their meals sooner than those without it This same study also looked at the effect of weight loss and ketosis on postprandial cholecystokinin concentrations The study showed that after 8 weeks of weight loss there were significant reductions in CCK, which was to be expected, but just one week of being in a ketogenic state returned CCK to baseline (pre-weight loss) levels (3) Note: As ketone levels rise, CCK is activated* Why is this? Ghrelin Ghrelin is a peptide hormone produced by ghrelinergic cells in the gastrointestinal tract, which functions as a neuropeptide in the central nervous system – It acts on hypothalamic brain cells both to increase hunger, and to increase gastric acid secretion Simply put, it’s referred to as “the hunger hormone” because it increases appetite It’s released from your stomach and intestines and whenever you eat a meal, ghrelin drops in response to nutrients circulating in your blood, when the stomach is empty, ghrelin is secreted Study A study published in the European Journal of Clinical Nutrition looked at hormonal alterations associated with weight loss induced by a...
