Cholecystokinin (CCK) is released by the small intestine in response to food and helps signal feelings of fullness by slowing down stomach emptying and stimulating the release of digestive enzymes. Insulin is released by the pancreas in response to rising blood sugar levels and helps to lower them. Neuropeptide Y (NPY) stimulates appetite and food intake. Ghrelin is produced in the stomach and stimulates hunger.
