⩥ cholecystokinin. Answer: a hormone that is secreted by cells in the
duodenum and stimulates the release of bile into the intestine and the
secretion of enzymes by the pancreas; decreases appetite.
⩥ Gastric inhibitory polypeptide. Answer: Hormone, released by
intestine; Inhibits gastric secretion and motility and potentiates release of
insulin from beta cells in response to elevated blood glucose
concentration. stimulated by Presence of fat and glucose in the small
intestine; promotes satiety
⩥ Glucagon-like peptide 1 (GLP-1). Answer: substance released by the
intestines (ileum) in response to glucose, FA and fiber and travels to the
brain- terminates eating; inhibits gastric secretion and glucagon
secretion and enhances insulin secretion
⩥ Ghrelin. Answer: hormone secreted by empty stomach; sends "I'm
hungry" signals to the brain; increases with time since last feeding
⩥ Leptin. Answer: protein hormone secreted by fat cells; when
abundant, causes brain to increase metabolism and decrease hunger;
elevated in overweight/obese (leptin resistant)

loss by 12 weeks
