What regulates hunger and satiety? What can an individual do to increase his/her own sensations of each?
Hunger and satiety are influenced by concentrations of glucose, amino acids, and lipids in the blood. Elevated blood glucose, amino acids, and lipids promote satiety. Decreased levels of glucose, amino acids, and lipids release neurotransmitters that stimulate hunger. The presence of food in the stomach and small intestine can trigger the release of GI hormones (CCK, PYY)—the majority of which promote satiety. Ghrelin is one of the few that doesn't promote satiety but appears to signal hunger to the brain.
