Satiety hormones, also known as hunger hormones, are hormones released by certain organs of the body that help control feelings of hunger and fullness. These hormones play an important role in how the body regulates energy balance and body weight.
Leptin
Leptin is a hormone produced by fat cells in the body. It helps to regulate energy balance and body weight by decreasing appetite and increasing metabolism. Leptin is important for long-term regulation of body weight; it is released when the body has stored enough energy, telling the brain that the body has enough energy and does not need to eat.
Ghrelin
Ghrelin is a hormone produced in the stomach that increases appetite and stimulates the release of growth hormone. It is released when the body is in a fasting state, telling the brain that the body needs energy. Ghrelin is important for short-term regulation of body weight; it is released when the body is in need of energy, telling the brain that the body needs to eat.
Cholecystokinin (CCK)
Cholecystokinin (CCK) is a hormone produced by the small intestine in response to the presence of food in the stomach. It helps to regulate feelings of fullness and satiety by decreasing appetite and stimulating pancreatic enzyme secretion. CCK is important for both short-term and long-term regulation of body weight; it is released when the body has enough energy, telling the brain that the body does not need to eat.
Peptide YY (PYY)
Peptide YY (PYY) is a hormone produced by the small intestine in response to the presence of food in the stomach. It helps to regulate feelings of fullness and satiety by decreasing appetite and increasing metabolism. PYY is important for both short-term and long-term regulation of body weight; it is released when the body has enough energy, telling the brain that the body does not need to eat.
Satiety hormones play an important role in how the body regulates energy balance and body weight. By regulating appetite and metabolism, these hormones help to ensure that the body has enough energy to function properly while also maintaining a healthy body weight.
