neuropeptide Y (NPY),
a natural substance that acts on the brain to stimulate eating. Laboratory animals injected with NPY greatly overeat. Substances that block the NPY receptor reduce the appetite. Leptin, a hormone that stimulates weight loss, reduces the output of NPY from the hypothalamus, a major production center. Another natural substance that stimulates the urge to eat is peptide YY. In animal experiments it has appeared to be at least as potent as NPY. Want to thank TFD for its existence?
