Appetite is stimulated by all of the following, EXCEPT:

Appetite is influenced by many factors that are integrated by the brain, most impoantly within the hypothalamus. Signals that impinge on the hypothalamic center include neural afferents, hormones, and metabolites. Vagal inputs are paicularly impoant, bringing information from viscera, such as gut distention. Hormonal signals include leptin, insulin, coisol, and gut peptides. Appetite is increased by: NPY, neuropeptide Y Melanin-concentrating hormone (MCH) Agouti-related peptide (AgRP) Orexin Endocannabinoid Appetite is decreased by: MSH, melanocyte-stimulating hormone CA, cocaine- and amphetamine-related transcript GLP-1,glucagon-related peptide-1 CCK, cholecystokinin
