Neuropeptide Y is an appetite stimulator, while melanocortins suppress appetite. Many other chemical signals also play a role in the process. Leptin released from stored fat suppresses appetite and is important in long-term energy balance. Insulin decreases appetite. Gherlin from the stomach increases appetite and peaks before meals. PPY3-36 is produced by small intestines and released during meals to decrease appetite. Orexins are hypothalamic factors that increase appetite. Corticotropin-releasing hormone—another hypothalamic factor that decreases appetite. Stomach distension also decreases appetite.
