How does the nervous system regulate appetite?

The arcuate nucleus of the hypothalamus controls appetite and contains neurons which express pro-opiomelanocortin (POMC) and cocaine- and amphetamine-regulated transcript (CART), which decrease appetite and increase energy expenditure, and neurons which express agouti-related protein (AgRP) and neuropeptide Y (NPY), …

What causes hunger sensation?

Hunger hormone

The brain triggers the release of a hormone called ghrelin in response to an empty stomach or in anticipation of the next meal. Ghrelin signals the body to release stomach acids to digest food. If food is not consumed, the stomach acids begin to attack the lining of the stomach, causing hunger pains.
