The Nervous System and Appetite. Your hypothalamus is the part of your brain that regulates appetite and hunger. In fact, your hypothalamus stays pretty busy with this function, taking in data from different sources.
In response, your hypothalamus gives you that full sensation. If you havenât eaten in a while and your stomach is empty, the opposite happens. You feel hunger. Other signals that tell the hypothalamus in your brain that you need to eat are chemicals released in response to eating or not eating. One of the major ones is a chemical called neuropeptide Y, or NPY. NPY is released by your brain when you havenât eaten in a while and your energy stores have dwindled.
