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.
When energy stores in fat get low, less leptin goes through the blood to the brain, causing the hypothalamus to increase hunger and slow metabolism. Insulin, which comes from the pancreas, tells the brain whether glucose (sugar) is available to be used as energy. Two other important hormones that help to regulate appetite come from the gut. Ghrelin [grel-in] comes mostly from the stomach and acts in the brain to increase hunger. GLP-1 is released from the intestine when food is present and acts in the brain to make us feel full.
