Appetite -- the desire to eat food -- serves to balance energy intake with metabolic needs. It is regulated by a complex process that involves the digestive tract, hormones, and the brain. While the hypothalamus region of the brain is most closely linked with regulating appetite, certain brain chemicals are also being investigated for their effects. |
