The hypothalamus is the brain structure that regulates appetite and signals when we are hungry. It has specific cells that produce hormones like ghrelin, which stimulates hunger, and leptin, which suppresses hunger. The hypothalamus also receives signals from the digestive system and blood glucose levels to determine when we need to eat.
