What does hunger do?

Hunger triggers a physiological response in the body, signaling the need for food intake to maintain energy levels and support vital functions. It can lead to physical sensations like stomach growling and fatigue, as well as psychological effects such as irritability or difficulty concentrating. Prolonged hunger can result in malnutrition and health complications, affecting both physical and mental well-being. Additionally, hunger can influence behavior, leading individuals to seek food aggressively or make less healthy food choices.
