Question: why do people feel hungry

Gliday Yuka answered on 16 Jul 2025:

People feel hungry because their body needs energy and nutrients to function, like a phone needing a recharge. When your stomach is empty or blood sugar drops, the hormone ghrelin signals your brain’s hypothalamus to trigger hunger, telling you to eat.

Meanwhile, hormones like leptin signal when you’re full. Hunger can also be sparked by habits, like eating at regular times, or environmental cues, like smelling fresh pizza. For example, if one skips breakfast, their stomach might growl by lunch because their body’s saying, “I need fuel to keep going!” It’s your body’s way of ensuring it gets the energy and nutrients to stay healthy and active.
