What Causes ‘Hunger’ and How Is It Regulated?

Hunger is like a signal from your body. When you're hungry, it means your stomach needs food to keep going. It sends messages to your brain through special cells that tell you, 'I need more energy!' Then, when you eat and feel full, those same signals say, 'Stop, I'm satisfied now.' It's like a little conversation between your tummy and your brain.
