Your body sends out messages when it needs food, like a tiny robot inside you saying, 'Hey, I need more energy!' This happens because your brain gets a signal from your stomach and blood sugar levels. When those signals go up, you feel hungry and want to eat.
Examples
- You feel hungry when you've been waiting a long time between meals because your stomach is telling your brain it needs food.
- Your body signals hunger if you skip breakfast and then try to focus on school work.
- If you eat a big meal, your brain might not signal hunger for several hours.
