ELI5: Explain Like I'm 5

Calorie

Calories are like fuel for our bodies, just like gas or electricity is fuel for a car or a lightbulb. When we eat food, our bodies use the calories from that food to do things like walk, talk, and even breathe. The more calories we have, the more energy we have to do things.

Different types of food have different amounts of calories. Foods that are high in fat or sugar usually have more calories than foods that are high in protein or fiber.

It’s important to have the right amount of calories for our bodies. If we have too many, we might gain weight. And if we have too few, we might feel tired or weak. So, it’s important to eat a balanced diet with the right amount of calories for our bodies.
