ELI5: Explain Like I'm 5

Caloric density

Caloric density means how many calories are in a certain amount of food. Think of it like a toy box. A big toy box might have lots of toys, just like a big plate of food might have lots of calories. But a small toy box might not have as many toys, just like a small plate of food might not have as many calories.

Some foods have lots of calories in a small amount of space, like cookies or cake. Other foods have less calories in the same amount of space, like vegetables or fruits.

When we eat more calories than our bodies need, we can gain weight. So, it's important to pay attention to the caloric density of the foods we eat and make sure to eat a balanced diet!
