What are ketones?

Ketones are like tiny energy helpers that your body makes when it needs fuel and can’t get it from food right away.

Imagine you're playing with your favorite toy car, but there’s no batteries, just a little bit of juice left in the tank. That's kind of like what happens when your body runs out of its usual fuel (like sugar), and starts making ketones to keep going. These ketones are like special backup batteries that come from breaking down fat.

When you eat a lot of food, your body uses sugar as its main energy source. But when you don’t eat for a while, maybe during a long game or at school, your body switches to using fat instead. This switch makes ketones, which go into your blood and power your brain and muscles.

Think of ketones like little snack bars that your body keeps in its pocket. When you're busy playing or thinking hard, these snack bars give you energy so you don’t get tired as fast. Sometimes people even use them on purpose to help their bodies feel stronger and sharper!
