How is energy stored in the food you eat?

For example, if you eat a large meal and your body doesn’t need that much glucose right away, insulin will help your body store it to convert to energy later. Insulin does this by turning the extra food into larger packages of glucose called glycogen. Glycogen is stored in the liver and muscles.

Is energy stored in food?

The food we eat contains stored chemical energy. As the bonds between the atoms in food loosen or break, a chemical reaction takes place, and new compounds are created. The energy produced from this reaction keeps us warm, helps us move, and allows us to grow. Different foods store different amounts of energy.
