How does your body use carbohydrates and fats

One of the primary functions of carbohydrates is to provide your body with energy. And the fats store the energy

When you eat carbs, your body breaks them down into simple sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as an energy source.
