What Does Our Body Do with the Glucose from a Meal?

Insulin directs muscle, fat tissue, and the liver to use glucose, fructose and galactose as the primary fuel. This allows for a lot of carbohydrate entering the body from a meal to be used for energy immediately. In

addition, insulin directs muscle and liver, and to a lesser extent other tissue, to store extra carbohydrate as glycogen. Glycogen is composed of large branching links of glucose and is very similar to plant starch. However, only so much glycogen can be made and stored, since it is meant to be a short-term not a long-term energy reserve.
