When your body needs energy, it can draw on its glycogen stores. The molecules, made from glucose in the food you eat, are mainly stored in your liver and muscles. From these storage sites, your body can quickly mobilize glycogen when it needs fuel. What you eat, how often you eat, and your activity level all influence how your body stores and uses glycogen.

Low-carb and ketogenic diets, as well as strenuous exercise, all deplete glycogen stores, causing the body to burn fat for energy. Most of the carbohydrates we eat are converted to glucose, our main source of energy.

When the body doesn't need fuel, the glucose molecules are linked together in chains of eight to 12 glucose units which form a glycogen molecule. The main trigger for this process is insulin:. The amount of glycogen stored in these cells can vary depending on how active you are, how much energy you burn at rest , and the types of food you eat.

Glycogen stored in muscle is primarily used by the muscles themselves, while those stored in the liver are distributed throughout the body—mainly to the brain and spinal cord.

Glycogen should not be confused with the hormone glucagon, which is also important in carbohydrate metabolism and blood glucose control. At any given time, there are about 4 grams of glucose in your blood.

When the level begins to decline—either because you have not eaten or are burning glucose during exercise—insulin levels will also drop. When this happens, an enzyme called glycogen phosphorylase starts breaking glycogen down to supply the body with glucose. The Important Take-home Message Ensure you are optimizing glycogen stores before exercise, maintaining it during exercise, and replenishing it after exercise. References Goodman, MN.

Exercise physiologists normally consider glycogen's main function as energy substrate.

After exercise, the rate of glycogen synthesis is increased to replete glycogen stores, and blood glucose is the substrate.

Indeed insulin-stimulated glucose uptake and glycogen synthesis is elevated after exercise, which, from an evolutional point of view, will favor glycogen repletion and preparation for new "fight or flight" events.
