How do people store nutrients?

After the process of saturation of the body with nutrients, part of it is deposited in a reserve as a reserve fuel in the form of glycogen or fat.
Glycogen is a carbohydrate. The body’s reserves are modest and are concentrated in the liver, as well as in muscle tissue. During exercise, glycogen breaks down, resulting in glucose. Glucose and fat circulate in the blood and thus provide energy to the muscles. If the level of glycogen stores in the human body reaches the norm, then excess carbohydrates will begin to turn into fat.
