Glycogen
Glycogen is stored carbohydrate found in muscles and liver that the body uses for energy.
Glycogen acts as a short-term energy reserve that the body can access quickly. It is stored with water, which affects body weight on the scale. When glycogen is depleted, weight often drops quickly due to water loss. When it is restored, weight rises again even if fat has not changed.
