The body stores carbohydrates for energy primarily in the form of glycogen. Glycogen is stored in the liver and muscles, serving as a readily available energy source during physical activity. When carbohydrate intake exceeds immediate energy needs, the excess is converted into glycogen through a process called glycogenesis. During periods of exertion or fasting, glycogen is broken down into glucose, supplying energy to cells. Maintaining adequate glycogen stores is crucial for athletic performance, endurance, and overall energy levels, making carbohydrate consumption essential for active individuals.
