We assume that the person described here starts the work period eagerly, using stored glycogen at the beginning of the work session. Muscle glycogen remains is the major source of energy during the first half-hour. After this period we see that fatty acids and blood glucose takes over as important energy sources.
If people consume more carbohydrates than they need at the time, the body stores some of these carbohydrates within cells (as glycogen) and converts the rest to fat. Glycogen is a complex carbohydrate that the body can easily and rapidly convert to energy. Glycogen is stored in the liver and the muscles. Muscles use glycogen for energy during periods of intense exercise. The amount of carbohydrates stored as glycogen can provide almost a dayâs worth of calories.
