    Physiologic rationale for why carbohydrate-depleted diet does not improve exercise performance

    Carbohydrate is a vital energy source during aerobic and anaerobic exercise. A 24-hour fast or low carbohydrate-normal calorie diet can nearly deplete resting glycogen reserves (McArdle, Katch, & Katch, 2015). Whereas a two to three-day carbohydrate-rich diet can increase glycogen store two times compared to a moderate carbohydrate diet (McArdle, Katch, & Katch, 2015). Any significant reduction in the body’s carbohydrate supply during exercise will result in fatigue and decreased performance. Glycogen serves as the body’s storage form of carbohydrate The liver contains about 100 grams of glycogen which is much more concentrated than skeletal muscle. In well-fed individuals’ intramuscular glycogen stores can reach 400 grams in absolute terms, greater…
