As a clinical nutritionist, Jay teaches glycogen management, which allows the dieter to sidestep the fat-storing cycle. Glycogen is carbohydrate that is stored in the muscle and liver. When a person cuts carbs, glycogen is depleted as the body begins burning fat as its primary source of fuel, while converting stored glycogen to glucose for secondary energy needs. The average person can store approximately 350-400 grams of carbohydrate as glycogen. The human body will convert excess carbs to glycogen first, instead of turning those carbs into fat. So the secret to permanent weight loss is to keep glycogen levels in check. Once a person lowers glycogen levels, then he or she can eat carbs safely until glycogen levels are full. Then the dieter must return to low-carb eating or run the risk of getting fat. This is why carb-cycling on The Fat Burning Diet allows a person to safely eat healthy high-carb foods every other day.
