The glucose absorbed right after a meal is called postprandial glucose. After the carbohydrates from the meal are broken down to simple sugars and eventually utilized or stored in the body, most of the glucose not burned is stored as glycogen in the liver and muscle tissues. Glucose is continually utilized to fuel our cells and especially our brain. Our brain use makes up 80 percent of our caloric needs in the resting state. After the meal’s contribution is utilized and digestion ceases, we start to gradually burn down our candle of stored glycogen in the liver as our glucose source. This catabolic or breakdown phase, when stored glycogen is our main source of glucose, is called glycolysis. When glycogen stores are being burned for glucose, toxins are better mobilized for removal and repair activities are heightened. Spending time in glycolysis, while resting the digestive apparatus in this non-feeding stage, is important for health and a long life
