Carbohydrates are chains of small, simple sugars that are a major source of energy. When consumed in the body, they are broken down in the stomach by various enzymes and absorbed as sugar or glucose into the blood circulation. When carbs are eaten in excess, some of them are stored for future use in the liver as glycogen, the rest are turned into fat. This process explains why everyone wakes up in the morning, often after 15 hours of no eating and the blood sugar is not zero. It’s also the difficulty you might have if you attempt to exercise vigorously on the HCG diet—you simply have little sugar stored in the liver which is needed immediately for exercise. Carbohydrates come in two forms: simple sugars like glucose, fructose, lactose and sucrose which are small molecules and are quickly absorbed by the stomach and raise blood sugar. Other carbs are larger molecules and take longer to process. The latter group includes starch, and cellulose. They are found in vegetables and unrefined whole grains. Carbohydrates are rapidly absorbed from the stomach, and elevate the blood sugar. If not used for fuel by immediate exercise, insulin pours out of the pancreas to lower the blood sugar by turning it into fat. In the HCG diet, eliminating almost all carbohydrates is the key to increasing metabolism and preventing hunger.
