Chronic Fatigue Syndrome

The most common cause of fatigue that I see in my practice by far is diet. Diet can cause fatigue in a variety of ways. The most common is from eating too many high glycemic foods. High glycemic foods cause the blood sugar to spike because they either contain too much sugar or they are rapidly converted to sugar by the body. This includes grains and potato in addition to most sugars. On the glycemic index scale, which goes from 0 to 100 (with 100 equal to pure sugar), white bread is a 95 and baked potato is a 90. For all practical purposes these foods are the same as sugar to your body. Even whole grain breads, however, are about an 80, which is still high. Low glycemic foods include proteins (beans, nuts, soy, dairy, eggs, meat, fish, and poultry), vegetables, and even most fruits which contain a different type of sugar than most other foods.
