High-Fiber Carbohydrate Sources, You can eat almost unlimited quantities of foods that are high in fiber and should attempt to include them in all of your meals, except the Magic Window Meal. Vegetables such as celery, green peppers, cabbage, broccoli, and lettuce are so high in fiber and low in calories that you can eat as much of them as you want (for a comprehensive list of foods of various fiber contents, see Table 3.1). One leaf of lettuce only has 1 or 2 calories! The only thing you have to worry about from too much high-fiber vegetables is possible stomach distress.


Moderate-Fiber Foods

This category of carbohydrate source includes foods that do have significant amounts of fiber but cannot be eaten in unlimited quantities. Examples of moderate-fiber foods are whole-grain breads, bananas, peaches, corn, and carrots. While these foods are generally healthy and not especially fattening, they still contain a fair amount of calories and are not as filling as high-fiber foods. A slice of wheat bread, depending on the brand, can have 50 to 100 calories and a peach or carrot about 50. While this may not seem like much, it can add up after a while. Therefore, you should limit your consumption of them to one to two servings per meal, or five servings a day.
