Filling up on nutrient-dense meals can help fill out your diet and allow you to realize the benefits of this program. Balance each meal with a good variety of healthful whole foods, such as fruits like apples, bananas, berries, oranges, peaches, pears, and so on. Vegetables offer essential nutrients that humans need to survive plus more energy than most people think. Fast food restaurants often use potatoes as a main ingredient because they are cheap and easy to find. Potatoes contain starch which gives them their bulk but also makes them high in calories. At first, yes, you should be able to eat one or two bananas per day as part of a fast. But once you start feeling better and have more energy, then stop eating them. Continue eating other healthy foods instead. Bananas are a great source of potassium and vitamins B6 and C. They're also a good source of fiber and manganese. Eating several small portions of healthy foods throughout the day instead of one large meal will keep you full between meals and prevent overeating.
