If you have to take a medication that has to be taken with food, then you can combine a mono diet with juice fasting. This means you can eat only one kind of fruit or vegetable. Grapes might be a good choice because they are low calorie, mostly juice and full of antioxidants. Eat only enough of the solid food to make it possible to take your medication easily and properly. As long as the fruit or veggie is eaten raw you will continue to cleanse, although at a slightly slower rate. This method will also work for people who are feeling ill from detoxing too fast, a simple piece of raw fruit can make all the difference in how one feels. While it may not be a pure fast, it is the next best thing, and you will still experience the cleansing and detoxification of your body. The key is to stick to only one kind of easily digested raw fruit.
