I tried to break a fast yesterday (it had been my third day of a water-only fast) with a small glass of grapefruit juice and a small handful of grapes but experienced bad diarrhea afterwards..Is this because my body is detoxing and won't let me break the fast until it's done?
That happens. Once you break a fast, you will sometimes experience diarrhea because you are restarting the digestive system again and the body is pushing out anything still left in the bowels/colon.
