Hi Brandy726, To answer your question "How does a Water Fast work." You just drink water, "nothing" else.
I have fasted by way of the Master Cleanse, (the longest one was 21 days) Juice Fasting, and water fasting. Of course the Master-Cleanse and juicing are not fasts, they are a restricted way of eating. I prefer water fasting. 10 days of Water Fasting is equivalent to 30 days of juice fasting. I want to tell you I do not have a weight problem; I have a health problem. This is why I fast.
It has been my experience that nothing compares to the Water Fast as a means of eliminating waste from the blood and the tissues. Unfortunately for me, fat is lost faster than any other tissue of the body while fasting.
I think that Water Fasting is a healthy way to lose weight
