10 -40 days on water only is the rec. timeline. if you notice yourself losing too much weight switch to juice. also check outthe rec. messages for how to break a fst that long in this forum and the Water Fasting forum. or get a book on it. you have to wean in solid foods again.

I'm doing just water and I'm on my 8th day and I've lost 24 pounds. But I am also overweight so that may be a factor.
