I am trying to lose 20 lbs. before Christmas (New Year's at the latest). I found weight loss plans online and one included a cleansing system of only drinking water and nothing else for 24 hours. Supposedly you can lose a pound solely from that, then just go on a strict diet from there. I was thinking of trying that, or is it not a good idea? I am not bulimic or anorexic but I think a cleanse will be good for my body.
