I asked this question a few months ago in the Master Cleanse Forum and a woman answered me and said that all of her celulite dissappeared after 20 or 21 days on the MC. I've only done the Master-Cleanse for 7 and 10 days, but during those cleanses I noticed a reduction in cellulite. I'm sure that you'll lose some, and not gain any. Anyway... I hope more people answer your post this time, I'm really curious too.
