Ohhhh, now I know the one your talking about... it's the "lemonade fast". Yes, I checked on that one also, but one of the things your supposed to do is drink a big jug of sea salt water, I'm not sure if it's everyday, and get ready to leave skid marks to the bathroom.
You can do this fast for as little as 10 days or as much as 30, most only do the 10 -14 day fast.I have heard the weight loss is just a bonus to the fast but that almost all of it comes back on when you start eating again.I still can't get up the nerve to do it, even if I did I won't be doing the salt water. Good luck if you decide to do it. I did tell my sister about it & she has'nt took the bait yet. Darn.
