My co-worker and I did the slim fast diet one week when we were working up in northern MN. I lost 5 pounds, she gained 2.
Slim fast DOES work for me if I stick to the plan, which doesn't exactly happen for long. I don't have the willpower to only eat once a day. :)
I'm doing nutrisystem (sort of a modified plan, also using some weight watchers recipes) now and have lost 25 pounds. Only 25 to go. I say this as I sit here at 7:40am eating rice crackers! Of course, I've been up since 4 and at work for nearly an hour, so that counts as something, right?????? :)
