Hi there, I'm on week 3 of LL and so far so good . I met up with a friend who did LL before I knew her and she said it was great and that she lost 4 stone doing it. But she has put it all back on and said it really effected her metabolism. She started back on food after losing the weight and was having packs during the day and then a low fat dinner and was still putting weight back on. I know she didn't do the strict RTM as she said she couldn't afford it, but I do trust her when she says she stuck to 1000 cals a day for first month and still put on half a stone in that short time. She is really supportive of me doing it and wants me to do well but said she wouldn't do it again herself due to this. Is there any evidence that VLCD's can effect your metabolism? I know lots of people on here have and do maintain their weight so part of me tries not to worry about it. I just don't want to be that one person who does pile it back on really quickly. Right, rant over. Please tell me I'm being stupid to worry about it.
