I am really upset about this. I did Cambridge oh, about ten years ago now, lost 5 stone. I've yo-yo'd but have never gone near the 14 and a half stone I once was. However, I struggle big time with maintenance (I am a binge eater.) Most years I've ended up doing a few weeks on Cambridge to keep the weight off. Last year I noticed that there was either something new in the Cambridge products or they took something out, I don't know, but they tasted horrible to me, I could barely force them down my neck. On the reccommendation of a friend I tried Exante. Stuck religiously to it for 2 weeks - lost 2lbs. I wasn't very good at being self-motivated so decided to try Lighter Life. I started on Feb 1 so I am now on day 10. I weighed in at 12'12 o) and I was weighed on Feb 4 for a motivator and had one - I had lost 5lbs. Great. Then on Feb 7th it was the group meeting, I'd lost a pound. I'm flagging tonight and weighed myself - I've GAINED a pound. How is that even possible on a week of less than 600 calories? I can't afford to stick on it indefinitely and nor do I want to. I really don't know what I should do. Have I ruined my metabolism?
