Hi all, thought I would make an account after browsing so many times. I have been on the cambridge plan for 9 weeks now (i get weighed tomorrow) and in 8 weeks i had lost 1 stone 13 lbs. I am 100% on sole source so why is my weight loss slow compared to everyone else? My starting weight was 14.3 so I did have a lot to lose. My sister and her boyfriend are on it too and are ahead of me. What's wrong with me? My dress size hasnt changed either! I'm getting so frustrated. Is there anything I can so for maximum weight loss?
