I started as size 14 and now a size 10 and have lost 3lb's short of 2 stone. It was really weird, cos i sort of missed out size 12 clothes. It must have been after loosing about a stone, that all my clothes felt really baggy, it was then that almost everyday i would have different people saying 'Have you lost weight?' THAT REALLY HELPS THE MOTIVATION. I dwindled abit after loosing a stone, because it was slow and people weren't commenting anymore. Just got to keep motivated and you're bound to need new clothes soon x
By the way, my friend who started as size 18, has also lost 2stone, but is still in size 16 clothes, not sure how it all works.
