Hi I have done slimming world a few years ago and lost all my weight, but like most people, after a while some of it went back on, so last year I did weight watchers, I am glad to say I lost most of it , but I couldn't loose the last few pounds. I decided to count my calories and hit the gym, which has worked. But now I'm finding it hard to keep at my target weight. I seem to yoyo.
