i did it for a few months not for me though, lost nothing. I did it in Ashbourne and transfer to Aston Village when i moved jobs. I think they have moved again, cant remember where i say the signs.
A girl i worked with lost loads. Funny thing was when i went to sign up got assessment. I think at the time every scales i stood on told me i was 11stone 7. In there scales i was 11 stone.
Personnally i think if you could get out for a walk for 30 mins 3-4 times a week you would do really well, plus it costs nothing.
