Sad to read about the young girl putting it back on again.Sounds as if she isnt getting any support at home or anywhere else.I seriously think that you need to increase exerise and control food intake to be succesfull.If you do one without the other the weight will come off but go back on very easilly.
Pity they didnt buy her a bike instead of sending her to the USA.
TBH I think its a case of losing weight because SOMEONE ELSE Wants you to as opposed, to WANTING to lose weight, I have done this myself in the past due to pressure and i'd lose a stone or 2, but because I was doing it for someone else, i'd get bored and put 2-4 stone back on again, it wasn't until I decided to do it, Because I WANTED TO, that I because successful , I do believe that to be the issue with her TBH Mate.
