Saw a similar thread to this on cambridge diet forum, so I've shamelessly plaguerised.
1- to be fitter and healthier and more up for things.
2- to not secretly cut the size out of my clothes.
3- to not be the funny one with good skin in my social circle but the foxy one
4- to buy any clothes I want, in any shop I want.
5- to do it in broad daylight and be relaxed
right over to you.............
