Yeah, yeah, yeah - we all diet to lose weight (I know that). But why do we all want to lose weight? Is it to get healthy, to look good, to attract men, to fit in with your friends, because you think you ought to - or some other reason? It would be interesting to compare our reasons for wanting to be slimmer - and it would also be interesting to know what your targets are and why.
Personally mine is a health thing - my dad's side of my family has a history of dying early from heart problems and on my mum's side there is a tendancy to have early strokes and end up disabled for years and years. My goal is to walk in to my doctor's surgery and him say 'you are the right weight for your height'.
Of course looking nice would be a great side benefit as well - as would being able to walk in to any clothes shop and find clothes to fit me.
