maybe you could set up a reward system. my friend and i used to always eat heaps of junky crap from the canteen at school, like donuts, ice cream, you know the stuff. and it adds up to about $3/week out of our pocket money. we decided that if we dont buy a single thing from the tuckshop, the money we'd save would go towards us going to a theme park in the holidays that are coming up. it works really well, and it helps if you have a friend for encouragment. so maybe you could set up a reward system at home, like fruit for dessert, and well, whatever you want, you can make it as strict as you like, then say, you get a new piece of clothing or shoes or jewellery, or whatever takes your fancy, if you stick to that diet for however long you want to make it. it all depends on what your diet is like now. you cant expect to go from unhealthy to healthy in one day, thats why you choose the amounts of food and the time limit. good luck, keep me posted
