My boyfriend did a diet called a Marine's diet as it was designed for Marine Commandos as their weights would fluctuate so much from being at home to being away. Its for 2 weeks, and you have to stick to it, down to the last letter and you should lose up to 2 stone in 2 weeks. It works by chemical reaction and he actually lost just over a stone and a half. Its very, very, very hard - for instance on the first day you have 3 boiled eggs for breakfast, 3 for lunch and 3 for dinner - nothing else, and you can only drink black coffee, water or pure lemon juice for the whole 2 weeks. If you think that you could do it, post back and I'll give you the details (I don't mean to underestimate you, but it really isn't easy, there's no way I could do it!) Good Luck anyway :)
