Generally you don't want to loose that much weight in that short of time it is not good for you!

to be honest the best way is not to go on a diet as ive tried them all and diet pills and they dont work lol but just change your diet and go swimming 4-5 times a week for about an hour each time it tones your tummy and all your body up wonderful too ! i lost 2 1/2 stone since may its great and i eat loads too im just eating the right foods but instead of swimming try aqua arobics its great and really fun ! great question goodluck !
