How can I lose weight fast?

Ok, so I want to lose weight before summer, and that is 3 weeks away.
I want lose up to 20-25 pounds, but I want to do it safely, no diet pills, or anything.
Please give me some advice on how to lose that much weight before three weeks is up?

a good way to get rid of weight is if you don't feel like being outside doing somthing , but just feel like watching tv. when your show goes onto commercial do a few cruches or stretches or little excersices to help pass the time and burn some calories and if you are hungry instead of munching a potatoe chips or something full of fat and really greasy, munch on carrots or celory or something really healthy even a salad just not to much dressing. good luck...!!
