How to lose weight? 112 pounds and want to get down to 100 pounds.?

I am 5'2 and 112 pounds and have recently gained some weight. Usually I am in the 106-108 range but would ideally like to get down to 100 pounds because I feel like I am fat. Does any know of any good diet tips or any ways to lose weight fast?
