There really isn't a way to lose weight quickly
, if you're going to it in a healthy manner.
In order to have a body that's healthy and that you can be proud of, you have to eat healthy and exercise.
For starters, give up sodas (including diet) and drink water instead. That alone could save quite a few calories, depending on how many sodas you drink each day. Additionally, eat a yogurt after exercising, instead of a candy bar, etc.
