I'm at work, so I'll have to make this quick (I can write a lot on the virtures of excercise and stuff). If you think you need to lose weight, something obviously isn't working for you, and you have to change your lifestyle. Eating healthy is one way (notice I said healthy and not dieting - huge difference). The most important thing is to get some excercise. Even a walk after dinner helps. Just eating healthy is a start, but that is only one step.
