Excersise, and eat well. (you know what well means, if you eat something, make sure it's quality)
The carb craze is dumb. While the basis of the argument is decent, it will fuck you in the long run. Ask people who have been in shape for years if they watch thier carbs. Some might even tell you they "carb up" before a preformance day or something by eating pasta for lunch snack and dinner.
