At your age I d combine a mix of dieting and exercise.Start with a light run each day and gradually build it up.As for dieting, I doubt you ll need to follow a strict dieting plan. Just eat sensibly, dont eat late at night and stay active.You ll be fine.http://healthy-weightloss-and-diets.com/
1- Do NOT decrease your caloric intake. Your body will pendulum react and never lose fat2- Increase your fiber naturally through foods3- You are growing so give yourself a huge break. The only reason to be concerned is for health and habits.4- Keep moving, but evenly not in stressful spurts5- Watch your liquid calories- they go straight to your blood stream and do bad things for levels and evenness
