What is a good diet for a teenager or young adult?

Kso, Im looking for a good "Diet" or like a healthy meal plan. I do 15-20 minutes of running a day. Im trying to tone my body by july. So in like a month. I just recently started running and I need something thats easy, not something that you have to order food, or use pills or anything. Just like something that can help guide me in the direction of loosing the bit of weight I want to, and get rid of "love handles". Some exercise would also be a nice touch, Please help.. ?
