How can I easily and healthily lose a little weight as a teenager?

I’m not extremely overweight or anything. In fact, I’m five four and 120 pounds, and mostly muscle at that. But even when I run and work out, the fat between my legs and on my stomach won’t go away, although I can feel and see that I’m building muscle. As a teenage, I’m pretty self concious about this and my track season is comming up so I have to be in the best shape possible. And I am NOT the starve myself type. I like food way to much :). So any suggestions on how to lose the last five or seven pounds?
