Ways for a 15 year old girl to lose about 3 pounds?

How should a 15 year old girl go about losing 3 pounds? I am already very active and running or getting some kind of intense workout 5 to 6 days a week. I am pretty small already but I think it'd be beneficial to my running if I shed just about 3 pounds. How should I go about this while still staying strong and not starving myself? Any help is greatly appreciated, thanks so much!
