How can I loose cheek fat naturally ?

I am an fairly good Shape and have a nice built but I probably have a considerably high body fat though.added to that I have chubby check but I'm not chubby and I've read that your face slims out as you get in your early 20s and I'm only 17.I'm love the way I look and I consider myself attractive as girls do to but I feel like my chubby cheeks are childish so I thought maybe if I loose that body fat by running like I used to and sweating alot more and changing my diet than I can reach this goal.I will never get plastic sugary bur is there any suggestions!
