Could some one be overweight but be physicaly fit?

I want to know if it is possible if I could be fit. I am an 14 year old that is 6 feet and weigh 185 pounds. I have been in tai kwon do since I was 5 and my kicks are so impressive at my dojo they have pictures of me in the lobby of me doing a kick that goes behind my head when I was 7. Iv also been a vegitarian for 11 months and lost 45 pounds sinse then. Among my friends I have the hardest and fastest kicks. My friends are physacaly fit and are nowhere near being overweight. I also have no problems with sports and am currentily playing volly ball with the best serve on the team. I personally think I am obese but all of my friends and family think I look average sized. I want to know if its possible I could be fit even though I am overweight.
