What should I do about the small amount of fat around pecs and abs?

I try working out every night and every time i work out I do an extra set for each muscle group I do. I can tell i have pecs but i have just a little fat around them that makes them less attractive and I also have some fat on my abs but when i flex I can tell I have some abs. Oh and I do not run and I watch my eating pretty well but Im 17 and whatever my mom cooks I eat lol please help i work hard for muscle and it dosnt show :-/
