Craig, for guys, being fit is a very deal, and girls love it! im not going to lie. the first thing i would advise you to do, is get yourself involved in school. play sports, do clubs ANYTHING that will get you away from places that you eat. i see alot of guys in my school that stay after and work out in the weight room together for hours at a time, i think its great.. the thing about that is you can't workout then go home and eat or else ull find yourself gaining more weight. also, dont let yourself get down if u find u gain 5 pounds or more building muscle because muscle weighs more than fat. and DO NOT, i repeat DO NOT go crazy eattin if you give up one day, because i know i do that alot. i hope this helps
