rmdaly, great advice. I was hesitant to post another reply b/c I wasn't sure how to word it but you pretty much said what I was thinking.
Connor, you're going to want to eat everything in site, that's what 14 year old boys do. The good thing is at your age, you can do that better than someone older. Your metabolism is probably in overdrive and your hormones are probably going through the roof, or will be soon. The best advice that I can give you is try not to worry about it too much right now. Don't try to rush it either. IMO working out 5 days a week for an hour or more can be excessive depending on your workouts. Talk to your parents about getting some healthier food for you try not to worry about the junk that the others are eating.
