I am so sorry. I will try to make this one a little longer!

That's what's 'wrong' with you. At your age with all the growth and stuff, you are bound to be a bottomless pit. Just keep it healthy and it won't come back to bite you when your metabolism slows later on.

Ok, still not a long post, but that's all I had to say.

@dennis, I agree for your height that weight doesn't seem too skinny at all. But if you feel that way, well then everyone here has give you some great advice. I agree with the poster who said that you will fill out as you get older. My brother could eat whatever he wanted for the whole of his teen years and stayed thin as a rail (well, he was about 6' tall) but now his shoulders have broadened and he's got some meat on his bones. Stick with the healthy eating and exercise.
