I was super skinny too growing up. It wasn't until my mid-late 20's my metabolism started to slow down some. Even now in my early 50's I'm 6'2, but only 175. Growing up I would destroy my friends when eating. I could easily out eat any of them.

He's just like me when I was that age....he can out eat any of his friends easily. He can really pound the food down when he wants to, but it just doesn't matter, he doesn't gain any weight. He can run fast, jump high and has exceptional coordination, he's just super, super skinny.

I played high school basketball and no matter how much I ate and worked out I couldn't gain a single ounce. My coaches were baffled by it.
