First off, I'm assuming those of you who said "I'm skinny and I want to get fat" don't really mean that. Being fat is unhealthier than begin skinny (unless severe case) - higher risk of heart attack, higher cholesterol, etc. I'm assuming you just don't want to be seen as skinny anymore - whether that means getting muscle or fat. As some people said already, you want to get "buff" 😀
I'm in the same "predicament" Throughout high school, I was always around the 120-130# range at 5'7" - 5'10" Pretty skinny yes...I ate what I wanted, whenever I wanted, and etc. Never gained anything. Of course, I played sports daily, but I also sat on my @$$ at the computer playing games and stuff. 🙂
Now I'm 21 and about done with college. I'm still 5'10", but I'm about 155#s. The "Freshmen 15" holds true. I gained 15 pounds easy freshmen year. I'm not skinny anymore, but slim 😀. I've been lifting also, so I'm guessing that helped a bit also.
Summary: Weight increases with time 😀
For those of you who want to LOSE weight, I have one question: do you do anything outside the computer? I mean, if I were "fat," I know that I'd be working out and doing stuff every day. Maybe follow Jared from Subway 🙂 But I'm also saying this having never been fat. Probably easier said than done, right?
