This always bugs me, girls always say about skinny boys, i weigh 8 stone, 5' 10" and I'd be willing to bet I eat more junk food than majority of fat people. Being skinny isn't hard work for me, but I think some people don't understand just like how people can't help being fat, neither can people that are skinny. I once made it up to 10 stone with the help of some prescribed steroids by the doctor, then I carried on eating this high intake diet and I lost it all.
Also you know being skinny is bad when you have to wear size 8 womens jeans because mens skinnys look like slim fits.
