I get fat easily,excercise helps a bit but not much and I don't eat that much either. :-/
Some of the skinny boys in my class excercise a bit with soccer and footbal etc but they eat tons of chocolate and crips and energy drinks,its strange.
Dont you play anything?
I do,but it doesn't help one bit.

Nah,I think some people just stay skinny,my mom for example can eat tons of icescream and food etc for a week and only add maybe 1 KG...
