I'm not sure whether you are bothered by your weight. But constant sitting in front of computer and playing games doesn't contribute much to my build. Just now I heard of someone tilt body when playing tilt games. Do you have any game with weight-losing function or any good suggestion on the way to play? (If you think this is a stupid thread, I will call for mods' help to delete it.)
Just play Angry Birds. It encourages you not to become a fat pig or else many clorful birds will hurl at you with all their might.
I suggest getting a weight scale app on your iPhone and then steppin on your iPhone to check ur weight
