It's not that unusual to weight less than girls really. You have to do some sports to develop muscles (more than you need for just moving around). Guys naturally develop more muscles than girls, but they also hit and complete puberty later. And before puberty it's almost equal for both as far as body shape goes.
I remember that at school quite a few guys' voices hadn't broken yet and there already were girls with clearly defined hips/boobs, not fat ones, just already pretty developed. You still get weight from that (even if it's not as much as from muscles), so they might well weighted more.
A word of warning about gaining a lot of weight, if you're in your growth spurt. Don't go overboard, the extra weight can mess up your knees during that time (even just growing too fast can do that to you).
Anyway, I'd suggest good meals (have some eggs for breakfast, eat meat, enough vitamin intake) and a more general endurance and muscle building sport (running, swimming or some team sports) rather than protein shakes and the gym.
