Okay, so I'm 15, female, and I'm very short and only weigh 6 and half stone! I always get comments made at school saying how 'skinny' I am and some call me annorexic! I find it hard to gain weight, but if anyone has any tips on what kind of foods I should be aiming for it would be much appreciated!

Quite frankly if you are eating normal then dont worry about it. Your body is and has gone through massive changes. What will happen later is that your body will settle into where you should be. If you start over eating now it could put you at risk later for problems that are unseen at this time. Your best bet is to just deal with it and so long as your feeling well let others deal with what they have. Its not for them that you live and breath it is for you and you alone.

Wait a few years... you will probibly be begging for a way to LOSE weight, when your metabolism slows down... and it does for everyone as you get older.
