ok im 13 and all my friends say im too thin, i kind of agree but i do eat full meals. but i never really put on loads of weight, i weigh about 39-41 kg and im 160 cm tall and i do do quite a lot of sport at school and i love fruit and veg. What can i do to pun on weight, i no it sound weird that i don't want to loose weight but the opposite, but i just feel really 'unwomanly' and my friend and mum keeps on commenting, im scared cause im going to my grand parents house in france and they always say that im too thin. its unfair because my mum is over weight and i think i just dont want to end up like her. What do i do? HELP thank you what ever you say
