Should a 13 year old girl go on a diet?

it is all up to you alot of girl these days weight 6-9 stone and think they are majorly over weight i would say it all depends on youe height and weight and if you really do want to go on a diet make sure you DO NOT STARVE YOURSELF , yes you might loose a few punds but as soon as you start eating again you will put all that weight straight back on and maybe more the best way to do it is to not eat junk food and sugary stuff and eat less nd exercise more :) hope that has helped
