My BMi is 20.8 I'm 14 and I'm a female is this good or bad? I really want to lose 10 kilo's I weigh 50 and I'm 155 cm tall!! HELP!! :confused:

You are the perfect weight for your height and do not need to change at all. If you try to lose all that weight you will damage yourself physically and emotionally. Why do you feel you need to lose weight?

I agree with tempelane that you are perfect for your height.

Do you exercise? You may be feeling that since you aren't toned that you are "fat".
