Possible for a 13 year old girl to lose weight in a month?

Is it possible for a 13 year old girl to lose weight and become thin in weeks or one month maximum??

It's not advisable because your body is still growing. During puberty you might weigh a few extra pounds, but by the time you get to 15 or 16, your body is more like a woman's body and the puppy fat, if any, will be gone. Don't try to lose weight at this age.

why?
and I said a 13 year old girl!! (she's my friend)
she weighs 88,7 !!'
and mom told me she could but I can't believe it!

If she's that heavy at 13, she should see a doctor. There's more problems going on here than overeating. She is probably very unhappy with herself. The faster she loses it, the faster she will gain it back. She needs to lower her calories and increase her activities.

yeh, starve your self you wont die and you will lose loads of weight, only weak people eat, strong people dont! x

don't have you friend do what babeeyyblonde said because when you starve urself you can get very sick from it. so make sure she doesn't do that because I know someone who did that and they went to the hospital because they were so sick. if we were supposed to starve ourselves then we wouldn't have food.

but, its a survival thing from our ancestors, if you do it right and starve urself just the right amount ull lose a lot of weight and feel good about urself. as much as you can.

but she doesn't look fat at all!!! __height like me (163,7)
if you see her you'll think she weighs in 60's!!
ya it's because she's tall (it's not showing) but she's fine with how she looks!!
but when she wears something tight you'd rather look at yourself in the mirror instead of looking at her!!
