What is the ideal body weight and measurement for my seventeen year old cousin?

Question

She's loosing weight and is not sure of how much she has to loose. Right now, she weighs about 156 lbs.

Answer 1

It all depends on how tall she is. The scale goes like this.

for every inch a female is over 5 Ft. She should be 5-6 Lbs. Over 100Lbs.

So if she is 5"5 she should weigh 125-130
If she is 5"8 then around 145-150

I think you get the picture.

Answer 2

Well, how tall is she? Does she have a small, medium or large frame, is she very athletic, we can't answer this question without more information. TIA : )
