How Much Should A 50 Year Old Woman Weigh That Is 5'1"?

I have always heard that a good formula is 100 pounds for 5ft, and 5 additional pounds per inch, so it would be 105 pounds for you. I don't think age has anything to do with it. Younger people have faster metabolisms and usually weigh less than older individuals. I think a more accurate measure of healthy weight is now considered a BMI, or Body Mass Index.

the other answers are the reason why women have poor self images. An average 5'1" , 50 year old woman who has most likely had a few children should realistically weight between 120 and 140, depending on their build. 100 pounds? I don't know ONE. Even my skinniest friend weighs 110.
