Re: Underweight?
Waist circumference is an other measure that can be used to determine if someone is not healthy. Women should have a wc of less than 80cm and men less than 90cm. Body frame does make a difference; there are difference ways to determine ones frame size which you cant determine on your own because you have to be trained to do so accurately. I guess for an estimate BMI and WC are two good measures for most individuals.
