Understanding BMI for Women
What is BMI?
BMI is a measurement of a person’s leanness or corpulence based on their height and weight, and is intended to quantify tissue mass. It is widely used as a general indicator of whether a person has a healthy body weight for their height. The value obtained from the calculation of BMI is used to categorize whether a person is underweight, normal weight, overweight, or obese.
BMI Formula
BMI = weight (kg) / height² (m²)
or
BMI = 703 × weight (lbs) / height² (inches²)

Limitations of BMI for Women
