what is BMI?
The body mass index (BMI), or Quetelet index, is a controversial statistical measurement which compares a person's weight and height. ( source link : WIKIPEDIA )
The tool doesn't really measure fat percentage in your body, but useful to estimate a healthy body weight based on how tall a person is.
