What BMI cannot see
BMI only knows weight and height, so it cannot tell muscle from fat. A muscular lifter can read as overweight at low body fat, and someone with little muscle can read as healthy while carrying a lot of fat. It works as a population screen; for your own body composition, the body fat calculator says more.
