What BMI doesn't tell you
BMI is weight divided by height squared. It doesn't tell muscle from fat, so athletes can score high, and it isn't meant for children, teenagers or pregnancy. Some health services, for example in India and other parts of Asia, use lower cut-offs (23 and 27.5). Treat it as a starting point and talk to a doctor about your health.
