BMI is a rough screening number for adults. It doesn't tell muscle from fat, and it isn't meant for children, pregnancy or athletes. Talk to a doctor about your own health.

Frequently asked

What is a healthy BMI?

For most adults, 18.5 to 24.9. Under 18.5 is underweight, 25 to 29.9 overweight and 30 or more obese.

Is BMI accurate?

It is a quick screening number. It does not tell muscle from fat, so very muscular people can score high. It is not for children or pregnancy.
