Frequently Asked Questions

Does BMI measure body fat directly?

No. BMI is calculated only from weight and height. It does not measure body fat percentage or body composition directly.

Why might a muscular person have a high BMI?

Because muscle is dense, an athletic individual with significant muscle mass may have a higher weight-to-height ratio without having high body fat.

Is adult BMI calculated the same way for men and women?

The mathematical formula is the same for adult men and women, although body composition and fat distribution often differ.

Can BMI diagnose my overall health?

No. BMI is an initial screening metric, not a comprehensive assessment. Blood pressure, lab results, fitness, lifestyle, and medical history provide a much fuller picture.
