What is BMI?
Body Mass Index compares your weight with your height to estimate whether your weight falls within a generally recognised range for adults.
Is BMI accurate?
BMI is useful as a screening tool, but it does not measure body fat directly and should be considered alongside other health information.
Does muscle affect BMI?
Yes. People with significant muscle mass can receive a high BMI result even when their body-fat level is not high.
Is BMI different for men and women?
The adult BMI formula and category thresholds are the same for men and women, although body composition can differ.
