What is BMI and how should you use it?

BMI, or Body Mass Index, is a quick screening tool that compares your weight to your height. It can help you understand whether you are in an underweight, normal, overweight, or obesity range.

BMI is useful for a fast overview, but it does not measure body fat directly and it cannot distinguish between fat mass and muscle mass. Athletes and very muscular people can have a high BMI without having excess body fat.

Use BMI as a starting point, not as a diagnosis. For a more complete picture, combine it with waist measurements, body fat estimates, lifestyle data, and your long-term health goals.
