Bmi calculator how does it work

If you want to calculate your BMI, try our healthy weight calculator. BMI takes into account natural variations in body shape, giving a healthy weight range for a particular height. As well as measuring your BMI, healthcare professionals may take other factors into account when assessing if you're a healthy weight. Muscle is much denser than fat, so very muscular people, such as heavyweight boxers, weight trainers and athletes, may be a healthy weight even though their BMI is classed as obese.

Your ethnic group can also affect your risk of some health conditions. For example, adults of South Asian origin may have a higher risk of some health problems, such as diabetes, with a BMI of 23, which is usually considered healthy.
