What is BMI?

Body Mass Index (BMI) is a measure that relates weight to height to assess whether a person has a healthy weight. It was developed by Adolphe Quetelet in the 19th century and is used by WHO as a population health indicator.

How is it calculated?

BMI is calculated by dividing weight in kilograms by height in meters squared: BMI = weight (kg) / height² (m). For example, a person weighing 70 kg and 1.75 m tall has a BMI of 22.9.

BMI Limitations

BMI doesn't distinguish between muscle mass and fat, so it may overestimate fat in athletes or underestimate it in the elderly. It doesn't consider body fat distribution or other health factors.
