Body mass index (BMI) is a measure of body fat based on height and weight. It is used to screen for weight-related health problems such as obesity and malnutrition. BMI is calculated by dividing weight in kilograms by the square of height in meters.
BMI is a valuable tool for assessing weight status and health risks. It is simple to calculate and can be used by anyone. BMI was first developed in the 19th century by Adolphe Quetelet, a Belgian astronomer and statistician.
