BMI (Body Mass Index) calculation is a method for estimating body fat based on height and weight. It is used as a screening tool to categorize individuals into weight status groups, such as underweight, normal weight, overweight, and obese.
BMI is a useful tool for healthcare professionals, researchers, and individuals to assess overweight and obesity status, which are significant risk factors for various health issues, including heart disease, stroke, type 2 diabetes, and some types of cancer. Historically, BMI has been widely utilized since its development in the 19th century by Adolphe Quetelet, a Belgian mathematician, statistician, and astronomer.
