Body mass index (BMI) and body fat percentage are measures of body composition that can indicate overall health and risk of chronic diseases. BMI is calculated by dividing weight in kilograms by the square of height in meters (kg/m2). Body fat percentage is the percentage of total body weight that is made up of fat.
Both BMI and body fat percentage are important measures of health. BMI is a good indicator of overall weight status, while body fat percentage provides more information about the distribution of fat in the body. High levels of body fat, especially in the abdominal area, are associated with an increased risk of heart disease, stroke, type 2 diabetes, and some types of cancer.
The concept of BMI was first developed in the 19th century by Belgian statistician Adolphe Quetelet. He used it as a way to compare the weights of different populations. The first widely used body fat percentage equation was developed in the 1960s by a group of researchers at the University of California, Berkeley. Today, BMI and body fat percentage are used by healthcare professionals around the world to assess body composition and health risk.
