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.
