The body measurement often used to assess obesity is body mass index (BMI). BMI is calculated by dividing an individual's weight in kilograms by the square of their height in meters. This measurement helps categorize individuals into different weight statuses: underweight, healthy weight, overweight, and obese. Although BMI is a useful screening tool, it does not directly measure body fat and has limitations, particularly for athletes with high muscle mass. Nevertheless, it remains a widely used indicator for assessing potential health risks associated with obesity.
