Body Mass Index (BMI) is a numerical value calculated from your weight and height. It provides a simple way to categorize a person as underweight, normal weight, overweight, or obese.
While BMI is a useful screening tool, it has some limitations. It doesn't directly measure body fat and doesn't account for factors like muscle mass, bone density, or overall body composition. Athletes with high muscle mass may have a high BMI but not have excess body fat. Older adults may have more body fat than younger adults with the same BMI.
For a more comprehensive health assessment, consult with a healthcare professional.
