Limitations of BMI
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 without excess fat. For a more comprehensive health assessment, consult with a healthcare professional.
Why Monitor Your BMI?
Maintaining a healthy BMI can help reduce the risk of weight-related health problems such as heart disease, high blood pressure, type 2 diabetes, and certain cancers. Regular BMI checks can help you track your weight status over time and make informed decisions about your health.
