Why BMI Matters for Your Health
BMI helps determine your risk of chronic diseases such as diabetes, heart disease, and hypertension. It’s a good first-step diagnostic tool to evaluate whether you need lifestyle changes, medical advice, or weight management plans.
Limitations of BMI
While BMI is widely accepted, it has some limitations. It doesn’t differentiate between fat and muscle mass. Therefore, athletes or muscular individuals might have a high BMI but low fat percentage. It’s important to combine BMI with other health metrics for a holistic view.
