Why BMI Matters
BMI is a quick screening tool used by healthcare professionals worldwide. While it does not measure body fat directly, it correlates with more direct measures of body fat. A BMI in the normal range (18.5 to 24.9) is associated with lower risk for conditions like heart disease, type 2 diabetes, and high blood pressure.
Keep in mind BMI has limitations — it does not distinguish between muscle mass and fat, and results may differ for athletes, elderly individuals, and pregnant women. Always consult a healthcare professional for personalized advice.
