What is BMI?
BMI (Body Mass Index) estimates body fat using height and weight. A common healthy range for adults is 18.5 – 24.9.
- Underweight — below 18.5
- Normal — 18.5 to 24.9
- Overweight — 25 to 29.9
- Obese — 30 and above
BMI is a screening tool, not a diagnosis. Muscle mass, age, and other factors also matter. For personal advice, talk with a healthcare professional.
