What Is Body Mass Index (BMI)?
Body Mass Index (BMI) is a screening measure calculated from a person’s weight and height. For adults, BMI is commonly grouped into these categories:
- Underweight: Below 18.5
- Normal weight: 18.5 to 24.9
- Overweight: 25 to 29.9
- Obesity: 30 or above
Is BMI a Complete Measure of Health?
No. BMI does not directly measure body fat or distinguish muscle from fat. Age, body composition, and other health factors can affect how a result should be interpreted.
