- Is BMI an accurate measure of health?
- BMI is a useful screening tool but does not account for muscle mass, bone density, or body composition. Athletes and very muscular people, for example, may show a higher BMI without excess body fat. It is best used as a general guideline, not a diagnosis.
- What do the BMI categories mean?
- Under 18.5 is considered underweight, 18.5-24.9 is the typical range, 25-29.9 is overweight, and 30+ falls into the obese category, per WHO standard classifications.
