BMI remains a useful screening tool, but diagnosis and treatment planning improve when clinicians also assess abdominal adiposity, comorbidity, and functional impact.
What BMI misses
- BMI does not distinguish fat from muscle.
- Visceral and ectopic fat are more closely linked to cardiometabolic risk.
- A person with a 'normal' BMI can still carry clinically important adiposity.
A simple additional measure
Waist-to-height ratio adds a practical marker of abdominal adiposity. A ratio above 0.50 suggests increased cardiometabolic risk and should be interpreted alongside BMI, comorbidities, physical function, and the broader clinical assessment.
A practical pathway
- Screen with BMI, waist circumference, and waist-to-height ratio.
- Stratify cardiometabolic and functional risk.
- Personalize lifestyle and pharmacologic care.
- Track metabolic markers and health impact, not weight alone.
