Why WHtR? Research shows waist-to-height ratio is a better predictor of cardiovascular risk than BMI alone. It accounts for central adiposity — the dangerous fat stored around organs.

How to measure: Measure waist at the narrowest point (usually at navel level) while standing relaxed. Use a flexible tape measure snug against skin without compressing.
