Understanding waist-to-hip ratio

Waist-to-hip ratio (WHR) is your waist circumference divided by your hip circumference. Unlike BMI, it specifically flags abdominal ("apple-shaped") fat distribution, which carries a higher cardiovascular and metabolic risk than fat carried on the hips and thighs.

Formula

WHR = waist circumference ÷ hip circumference

WHO risk thresholds

Men: WHR above 0.90 indicates abdominal obesity and substantially increased health risk.
Women: WHR above 0.85 indicates abdominal obesity and substantially increased health risk.
