Why Waist-to-Height Ratio Matters More Than BMI

Waist-to-height ratio (WHtR) is gaining recognition as one of the best single indicators of cardiovascular and metabolic health. The simple rule: your waist circumference should be less than half your height. If your waist is 80 cm, you want to be taller than 160 cm — or reduce your waist.

Research consistently shows WHtR outperforms BMI for predicting heart disease, type 2 diabetes, hypertension, and stroke risk. This is because it directly reflects abdominal (visceral) fat — the most metabolically dangerous type.

How to Measure Your Waist Correctly

Measure at the narrowest point between your lowest rib and your hip bone, typically just above the navel. Don’t suck in your stomach. Measure in the morning before eating for the most consistent results.

Interpreting Your Result

A ratio below 0.4 is very slim, 0.4–0.5 is healthy, 0.5–0.6 is overweight with increased risk, and above 0.6 is high risk. Aim to stay below 0.5 regardless of your weight or BMI.

FAQ

Is this measurement different for men and women? Slightly — women naturally carry more fat around the hips, but the 0.5 threshold applies to both sexes for health risk purposes.
