Your ratio vs risk thresholds

LowModerateHigh

Your waist-to-hip ratio compares fat stored around your midsection to fat around your hips. Because abdominal (visceral) fat is more strongly linked to heart disease and diabetes than fat elsewhere, WHR is a simple but meaningful health indicator — sometimes more predictive than BMI.

Recommendations

  • If you're in a higher-risk band, reducing waist circumference through fat loss and regular activity lowers risk.
  • Track waist measurement over time — it responds to lifestyle changes and reflects visceral fat.

Watch out

  • WHR is a screening tool, not a diagnosis. Discuss elevated results and overall risk factors with a healthcare professional.

Pro tips

  • Measure your waist relaxed after a normal exhale — don't suck in.
  • Combined with waist circumference alone, WHR gives a fuller picture than either metric solo.

Where you store fat matters as much as how much you carry. Waist-to-hip ratio is a fast, tape-measure health check that highlights risky abdominal fat.

Why fat distribution matters

Visceral fat around the organs is metabolically active and strongly tied to heart disease and type 2 diabetes. A higher waist relative to hips signals more of this fat — which is why WHR carries independent predictive value.

Interpreting your number

Risk thresholds differ by sex. Use the category as a prompt: an elevated ratio is a cue to prioritise fat loss and activity, and to discuss your broader risk profile with a professional.

Frequently asked questions

For men, below 0.90 is low-risk; for women, below 0.80. Ratios above ~1.0 (men) or ~0.85 (women) indicate higher cardiovascular and metabolic risk.

For predicting heart-disease risk, WHR can outperform BMI because it captures fat distribution — abdominal fat is more harmful than fat on the hips and thighs.

Measure your waist at its narrowest point (usually the navel) and your hips at the widest point of the buttocks, keeping the tape level and snug while relaxed.
