What is a healthy waist-to-hip ratio?

According to the WHO, a healthy waist-to-hip ratio is below 0.90 for men and below 0.85 for women. Values above these thresholds are associated with increased cardiovascular disease risk, type 2 diabetes, and metabolic syndrome.

Is waist-to-hip ratio better than BMI?

Waist-to-hip ratio is often considered a better predictor of cardiovascular risk than BMI, because it directly measures abdominal fat distribution. Visceral fat (fat around organs) is more metabolically harmful than subcutaneous fat. However, using both metrics together gives the fullest picture.

Waist-to-Hip Ratio — Complete Guide

Waist-to-hip ratio (WHR) measures the ratio of your waist circumference to your hip circumference. It is one of the best predictors of cardiovascular disease, type 2 diabetes, and metabolic syndrome — sometimes superior to BMI — because it specifically captures abdominal fat distribution, the most metabolically harmful type of body fat.

WHO WHR Thresholds

Sex	Low Risk	Moderate Risk	High Risk
Men	Below 0.90	0.90 – 0.95	Above 0.95
Women	Below 0.80	0.80 – 0.85	Above 0.85

Why WHR Matters More Than Weight

Two people can weigh the same and have the same BMI, yet carry their fat in completely different places. A person who stores fat around the abdomen (apple shape) faces significantly higher cardiovascular risk than someone who stores fat around the hips and thighs (pear shape), even at the same body weight.

Visceral fat — the deep abdominal fat measured indirectly by waist circumference — is metabolically active. It releases inflammatory cytokines, disrupts insulin signalling, and correlates strongly with hypertension, dyslipidaemia, and type 2 diabetes. Subcutaneous fat (hips and thighs) does not carry the same risk.

How to Reduce Waist Circumference

Calorie deficit: Visceral fat responds well to a sustained 300–500 kcal/day deficit. Use our calorie calculator to find your target.
Aerobic exercise: Zone 2 cardio (3–4× per week) specifically targets visceral fat, independent of weight loss.
Reduce refined carbohydrates and alcohol: Both drive visceral fat accumulation independently of overall calorie intake.
Sleep 7–8 hours: Chronic sleep deprivation raises cortisol, which specifically promotes abdominal fat storage.
Manage stress: Elevated cortisol from chronic stress drives the same abdominal fat accumulation pathway.

Frequently Asked Questions

The WHO defines a healthy WHR for women as below 0.80. Values of 0.80–0.85 represent moderate risk, and above 0.85 is high risk. Women naturally have lower WHR than men due to greater hip fat distribution, which is less metabolically harmful than abdominal fat.

For men, a WHR below 0.90 is considered low risk by the WHO. Values of 0.90–0.95 are moderate risk, and above 0.95 is high risk. Men tend to carry more visceral (abdominal) fat than women, which is why men face higher cardiovascular risk at equivalent BMI levels.

For men: measure at the navel level, with the abdomen relaxed (not sucked in). For women: measure at the narrowest point between your lower ribs and hip bones. Use a flexible, non-elastic tape measure. Take the measurement after exhaling gently. Do not compress the skin. Take two readings and average them.

Yes — and visceral fat (which drives waist circumference) responds particularly well to aerobic exercise. Studies show that 150–300 minutes per week of moderate-intensity aerobic exercise reduces waist circumference by 2–4 cm even without weight loss (you may gain muscle while losing visceral fat). Spot reduction (losing fat in a specific area through targeted exercises) is a myth — overall fat loss through diet and exercise reduces waist circumference.
