Understanding WHtR
WHtR compares your waist circumference to your height, offering a quick proxy for central fat distribution. It’s often a better indicator of cardiometabolic risk than BMI alone.
- Simple formula: Waist ÷ Height (use the same units).
- Central obesity marker: Focuses on abdominal fat, a key risk driver.
- Screening tool: Use alongside BMI and body fat estimates.
Typical Categories (Adults)
- < 0.40: Underweight/lean
- 0.40–0.49: Healthy
- 0.50–0.59: Increased risk
- ≥ 0.60: High risk
Limitations
- Not a diagnosis: It’s a screening indicator, not a medical verdict.
- Measurement error: Small tape errors can shift categories.
- Age considerations: Cutoffs vary for children; use pediatric charts.
Action Steps
- Measure at the navel: Take waist at the level of the belly button, relaxed.
- Track trends: Combine with weight and body fat tracking.
- Lifestyle basics: Nutrition quality, resistance training, and sleep.
Important: WHtR is an estimate for educational use. For medical advice, consult a qualified professional.
