1. What is Waist-to-Height Ratio?

The Waist-to-Height Ratio (WHtR) is a simple anthropometric measure that compares waist circumference to height. It's considered a better predictor of health risks than BMI, as it directly measures central obesity.

2. How Does the Calculator Work?

The calculator uses the WHtR formula:

Where:

• Waist Circumference — Measured at the midpoint between the lower rib and the iliac crest
• Height — Measured without shoes

Interpretation:

• WHtR < 0.5 — Low risk (healthy range)
• WHtR 0.5-0.6 — Moderate risk
• WHtR > 0.6 — High risk

3. Importance of WHtR

Details: WHtR is a better predictor of cardiovascular risk and metabolic syndrome than BMI. It accounts for both central obesity (waist) and body size (height), making it applicable across different ethnic groups.

4. Using the Calculator

Tips: Measure waist circumference at the narrowest point between ribs and hips while standing. For height, measure without shoes. Enter values in centimeters for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why use WHtR instead of BMI?
A: WHtR better accounts for body fat distribution and is more accurate at predicting health risks, especially in non-overweight individuals with central obesity.

Q2: Is the ratio different for men and women?
A: The same ratio applies to both genders, though women naturally tend to have higher ratios due to different fat distribution.

Q3: How often should I measure my WHtR?
A: Every 3-6 months is sufficient for tracking changes, unless you're actively trying to lose weight.

Q4: Are there limitations to WHtR?
A: It may be less accurate in very tall or short individuals, pregnant women, and those with certain medical conditions affecting body shape.

Q5: What's a good target WHtR?
A: Aim for below 0.5 for optimal health, though gradual improvement is beneficial even if you don't reach this target immediately.
