Deep Dive: Why WHR Matters
The Science of Fat Distribution
While Body Mass Index (BMI) measures total body fat, the Waist-to-Hip Ratio (WHR) identifies where that fat is stored. Research consistently shows that “visceral fat” (fat stored around the abdominal organs) is more metabolically active and poses a greater risk to your health than fat stored in the hips or thighs.
Apple vs. Pear Body Shapes
Apple Shape: Higher WHR. Indicates more weight around the middle. Associated with higher risks of hypertension, type 2 diabetes, and cardiovascular disease.
Pear Shape: Lower WHR. Indicates more weight around the hips and thighs. Generally considered a healthier fat distribution pattern.
How to Measure Like a Pro
The Waist Measurement
Find the midpoint between your bottom rib and the top of your hip bone. Breathe out normally and measure without pulling the tape too tight. This is usually just above the navel.
The Hip Measurement
Stand with your feet together. Wrap the tape around the widest part of your buttocks. Ensure the tape is perfectly level (parallel to the floor) for the most accurate reading.

| Moderate Risk | 0.91 – 0.99 | 0.81 – 0.84 | Transitioning |
| High Risk | 1.00 or above | 0.85 or above | Apple Shape |
