Why Distribution Beats Amount
Visceral fat around the organs behaves differently from subcutaneous hip fat: it releases inflammatory cytokines and free fatty acids directly into the portal circulation that feeds the liver.
That's the mechanism behind the finding that waist-to-hip ratio predicts heart disease and diabetes better than total weight alone, and why two people of identical BMI can carry very different risk.
Measuring It Properly
Waist: the narrowest point, usually just above the navel. Hips: the widest point across the buttocks. Stand relaxed, tape horizontal, measure after a normal exhale, not over clothing.
Divide the two in the same units. A 90 cm waist with 100 cm hips gives 0.90, right at the male cut-off and above the female one.
Using the Number
Trend it quarterly alongside weight. WHR improves as visceral fat shrinks, often before the scale moves, which makes it a motivating early signal during fat loss.
Combine with BMI or body-fat percentage: WHR tells you where, the others tell you how much. Together they're a genuinely complete picture.

FAQ
What is a good waist-to-hip ratio?
Below 0.90 for men and 0.85 for women, per WHO cut-offs.
Why does waist-to-hip ratio matter more than weight?
It captures abdominal fat, which drives inflammation and metabolic disease, total weight can't show where fat sits.
How do I measure my hips correctly?
Feet together, tape horizontal around the widest point of the hips and buttocks, relaxed.
