Why fat distribution matters
Where you store fat matters as much as how much. Abdominal (apple-shaped) fat carries higher health risk than hip and thigh fat, which the ratio captures.
Frequently asked questions
What is a healthy waist-to-hip ratio?
The WHO considers below 0.90 for men and 0.85 for women lower risk. Higher ratios indicate more abdominal fat and greater cardiometabolic risk.
Where do I measure waist and hips?
Measure the waist at its narrowest point (around the navel) and the hips at their widest point around the buttocks, keeping the tape level.
