The waist-to-hip ratio indicates your probable health risks. Research shows that people with apple-shaped bodies, with more weight around the waist, face more risks than those with pear-shaped bodies that carry more weight around the hips.

It's calculated by dividing waist circumference at its narrowest point by hip circumference at the widest point. It is a simple and useful measure of fat distribution.

Ratios above 0.80 for women and 0.95 for men are associated with obesity and are linked to greater risk for health complications and diseases.
