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.
