Frequently Asked Questions

What is a healthy waist-to-hip ratio?

The WHO considers a WHR below 0.90 for men and 0.80 for women to be low risk for cardiovascular disease.

Why measure WHR instead of just weight?

WHR captures fat distribution — abdominal (visceral) fat carries greater health risk than fat stored in the hips and thighs, even at the same body weight.

How do I measure correctly?

Measure your waist at the narrowest point and hips at the widest point around the buttocks, keeping the tape parallel to the floor.
