Waist-hip ratio or Waist-to-hip ratio (WHR) is the ratio of the circumference of the waist to that of the hips.
It measures the proportion by which fat is distributed around the torso. Measuring body size and composition or body shape. A pear shape means that fat builds up on your hips, apple shape means fat gravitates to your waist and upper torso, or avocado shaped is somewhere in between.
It's important to know what shape you have because an avocado- or apple-shaped body can put you at risk of certain weight-related health conditions, including heart disease, stroke, and diabetes.
Measure your waist (through the belly button) and the hip (at the widest point)
Divide waist measurement, by hip measurement: to give your ratio.
