How it works
Fat stored around the abdomen (visceral fat) is closely linked to insulin resistance, high blood pressure and heart disease. Waist-to-height ratio captures this better than BMI, and the message is simple for everyone: keep your waist to less than half your height.
A ratio of 0.5–0.59 means increased risk and 0.6 or above means high risk. This measure is especially useful for South Asians, who often carry abdominal fat even at a normal weight.
