Why South Asian cutoffs matter
South Asians can accumulate more visceral fat at lower BMIs than many other populations. That means a person can look slim, have a normal BMI, and still carry abdominal fat linked with diabetes, high blood pressure, and dyslipidaemia. Waist-based tools are useful because they focus more directly on central fat distribution.
That is why waist size and waist-to-height ratio matter so much in Pakistani screening conversations. A waist above 90 cm in men or 80 cm in women is already worth paying attention to.
WHtR vs WHR
Waist-to-height ratio is usually the simpler screening target: keep waist below half your height. Waist-to-hip ratio adds body-shape context by comparing abdominal size with hip size. When both are elevated, concern about abdominal obesity is stronger.
How to measure correctly
Measure waist midway between the lower rib and top of the hip bone. Measure hip at the widest point of the buttocks. Measure height without shoes. Use the same unit for all three values and keep the tape snug, not tight.
