WHAT THIS DOES NOT DO

BMI does not distinguish muscle from fat. A muscular person can register as overweight while being metabolically healthy.
WHO and several national bodies recommend LOWER thresholds for people of South Asian, Chinese and other Asian ancestry — overweight from about 23 and obesity from about 27.5 — because cardiometabolic risk rises at a lower BMI. This matters for much of the UAE population.
BMI says nothing about where fat is stored, and visceral fat carries the greater risk.
