Worth Knowing
Waist-to-height ratio has gained favor over BMI as a screening tool because it directly targets central fat, the kind most associated with metabolic risk, and it needs no age or sex adjustment. The rule of thumb is simple and memorable: keep your waist to less than half your height. Because it uses a ratio rather than absolute weight, it works across a wide range of body sizes, though it still can't distinguish muscle from fat the way imaging can.
