BMI has real limitations
BMI was invented in 1832 by Adolphe Quetelet for population-level statistics, not individual health assessment. It cannot distinguish muscle from fat, and doesn't account for bone density, age, sex, or body composition. Athletes and people who carry more muscle may have a "high" BMI with low body fat. The NHS recommends using BMI alongside waist circumference for a fuller picture.
