Limitations of BMI
- It doesn’t measure fat. BMI is just weight and height. It can’t tell muscle from fat. A rugby player and an office worker can have the same BMI for very different bodies.
- It ignores where fat sits. Belly fat (around the organs) is riskier than fat on hips or thighs. BMI can’t see that.
- The same number doesn’t mean the same thing for everyone. Age, sex, and ethnic background change what a given BMI means.
- It struggles in certain groups. Not reliable in pregnancy, in athletes with lots of muscle, in older adults who’ve lost muscle, or in kids unless you use special age/sex charts.
- It leaves out real health clues. BMI says nothing about blood pressure, cholesterol, blood sugar, fitness, sleep, or diet quality.
