Understanding Body Mass Index (BMI)

Body Mass Index (BMI) is a screening metric established by the World Health Organization (WHO) to evaluate body mass relative to height. While BMI does not directly measure body fat percentage or differentiate between muscle mass and fat mass, it provides an invaluable population-level risk assessment for cardiovascular conditions, hypertension, and diabetes.

Frequently Asked Questions

Does BMI apply to athletes and bodybuilders?

BMI may overestimate body fat in athletes or individuals with dense muscular builds because muscle tissue is denser than fat tissue. Muscular individuals should combine BMI with waist circumference or body fat calipers.
