BMI came about in the 1800s when a Belgian mathematician â Adolf Quetelet â reported that body weight across adults varied with the square of height. Itâs worth noting that he derived the formula from studying white, French, and Scottish participants only. In 1972, the weight (kg)/height (m2) formula, was named the Body Mass Index (BMI). BMI classified bodies into âunder weightâ, ânormal weightâ, âoverweightâ, and âobeseâ categories.
So, what is wrong with BMI?
- It is a dated approach that isn't based on great science.
- Itâs a weak measure of population health and was never meant to be used for individual health assessment.
- It does not take into account gender differences.
- It does not consider muscle mass, bone density, physical activity level, or age.
- It does not reflect the health of an individual.
- It can't accurately predict future health outcomes.
- It contributes to weight bias.
Despite BMI being controversial, it continues to be used as a screening tool, which is then used to guide medical care and treatments.
While basing health on weight status has become so normalized, itâs problematic because people in all sized bodies can miss out on appropriate assessment and treatment.
While at times a personâs body weight may play a role in their overall health status, this is greatly overestimated. And even if a personâs weight were negatively contributing to an individualâs health, the question remains: is weight loss sustainable long term? Are weight loss recommendations by health providers actually helping individuals to improve their health long term?
