Researchers say they have a better way to measure weight than BMI
Study finds BMI is a ‘deeply flawed’ way to measure weight
- A new study from University of Florida Health questions the effectiveness of Body Mass Index (BMI) as a standard for defining obesity and predicting health outcomes.
- Lead author Dr. Arch Mainous stated the study found BMI to be "deeply flawed" and unable to predict the risk of future death, unlike direct body fat measurements.
- The research proposes bioelectrical impedance analysis (BIA), an inexpensive method that directly measures body fat, as a significantly more accurate alternative to BMI.
- The study of 4,252 individuals revealed a strong link between high body fat (measured by BIA) and increased mortality risk, a correlation not observed when using BMI.
- Critics note BMI's limitations, including its inability to differentiate between muscle and fat mass and its failure to account for variations across different demographics.
