The flaws of BMI as a measure of obesity

BMI, or Body Mass Index, has been used for decades as an international standard to determine healthy weights. However, it does not measure body fat and overlooks factors such as age, sex, and race that affect a person's health at a given weight. Studies have shown that individuals with similar BMI values can have different levels of body fat, and being in the overweight category does not necessarily indicate higher health risks. BMI's simplicity and cost-effectiveness have kept it prominent, but experts argue that it should be used as a screening tool rather than a sole diagnostic tool.
