Why isn't a BMI (Body Mass Index)a perfectly reliable way to estimate your health?

Question

Quizplus · Accepted Answer

BMI only takes into account height and weight, but not variations in muscle mass, bone density, and distribution of fat. This can result in individuals with high muscle mass being classified as overweight or obese, despite having a healthy body composition. Additionally, studies have shown that BMI is not always a reliable indicator of the relative amount of body fat and the associated risk of illness and death.
