Your question: Is BMI a valid predictor of health risk?

Furthermore, studies have shown that BMI levels correlate with body fat and with future health risks. High BMI predicts future morbidity and death. Therefore, BMI is an appropriate measure for screening for obesity and its health risks.

Is BMI a reliable indicator of health?

Why is BMI a bad indicator of overall health?

Why BMI is not necessarily a good predictor of healthy weight range?

But in recent years, more researchers argue that it’s not the most accurate way to measure body weight. For years, scientists have said that BMI can’t distinguish between fat and muscle, which tends to be heavier and can tip more toned individuals into overweight status, even if their fat levels are low.

What are the disadvantages of BMI?

BMI is also extremely cost-efficient, as calculations only take into account gender, height and weight. But as experts explain, BMI may be too simple. Since muscle weighs more than fat, BMI isn’t accurate in patients with extreme amounts of muscle.
