What’s BMI?

Whereas it has since been adopted by the World Well being Group (WHO) to categorise people into classes like underweight, wholesome weight, obese, and overweight, its usefulness has been broadly debated.

Athletes like Maher typically fall into the obese or overweight classes of the BMI, due to their spectacular muscle mass. A key drawback with BMI is that it fails to distinguish muscle from fats.
