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, because of their spectacular muscle mass. A key downside with BMI is that it fails to distinguish muscle from fats.
“BMI is only a comparability of peak to weight, nothing extra,” Nelson says. “It doesn’t keep in mind how a lot muscle an individual has, and by itself, it doesn’t say something about well being, way of life, or particularly price. BMI’s principal usefulness is that it corrects for variations in peak when assessing weight.”
So, it’s useful when taking a look at giant populations over time to see if weights are rising or reducing on common, whereas correcting for peak. However, that doesn’t imply it must be utilized on the person stage

“Different markers to have a look at embrace share of physique fats and waist-to-hip ratio,” says Nelson. “Nevertheless it’s additionally vital to think about food plan habits as properly. Are you getting sufficient protein, fiber, fruits, veggies, and complete grains?”
