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 extensively 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 have 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 fundamental usefulness is that it corrects for variations in peak when assessing weight.”
So, it’s useful when taking a look at massive populations over time to see if weights are growing or lowering on common, whereas correcting for peak. However, that doesn’t imply it must be utilized on the person degree

“In the case of stopping nutrition-related illness, many consultants are likely to care extra about how a lot adipose tissue [or fat] is sitting across the organs for a protracted time frame,” says Nelson. “That’s the visceral or stomach fats some individuals carry round their midsection.
“Different markers to take a look at embrace proportion of physique fats and waist-to-hip ratio,” says Nelson. “However it’s additionally essential to contemplate weight-reduction plan habits as effectively. Are you getting sufficient protein, fiber, fruits, veggies, and entire grains?”
