Combining body mass index with other measurements and tests would lead to better care and outcomes, experts say

An alternative to BMI for diagnosing obesity could prevent misdiagnosis in millions of people worldwide, according to doctors who found it more accurately distinguished healthy people from those with harmful excess body fat.

Medical experts have long considered body mass index a blunt instrument for defining obesity, leading to concerns that substantial numbers of people with excess body fat are missed while others who are healthy are wrongly diagnosed.

The new approach, which combines BMI with other body measurements and organ function tests, suggests BMI alone misses obesity in 5-9% of adults, while wrongly diagnosing the condition in as many as 3%.

“This misclassification can account for tens of millions of people, so the inaccuracy of BMI is a big problem at scale and also for individuals,” said Francisco Rubino, a professor of metabolic and bariatric surgery at King’s College London.

I've literally never seen a single person actually claim that about themselves. I've seen plenty of people point out the flaw of just using weight and height to diagnose others as overweight or obese, which is supported by literally all of the evidence in front of you. But I've never seen a conversation where someone's BMI somehow came up and they claimed that actually they're perfectly fit and it's a problem with BMI as a measurement. That's just not a thing that happens outside of the fantasies of fatphobic weirdos
