Almost 70% of US Adults Would Be Deemed Obese Based on New Definition, Study Finds (theguardian.com)

(Wednesday October 15, 2025 @05:22PM (msmash) from the how-about-that dept.)


Almost 70% of adults in the US would be [1]deemed to have obesity based on a new definition, research suggests. From a report:

> The traditional definition of obesity, typically based on having a body mass index (BMI) of 30 or greater, has long been contentious, not least as it does not differentiate between fat and muscle.

>

> In an effort to tackle the issue, in January medical experts from around the world called for a new definition to be adopted. This would encompass people either with a BMI greater than 40; or those with a high BMI and at least one raised figure for measures such as waist circumference, waist-to-hip ratio, or waist-to-height ratio; or those with two such raised figures regardless of BMI; or those with direct measures of excess body fat based on scans.

>

> In addition, they said obesity should be split into two categories: clinical obesity -- where there are signs of illness -- and pre-clinical obesity, where there are not. Now research suggests the revamped definition could result in a dramatic rise in the prevalence of obesity among adults in the US.

We could live in a world where the vast majority of people have some type of identifiable mental illness, but isn't impaired or debilitated by it.

Statistically, we can look at populations with some identify condition. Such as obesity, hypertension, etc and make a statistical connection to likely outcomes in those groups. Even if an individual is not impaired or at put at risk by their obesity, a significant number of people in the same group are at an elevated risk if not already impaired.

Technically these drugs do change your diet and habits - that's what most of the weight loss comes from. Eating poorly for a while causes a mass die-off of bacteria in your digestive tract that helps with digesting healthy and fiber-rich foods. Those same bacteria actually release their own GLP-1 agonists. We can probably do better than these medications but they aren't a cheap gimmick either - these are drugs that try to make your body function as if it doesn't have a metabolic disorder and it drives be
