4 outletsA new definition of obesity, distinguishing '' (with metabolic or functional impairment) from '' (excess fat without current impairment), has been validated across multiple in a Nature study. The definition uses objective health measures beyond and is shown to be a better predictor of obesity-related outcomes, offering a more precise diagnostic tool than BMI alone.
The claim is directly from a peer-reviewed study published in Nature (DOI: 10.1038/s41586-026-11237-5), a primary source. The validation across global cohorts suggests robust evidence, though the exact definition and performance metrics are detailed in the paper itself. Search results confirm the study's existence and related work on clinical obesity definitions.
The paper was published in 2026 (as per the DOI and search results showing an August 2026 article), so this is genuinely new research, not resurfaced material.
