Its prevalence continues to rise worldwide, imposing substantial burdenson health systems and societies. At the same time, remarkable advances have been made in recent years, with the development of highly effective pharmacotherapies acting on receptors related to glucagon-like peptide-1 (GLP-1) and with the refinement of bariatric and metabolic surgery. These breakthroughshave transformed the therapeutic landscape and highlighted the importance of precise disease definitions to identify patients most likely to benefit from intervention.  \nA NEW FRAMEWORK: THE CONCEPT OF “CLINICAL OBESITY”In light of these developments and broader challenges, an international commission convened by The Lancet Diabetes & Endocrinology recently proposed the concept of “clinical obesity” as a means of refining how obesity should be defined and addressed1. They argued that defining obesity solely by body mass index (BMI) is inadequate, as BMI fails to capture the heterogeneous health risks associated with excess adiposity. Instead, the  \nCorrespondence Wataru Ogawa Tel.: +81-78-304-6046  \nFax: +81-78-382-2080  \nE-mail address: [ogawa@med.kobe-u.ac.jp](ogawa@med.kobe-u.ac.jp)  \nReceived 24 September 2025; revised 30 September 2025; accepted 1 October 2025  \nreport emphasized the need to consider both fat distribution and the functional consequences of adiposity.  \nWithin this framework, excess adiposity is divided into two categories: preclinical obesity, where there is excess adiposity without demonstrable impairment, and clinical obesity, where adiposity has already produced organ or tissue dysfunction and/or limitations in ageadjusted daily living activities. By introducing these categories, the authors sought to clearly distinguish between individuals at risk and those already experiencing disease due to obesity (Figure 1).  \nThe commission also stressed that this new framework should lay the foundation for a future international consensus. Implementation, they suggested, will require global harmonization of definitions and approaches, while also allowing regional adaptation to account for country-specific epidemiology, health systems, and resources. Thus, the proposal represents an aspirational step intended to guide future clinical practice and policy. At this stage, however, it remains primarily a conceptual framework, and its translation into tangible outcomes will depend on subsequent international and regional efforts.  \nTHE JAPANESE CONCEPT OF“OBESITY DISEASE (HIMAN-SHO)”In contrast, Japan has already demonstrated how such a conceptual framework can be transformed into practice. Nearly 25 years ago, the Japan Society for the Study of Obesity (JASSO) introduced the construct of “obesity disease” (Himan-sho in Japanese, where Himan means obesity and sho indicates disease/disorder), which closely parallels the concept of clinical  \nobesity proposed by the commission2. This diagnosis was designed to differentiate individuals requiring medical intervention from those with excess body weight but without immediate health consequences. The diagnosis requires BMI ≥25 kg/m2—reflecting the elevated metabolic risk of East Asian populations at relatively lower BMI thresholds—together with either3:  \n1.
