Conventional frameworks emphasize reproductive and androgenic features, while relying heavily on body mass index (BMI) as a proxy for adiposity. However, BMI fails to capture visceral fat distribution, which is a stronger determinant of insulin resistance, low-grade inflammation, and cardiovascular risk. Emerging evidence highlights waist-to-height ratio (WHtR) and waist circumference (WC) as superior markers of central adiposity and metabolic dysfunction in PCOS. Based on pooled data from recent studies, consolidated cut-offs for PCOS and insulin-resistant PCOS (PCOS-IR) were derived, allowing phenotype-based stratification according to adiposity patterns. These evidence-based thresholds distinguish the metabolic transition from general to insulin-resistant PCOS, providing practical reference points for clinical use. Based on these insights, we propose a hypothesis-based stratification of PCOS into three adiposity-driven phenotypes: lean PCOS with central adiposity, obese PCOS with predominant central adiposity, and obese PCOS with peripheral adiposity. This stratification framework integrates general and central adiposity measures to identify women at varying metabolic risk levels more accurately. Moving beyond BMI towards adiposity-driven classification is therefore a crucial step toward diagnostic precision in reproductive endocrinology.</div></div>","PeriodicalId":37876,"journal":{"name":"Obesity Medicine","volume":"58 ","pages":"Article 100664"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145519805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some individuals remain metabolically healthy (MHO), while others progress to metabolically unhealthy obesity (MUO), facing severe risks like diabetes and heart disease. This critical review assesses the genetic underpinnings of this crucial distinction, focusing on the leptin receptor (LEPR), a key component in the regulation of our body's energy balance. Leptin, a hormone from fat cells, signals satiety through the LEPR. When genetic variations (polymorphisms) in LEPR disrupt this delicate signalling, it can lead to leptin resistance, a state contributing to weight gain and metabolic dysfunction. This review critically evaluates the evidence for how specific LEPR polymorphisms may influence the phenotypic divergence between MHO and MUO, highlighting the complex and population-specific nature of these associations. While variants like Q223R show inconsistent associations, others, such as K656N (rs8179183) and rs3790435, appear to directly contribute to the MUO phenotype by affecting fat distribution and inflammatory pathways. Understanding these genetic influences is paramount, as it shifts our view of obesity from a monolithic condition to a spectrum, revealing how individual genetic predispositions can dictate metabolic resilience or vulnerability. This work is crucial for developing more precise risk assessments and personalized interventions, ultimately paving the way for more effective strategies to promote metabolic health and mitigate the diverse impacts of obesity.</div></div>","PeriodicalId":37876,"journal":{"name":"Obesity Medicine","volume":"58 ","pages":"Article 100660"},"PeriodicalIF":0.0,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145417219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This comprehensive narrative review synthesises current evidence on AI applications in obesity management, examining technological innovations from predictive risk models to personalised digital therapeutics. The review explores AI-based diagnostic tools utilising computer vision for body composition analysis, predictive algorithms identifying high-risk individuals using electronic health records, personalised behavioural interventions powered by reinforcement learning, and remote monitoring systems integrating wearable technologies with intelligent data analytics. Furthermore, it investigates clinical effectiveness of AI-driven digital therapeutics platforms and examines AI integration within clinical decision support systems. The analysis reveals significant benefits including enhanced scalability for population-level interventions, improved personalisation through real-time data integration, increased precision in risk stratification, and potential cost-effectiveness through optimised resource allocation. However, substantial challenges remain, including data privacy and security concerns, algorithmic bias that may exacerbate health disparities, limited large-scale clinical validation, declining user engagement over time, and complex regulatory and ethical considerations.
