Abstract

Abstract
Background: The 2013 obesity guideline focused largely on weight as a numeric target. Emerging evidence and the 2026 Cardiovascular–Kidney–Metabolic (CKM) Guideline have shifted the paradigm, positioning excess adiposity—particularly abdominal/visceral fat—as a causal driver of multi‑organ disease.

Objective: To summarise reasons for retiring the 2013 document and to outline the CKM Guideline’s integrated, organ‑protective approach to assessing and treating adiposity within CKM syndrome.

Methods: We review epidemiologic associations linking incremental increases in BMI and central adiposity to heart failure, coronary events, stroke, and kidney disease, and summarise guideline recommendations to combine BMI with waist circumference, reframe weight as a driver rather than an endpoint, offer lifestyle interventions with adjunctive obesity pharmacotherapy, and refer selected patients for metabolic/bariatric surgery. We also describe guidance on non‑stigmatizing communication strategies.

Results/Conclusions: The 2026 CKM Guideline replaces the 2013 weight‑centric approach because treating adiposity as a modifiable driver better aligns prevention and treatment with downstream cardiovascular and renal benefits. Routine measurement of waist circumference, earlier use of effective pharmacotherapies, and appropriate surgical referral create opportunities to reduce CKM incidence and progression. The guideline’s patient‑centred messaging aims to reduce stigma and improve engagement, supporting broader implementation of multisystem treatments that deliver benefits beyond weight loss

Why the 2013 Obesity Guideline Was Retired A paradigm shift from weight-as-number to weight-as-driver in a multi-organ syndrome Figure 5. Why the 2013 Obesity Guideline Was Retired — mechanism overview (illustrative; labels added for education). The 2026 CKM guideline formally replaces the 2013 guideline for managing overweight and obesity, reframing body weight within an interconnected multi-organ syndrome rather than as a standalone condition.1 The shift is conceptual as much as clinical: excess weight—especially abdominal adiposity—is identified as a key driver of CKM development and progression, not merely a cosmetic or metabolic endpoint.1 The quantitative case is compelling. Each 5-unit increase in BMI is associated with a 41% higher risk of heart failure, and excess weight raises heart disease and stroke risk by at least 21% in men and 32% in women.1 These effect sizes justify treating adiposity as a modifiable driver of cardiovascular and kidney outcomes. The epidemiology underscores the urgency: 40% of U.S. adults and 21% of children and adolescents have obesity, and more than 70% of the population is affected by obesity or overweight.3,4 While these figures are American, the trajectory in urban India mirrors the trend, making the reframing globally relevant. Guideline chair Chiadi E. Ndumele captured the philosophy: “Weight is not just about a number on a scale—people with the same body weight can have very different health profiles.”1 The guideline accordingly shifts the paradigm toward proactive prevention rather than reactive care, integrating waist circumference alongside BMI and pairing lifestyle change with pharmacotherapy and, where appropriate, metabolic surgery. The reframing has direct therapeutic consequences. By treating adiposity as a modifiable driver rather than a fixed trait, the guideline pairs lifestyle change with obesity pharmacotherapy and, where indicated, metabolic and bariatric surgery, and it emphasises abdominal adiposity—measured with waist circumference—alongside BMI.2 This matters because two people at the same weight can carry very different visceral-fat and cardiometabolic risk, a distinction the 2013 weight-centric document could not capture.1 Recognising that weight conversations can be stigmatising, the guideline also provides non-judgmental scripting to open the discussion—for example, “Is now a good time for us to address your weight and your health and how they may be affecting each other?”1 This attention to communication reflects a broader move toward patient-centred, respectful care. The retirement of the 2013 document therefore represents more than an update: it is a redefinition of obesity as a treatable driver of systemic disease, with growing evidence that modern obesity medications confer multisystem benefit beyond weight loss alone.6 References 1.
