A global report from medical experts emphasizes the need for a more nuanced definition of obesity, urging doctors to assess overall health rather than relying solely on BMI. The report distinguishes between "clinical obesity" for those with health issues and "pre-clinical obesity" for healthier individuals, promoting personalized care and intervention strategies.

Redefining Obesity: A Global Call for Nuanced Health Perspectives
Experts advocate for a new understanding of obesity, proposing a distinction between clinical and pre-clinical obesity for improved healthcare outcomes.
A groundbreaking report published in The Lancet Diabetes & Endocrinology highlights the urgent need to redefine obesity, advocating for a more nuanced understanding that considers overall health beyond the body mass index (BMI). Led by Prof Francesco Rubino from King's College London, the expert panel consisting of over 50 medical professionals challenges the conventional approach, suggesting that a rigid BMI classification may lead to an overdiagnosis of obesity among otherwise healthy individuals.
The report posits that obesity should be viewed as a spectrum. While some individuals live active lives despite excess body fat, others experience significant health issues related to their weight. Those suffering from chronic illnesses resulting from obesity should be classified as having "clinical obesity," while healthy individuals at risk should be identified as experiencing "pre-clinical obesity."
Currently, obesity is defined by a BMI over 30, a measurement that does not account for variations in fat distribution, muscle mass, or the relative health risks associated with obesity-related health conditions. The report calls on healthcare systems to adopt a new diagnostic model that looks beyond BMI to include factors such as waist-to-height ratios and a thorough medical history that evaluates the impact of obesity on daily life and organ health.
This redefining aims not only to facilitate more accurate diagnoses but also to tailor treatment approaches—offering weight-loss support and counseling for those diagnosed with pre-clinical obesity, and more intensive interventions for those with clinical obesity, potentially including medication. Experts emphasize that distinguishing between these categories can improve treatment outcomes and alleviate the pressure on healthcare resources.
Children's obesity expert, Prof Louise Baur, asserts that this new classification will lead to more appropriate care for individuals across all ages, reducing instances of unnecessary treatment for those who may not require immediate intervention. Despite concerns around budget constraints that may impact resource allocation towards pre-clinically obese patients, the Royal College of Physicians supports the report as essential for allocating care to those most in need while ensuring early intervention for emerging health risks.
As the therapy landscape shifts with the rise of effective weight-loss medications now becoming available, this redefinition of obesity may fundamentally influence how healthcare providers approach weight management and treatment strategies in the future.
