Introduction: Obesity has historically been diagnosed using the Body Mass Index (BMI), a simplified tool for a complex disease that does not consider individual metabolic, cardiovascular, functional, or mental health variations. The Lancet Commission’s new obesity classification, was informed by 60 world experts including three Irish experts, Professor Edward Gregg, Professor Carel le Roux, and Vicky Mooney. The Irish Society for Clinical Nutrition and Metabolism (IrSPEN) also endorsed the findings which redefines obesity into Pre-Clinical Obesity and Clinical Obesity. This distinction aims to improve precision in diagnosis and management by shifting the focus from individual weight on the scale to overall health status.
