The Brazilian Association for the Study of Obesity (ABESO) and the Brazilian Society of Endocrinology and Metabolism (SBEM) have recently proposed a new classification of obesity based on the maximum weight attained in an individual’s lifetime, as an additional tool to enhance understanding of the disease and facilitate discussions about treatment. In this classification, people with obesity (PwO) who lose a certain percentage of their weight are categorized as having "reduced" or "controlled" obesity. While the classification aims to improve patient care, there is limited data on PwO perceptions. To explore this, a cross-sectional online survey was conducted with 500 PwO, including an explanation and clinical case illustrating the new classification. The survey revealed that 94% of participants were certain or almost certain of their maximum weight, however 64% of them had never been asked about it by a healthcare professional (HCP). 65% of PwO believe that reaching a normal body mass index is necessary for improving their health and quality of life, despite evidence indicating that modest weight loss can enhance health outcomes. After reading about the new classification, 82% found it useful for changing perceptions about obesity treatment; 66% felt it would encourage them to seek treatment; 63% believed it would help with treatment maintenance; and 74% indicated they would feel better achieving "controlled obesity," even if the weight loss fell short of their goals. The majority agreed that the classification could help establish realistic goals (77%), reduce biases from HCPs towards PwO (68%) and make HCPs less strict with patients about weight loss (64%). For 74% of PwO, HCPs should adopt the new classification in treating obesity. Overall, PwO perceived the classification as beneficial for encouraging treatment and reducing stigma.
