Consensus Statement on Obesity

In 2022, the leading US organizations with a primary focus on obesity came together with the intention of addressing the various roadblocks that they each faced in addressing efforts to improve access to obesity treatment and the reduction of the stigma and bias surrounding this disease. The organizations were: The Obesity Society, the Obesity Action Coalition, the Obesity Medicine Association, the American Society for Metabolic and Bariatric Surgery, the Stop Obesity Alliance, and the Academy of Nutrition and Dietetics. As part of our discussion, we agreed that it would be beneficial to come to a consensus on the definition of obesity. Our discussions led us to develop the consensus statement below to give us a shared starting point for how we talk about obesity, and which is consistent with how we discuss other chronic diseases. As the core organizations that address obesity, we worked together to write this statement and have agreed to use it as the central tenet in our communications around obesity.

Consensus Statement

Obesity is a highly prevalent chronic disease characterized by excessive fat accumulation or distribution that presents a risk to health and requires lifelong care. Virtually every system in the body is affected by obesity. Major chronic diseases associated with obesity include diabetes, heart disease, and cancer.

The body mass index (weight in kg/height in meters2) is used to screen for obesity, but it does not displace clinical judgement. BMI is not a measure of body fat. Social determinants, race, ethnicity, and age may modify the risk associated with a given BMI.

Bias and stigmatization directed at people with obesity contributes to poor health and impairs treatment.

Every person with obesity should have access to evidence-based treatment.

Country’s Leading Obesity Care Organizations Develop Consensus Statement on Obesity

Six U.S. organizations dedicated to the prevention and treatment of obesity collaborated to develop a consensus statement on obesity, a complex, chronic disease that impacts nearly 42% of adults and 19% of children and adolescents. This unified effort aims to address the various roadblocks that the organizations face when addressing efforts to improve access to obesity treatment and reduce weight stigma and bias surrounding the disease.

Study: 40-year follow up shows significant reduction in death rates after bariatric surgery

A new retrospective study with up to 40 years of follow up shows significant reductions in death rates from all causes and cause-specific conditions such as cardiovascular disease, diabetes and cancer in patients who have undergone bariatric surgery compared to non-surgical participants with severe obesity, according to a new study in Obesity, The Obesity Society’s (TOS) flagship journal.

Novel workplace lifestyle intervention leads to meaningful weight-loss, maintenance

Despite lifestyle interventions for weight-loss having limited effectiveness in workplaces when evaluated in randomized trials, a new program named Healthy Weight for Living (HWL) implemented with and without meal replacements and delivered in person or by videoconference reveals a significant weight loss in employees after six months, according to a new study in Obesity, The Obesity Society’s (TOS) flagship journal.

Obesity-focused Organizations Issue Statement in Support of New AAP Clinical Guideline on Childhood Obesity

On Jan. 9, 2023, AAP published its first clinical practice guideline on the treatment of childhood obesity, replacing recommendations last made in 2007. The new recommendations emphasize the need for an intensive and comprehensive approach that includes assessing risk factors, evaluating for comorbidities and offering treatment options using shared decision making with the child and family.
