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.

Obesity CALL FOR PAPERS

“Long Covid” and Obesity (Impact Factor: 9.298)

Submit Your Manuscript Today!

Over the past two years, Obesity has provided rapid online publication of manuscripts on obesity-related aspects of the COVID-19 epidemic. Emerging information indicates that after a SARS-CoV-2 diagnosis, 20% of individuals may develop persistent, unresolving symptoms that can last four weeks or longer, now termed post-acute sequelae of SARS-CoV-2 (PASC), and large-scale observational data suggests increasing BMI may be a risk factor.

As the official journal of The Obesity Society and the premier source of information for obesity research and discovery, Obesity seeks submission of scientific data on the following topics:

  • Potential mechanistic drivers of “long COVID” in individuals with obesity, including immune impairment and of latent viruses
  • Effect of obesity and related psychological stressors on the resolution of symptoms and recovery rate across PASC phenotypes
  • Response to therapy, based on obesity status, in patients recovering from PASC
  • Other possible contributors to PASC that may be of interest to readers of Obesity including development of auto anti-bodies, residual viral load of SARS-CoV-2 including in adipose tissue, damage to lungs and other organs, small fiber neuropathy, and microscopic blood clots

Accepted submissions will have rapid online publication ahead of print.

Please submit your manuscript at https://mc.manuscriptcentral.com/obesity, and be sure to read the latest COVID-19 research on our journal website.
