75% Percent of US Adults Can Be Considered Obese
A revised medical framework for defining obesity could dramatically expand the number of American adults considered obese, according to new research that looks beyond body mass index alone and incorporates additional physical measurements and health indicators.
Using national health data collected between 2017 and 2023, researchers analyzed information from more than 14,000 people, representing roughly 237.7 million U.S. adults. When the broader criteria were applied, an estimated 75.2% of adults met the threshold for obesity. Under the traditional BMI-only approach, that figure stood at about 40%.
The analysis, published in JAMA Network Open, was conducted by investigators affiliated with Harvard University, Yale New Haven Health, and Beth Israel Deaconess Medical Center, and was reported by ABC News.
The work was prompted by recommendations from the The Lancet Diabetes & Endocrinology Commission, a collaboration between the medical journal and King’s Health Partners Diabetes, Endocrinology and Obesity. That commission proposed redefining obesity to include measurements such as waist circumference, waist-to-hip ratio, and waist-to-height ratio, in addition to BMI.
Although the updated definition has been endorsed by more than 70 medical organizations worldwide, the study’s authors noted that its real-world impact had not previously been assessed.
“BMI is the standard measure for determining criteria for obesity. It’s the most widely known metric,” said Dr. Erica Spatz, a cardiologist at Yale School of Medicine and a co-author of the study.
Spatz explained that BMI on its own fails to capture the role of adipose tissue. While this type of tissue is less visible, it plays a central role in insulating organs, storing energy, and producing hormones that regulate appetite, and “is more associated with high blood pressure, diabetes, and heart disease.”
To reach their conclusions, the researchers relied on data from the National Health and Nutrition Examination Survey, a nationwide program run by the Centers for Disease Control and Prevention that tracks the health of both children and adults across the country.
Dr. Fatima Cody Stanford, an associate professor of medicine and pediatrics at Massachusetts General Hospital and Harvard Medical School, said the findings underscore the scale of the problem, even though she was not involved in the research.
“We do have a major problem,” Stanford said. “Obesity is by far the most significant chronic disease in human history … we need to be doing a better job of treating it, make sure that we have the clinicians that are trained to identify not only obesity itself, but the over 230 chronic diseases associated with it, and making sure that we have a healthier society.”
