Nearly half of U.S. adults will have obesity by 2035, study warns

• According to research, nearly half (47%) of U.S. adults are projected to have obesity by 2035, a significant rise from 42% this year and a more than threefold increase since 1990.
• The rise is not uniform, with the highest prevalence forecast for Midwestern and Southern states and significant disparities across racial, ethnic and age groups, particularly affecting Black and Hispanic adults and younger females.
• Experts cite a multifaceted cause, including increased consumption of processed foods, more sedentary lifestyles (e.g., screen time), added stress and disrupted sleep patterns.
• Obesity is a major risk factor for serious conditions like type 2 diabetes, heart disease, cancer and arthritis, creating a substantial public health and economic burden.
• While GLP-1 drugs are a breakthrough, they are not a standalone cure. Reversing the trend requires broad systemic changes, such as improving access to affordable, healthy foods and addressing the underlying societal drivers of poor health.

A stark new projection warns that the obesity epidemic in the United States is set to intensify dramatically over the next decade, with nearly half of all adults expected to be living with the condition by 2035. Published in the Journal of the American Medical Association (JAMA), the original investigation forecasts that 126 million U.S. adults, almost 47% of the population, will have obesity a decade from now. This marks a significant climb from the estimated 107 million adults (42%) affected this year and a more than threefold increase from the 34 million adults (20%) with obesity in 1990.

The study, which analyzed data from more than 11 million U.S. adults, stands in contrast to recent self-reported surveys suggesting a slight decline and its authors urge policymakers to take note. “Given the association between obesity and adverse health outcomes and the resulting rapidly rising healthcare costs, these findings underscore the importance of addressing the burden of obesity in the U.S.,” the researchers wrote.

The projected rise is not uniform. The analysis indicates the highest prevalence will be in Midwestern and Southern states and significant disparities exist across racial, ethnic and age groups. Currently, 57% of non-Hispanic Black female adults have obesity, compared to nearly 50% of Hispanic females, 42% of Hispanic males and 40% of white males. The largest increases are projected for the youngest adult females, under age 35.

Experts point to a complex web of environmental and societal drivers fueling the trend. “The reasons are multifaceted,” said Kristin Kirkpatrick, RD, a dietitian at the Cleveland Clinic. “Our food has changed, which is a major factor. However, it’s not the only aspect of the story. Added stress, screen time (sedentary behavior), sleep patterns and concurrent increases in poor mental and physical health have all contributed.”

The path to reversal requires systemic change

Mir Ali, MD, a bariatric surgeon, echoed that complexity. “There is more of a sedentary lifestyle with people staying inside their homes and not being active,” he said. “There’s also been a great increase in the amount of processed foods. Foods that aren’t healthy have exploded in use.”

The health implications are severe. Obesity is a major risk factor for type 2 diabetes, heart disease, high blood pressure, cancer and arthritis. The study authors noted it is “associated with an increased risk of mortality and morbidity,” creating a substantial public health and economic burden.

While GLP-1 agonist drugs like Wegovy and Zepbound have revolutionized treatment, experts caution that they are not a standalone solution and face barriers of cost and access. “GLP-1s are also only one side of the story; being on one alone does not guarantee success,” Kirkpatrick emphasized. “Other lifestyle factors need to be adhered to.” As noted by BrightU.AI‘s Enoch, GLP-1 agonists are a class of medications that mimic a natural gut hormone to help lower blood sugar and promote weight loss. They are synthetic drugs inspired by peptides found in Gila monster venom, but are not themselves venom.

The path to reversal, specialists agree, requires systemic change focused on education and accessibility. “Better access to fresh, nutrient-dense foods may be the next logical next step,” Kirkpatrick said, stressing the need to make healthy choices affordable and convenient. David Cutler, MD, a family medicine physician, expressed a sobering outlook on the challenge ahead, citing the difficulty of sustained behavioral change.

“My guess is that obesity rates will continue to rise,” he said. “My basis for this conclusion is that human behavior is very difficult to change. Altering eating behaviors will be very challenging.”

The consensus is clear: without broad, concerted efforts to improve diets, increase physical activity and address underlying social drivers, the nation’s scale is set to tip further toward a costly health crisis.
