For the first time in more than a decade, the number of U.S. states reporting adult obesity rates at or above 35 percent has dropped, signaling a potential shift in the nation’s long-standing struggle with excess weight. According to an analysis by the nonprofit Trust for America’s Health (TFAH) of the latest data from the Centers for Disease Control and Prevention (CDC), 19 states recorded obesity rates of 35 percent or higher in 2024. This represents a decrease from the 23 states that met this threshold in the previous year. This marks the first reduction in states at or above the 35% obesity level since this specific data collection began in 2011.
Historic Shift in State Obesity Rates
The findings from the “State of Obesity 2024: Better Policies for a Healthier America” report highlight a significant milestone. Historically, adult obesity rates have shown a persistent upward trend across the country. In 2012, prior to this current dataset’s tracking period, no state had an adult obesity rate at or above 35 percent. The decrease observed between 2023 and 2024 is particularly noteworthy, as it follows a period where obesity rates had been steadily climbing. Between 2018 and 2023, 28 states experienced statistically significant increases in adult obesity rates. The report indicates that while progress is being made in some areas, the overall national obesity rate remains alarmingly high.
The National Obesity Landscape
Nationally, the prevalence of obesity among American adults continues to be a significant public health challenge, with approximately 40 percent of the U.S. population affected. Recent data from the National Health and Nutrition Examination Survey (NHANES) for 2021-2023 indicates that about 40.3 percent of adults had obesity, suggesting a potential stabilization in the overall national rate, though it remains substantially higher than in previous decades. Some research using insurance claims data even suggests a slight decrease in the national obesity prevalence for the first time in over a decade by 2023.
Persistent Disparities and Geographic Patterns
Despite the encouraging news at the state level, obesity remains unevenly distributed across the american population. The highest rates of obesity in 2024 were seen in states like West Virginia (41.4%), Mississippi (40.4%), and Louisiana (39.2%). Conversely, states with the lowest adult obesity rates in 2024 included Colorado (25.0%), Hawaii (27.0%), and Massachusetts (27.0%).
Significant disparities persist along racial and ethnic lines, with Black and Latino adults reporting the highest obesity rates. Furthermore, individuals living in rural communities tend to experience higher obesity rates compared to those in urban areas. Obesity rates also continue to rise among children and adolescents, with nearly 20 percent of U.S. youth aged 2 to 19 now having obesity.
Complex Factors Driving Obesity
The causes of obesity are multifaceted, stemming from a complex interplay of genetics, individual behaviors, and broader societal and environmental factors. Socioeconomic status, poverty, limited access to affordable, healthy foods (food deserts), lack of safe spaces for physical activity, sedentary lifestyles, and industry marketing practices all contribute to the national health crisis.
Progress at Risk from Funding Cuts
While the reduction in states with high obesity rates is a positive development, public health experts caution that this progress is fragile and at risk. Concerns have been raised regarding recent federal actions, including funding cuts, staff layoffs, and the elimination of chronic disease prevention programs. Dr. J. Nadine Gracia, president and CEO of TFAH, stated that it is “too soon to call it a trend” and that potential progress is endangered by these reductions. A spokesperson for the U.S. Health and Human Services Department acknowledged the encouraging data and indicated that public health programs are being restructured to improve efficiency and focus on prevention. However, proposed budget cuts for critical CDC centers, such as the National Center for Chronic Disease Prevention and Health Promotion, raise concerns about the sustainability of public health initiatives.
A Cautiously Optimistic Outlook
The news news of fewer states exceeding the 35% obesity threshold offers a glimmer of hope in the ongoing fight against obesity. However, the persistent high national rates, significant demographic disparities, and the precarious state of public health funding underscore the need for continued, robust investment in prevention strategies and health equity. Sustained policy action and community-level interventions will be crucial to solidify this progress and address the complex, systemic issues underlying the obesity epidemic in America.
