America’s long-standing battle against obesity may be showing its first significant signs of improvement in over a decade, with fewer states reporting extremely high rates. However, this fragile progress is immediately threatened by federal funding cuts to public health programs, raising concerns among experts about the nation’s ability to sustain momentum in preventing a chronic disease affecting 40% of its population.
For the first time in more than a decade, the United States has seen a decline in the number of states where adult obesity rates reach 35% or higher. This encouraging development, detailed in a new report released Thursday, offers a potential turning point in America’s persistent struggle with excess weight. Yet, this cautious optimism is tempered by significant concerns: recent federal cuts to staff and programs dedicated to addressing chronic diseases could critically endanger this nascent progress.
The Shifting Landscape of US Obesity: A Decade in Review
The latest analysis, conducted by the nonprofit group Trust for America’s Health (TFAH) based on U.S. Centers for Disease Control and Prevention (CDC) data, reveals that 19 states had obesity rates of 35% or higher in 2024. This marks a notable decrease from 23 states just one year prior. Despite this positive shift, the overall rate of obesity in the U.S. remains high, affecting approximately 40% of the population, a figure that has held steady according to a CDC report from last year. Dr. J. Nadine Gracia, president and chief executive for TFAH, emphasized the fragility of these findings, stating that “it’s too soon to call it a trend.”
Historically, the trajectory of obesity rates has been concerning. Before 2013, no U.S. state had an adult obesity prevalence at or above 35%. By 2019, a dozen states had reached this high threshold, and the number continued to climb steadily until this recent report. This persistent rise underscores the deep-rooted nature of the obesity epidemic, which is defined in adults as having a Body Mass Index (BMI) of 30 or higher. Obesity is a complex chronic disease linked to a host of serious health problems, including diabetes, stroke, cancer, and heart disease, making any progress against it particularly significant.
The Double-Edged Sword: Progress Amidst Funding Concerns
The encouraging data arrives at a precarious time for public health initiatives. Dr. Gracia warned that with “recent federal funding cuts, staff layoffs and eliminated programs,” this potential progress is “at risk.” This concern highlights a fundamental tension between acknowledging positive trends and ensuring the necessary infrastructure exists to foster long-term public health improvements.
The U.S. Health and Human Services Department (HHS) acknowledged the report, with spokesman Andrew Nixon stating the administration is “encouraged by the new data showing progress in the fight against obesity.” Nixon also indicated a strategic shift, explaining that HHS is “restructuring public health programs to eliminate waste, reduce bureaucracy, and redirect resources toward real prevention.” While the administration’s intent is to optimize resource allocation for prevention, public health advocates worry that these “restructuring” efforts could inadvertently dismantle effective programs and reduce capacity when sustained investment is most needed.
The report analyzed data from the CDC’s 2024 Behavioral Risk Factor Surveillance System (BRFSS), an annual telephone survey that meticulously collects data on health behaviors and chronic conditions across U.S. states and territories. This system is crucial for monitoring public health trends, and any reduction in federal support could impact the comprehensiveness and efficacy of future data collection and subsequent intervention planning.

State-by-State Snapshot
The 2024 BRFSS data provided a detailed breakdown of adult obesity rates across the nation:
- 19 states had obesity rates of 35% or higher.
- 22 states had rates between 30% and 35%.
- 9 states had obesity rates of below 30%.
These rates exhibited significant variation, ranging from a low of 25% in Colorado to a high of more than 40% in West Virginia. Interestingly, between 2023 and 2024, no state experienced statistically significant increases or decreases in its obesity rate, a marked change from the previous five years when 18 states saw significant increases. This stability, coupled with the overall drop in high-prevalence states, suggests a potential leveling off or even a slight reversal of the previous upward trend.
Unpacking the Potential Drivers of Change
The exact reasons behind the apparent improvements in obesity rates are not fully understood, but experts point to several potential factors. One significant contributor could be the wider adoption of new weight-loss drugs, such as Wegovy and Zepbound. These medications work by targeting appetite and slowing digestion, and their increased use might be beginning to influence reported health data. Aviva Musicus, a science director for the Center for Science in the Public Interest, an advocacy group, highlighted the potential impact of these pharmaceutical interventions.
Another suggested factor is the increased support for nutrition assistance programs during the COVID-19 pandemic. These programs may have played a crucial role in improving dietary access and quality for many individuals, leading to better health outcomes. Solveig Cunningham, an Emory University global health expert specializing in obesity, noted that the TFAH report also outlines a broad range of existing federal, state, and local efforts aimed at improving nutrition and boosting physical activity.
Cunningham, who was not involved with the research, observed that “the report would argue that some of these interventions may actually be successful.” This perspective suggests that comprehensive public health strategies, when adequately funded and implemented, have the potential to make a tangible difference in population-level health. The full report from Trust for America’s Health offers an in-depth look at these findings and their implications, and can typically be found on their official website, such as their State of Obesity report archives.
Looking Ahead: The Fight for Population-Level Prevention
The recent findings present both a challenge and an opportunity. While the slight decline in states with high obesity prevalence is a cause for cautious optimism, the overall high rate and the threat of federal funding cuts underscore the need for continued vigilance and investment in public health. The restructuring initiatives mentioned by the HHS, while framed as efficiency measures, must genuinely redirect resources towards “real prevention” rather than inadvertently weakening the public health infrastructure.
The concept of population-level prevention, championed by experts like Solveig Cunningham, is critical. It involves broad interventions that address the social, environmental, and economic determinants of health, aiming to prevent obesity before it develops. This approach contrasts with individual-level treatments, such as weight-loss drugs, though both have their place in a comprehensive strategy. Community discussions often revolve around the ethical considerations of reliance on pharmaceutical solutions versus the societal responsibility to create healthier environments through policy and public health programs. Sustained efforts in nutrition education, promotion of physical activity, and equitable access to healthy foods remain paramount.
The recent data serves as a powerful reminder that while progress is possible, it is neither guaranteed nor immune to policy decisions. The ongoing fight against obesity requires a delicate balance of individual responsibility, medical innovation, and robust public health investment from entities like the Department of Health and Human Services, ensuring that current gains are not eroded but built upon for a healthier future for all Americans.
