Every year, researchers crunch the data and map out where Americans are struggling most with weight – and the results aren’t random. The same states appear at the top of the list, year after year. Some of them are states you might expect. Others might surprise you. And when you look closely at the reasons why, the picture becomes a lot more complicated than “people just aren’t eating well.”
Obesity isn’t simply a personal failing. It’s a product of the environment people live in – the food available to them, the jobs in their area, the proximity of a grocery store versus a fast food chain, and how much money is left at the end of the month after rent is paid. Some states face a perfect collision of poverty, geography, and limited infrastructure that makes healthy living genuinely harder than it is elsewhere. Understanding those conditions isn’t about making excuses. It’s about understanding what’s actually driving the numbers.
Based on 2024 data from the CDC’s Behavioral Risk Factor Surveillance System, the states with the highest adult obesity rates were West Virginia at 41.4%, Mississippi at 40.4%, and Louisiana at 39.2%. Rounding out the top 10 are Alabama, Arkansas, Indiana, Kansas, Nebraska, Wisconsin, and Kentucky, with rates ranging between 37.2% and 38.9%. Here’s why each of them landed there.
1. West Virginia – 41.4%
West Virginia leads the entire nation with more than two in five adults living with obesity. That figure doesn’t exist in a vacuum – it connects directly to the state’s economic history. Coal counties in Appalachia suffer high rates of heart disease, obesity, smoking, diabetes, and opioid abuse, leaving them with some of the lowest life expectancies in the country. As the coal industry contracted and jobs disappeared, increased poverty led to increased obesity, since lower-income Americans often cannot afford healthy foods, and obesity, in turn, can trigger a cascade of other health conditions, including high blood pressure, diabetes, stroke, and heart disease.
Food access is a core problem. According to the Food Empowerment Project, food deserts can be described as “geographic areas where residents’ access to affordable, healthy food options is restricted or nonexistent due to the absence of grocery stores within convenient traveling distance.” The rural geography of West Virginia amplifies these food deserts across the mountain state, reducing the opportunity for many residents to make healthier food choices. Systemic barriers – including food insecurity, low household income, high poverty rates, housing instability, and lack of access to healthcare – all compound the problem, and West Virginia consistently runs above the national average on adult and child poverty.
West Virginia not only has the highest obesity rate in the U.S., it also leads in type 2 diabetes rates at 15.7%. For residents trying to change their health outcomes, the structural barriers are enormous. The practical step for anyone in a food desert, anywhere in the country, is to understand that calorie-dense processed food isn’t a personal choice so much as a survival strategy – and policy change is what closes that gap.
2. Mississippi – 40.4%
Mississippi ranks second nationally and has long been near or at the very top of this list. Mississippi has the highest rate of food insecurity in America. Food insecurity means people struggle to consistently access enough food to maintain a healthy diet, and research shows it’s a risk factor for obesity – people often rely on lower-cost, calorie-dense foods that are less nutritious.
Studies aimed at identifying environmental, societal, and structural influences on high obesity rates in Mississippi Delta communities found that approximately two out of five respondents lived in areas designated as food deserts by the USDA’s Food Access Research Atlas. Researchers identified multiple contributing factors including lack of health insurance, poverty, rurality, shortages of primary care providers, poor infrastructure, and older age.
Mississippi’s obesity problem is also tied to a food culture centered around meals high in calories, fat, and sugar, alongside significant challenges with food deserts where healthy options are scarce. The combination of culture, poverty, and infrastructure is difficult to separate. Anyone living in this environment faces real obstacles – and the most actionable thing local and federal programs can do is increase access to primary care providers and bring affordable grocery options closer to rural communities.
3. Louisiana – 39.2%
Louisiana ranks third, and its story shares many of the same threads as its neighbors. State health statistics show Louisiana has elevated rates of type 2 diabetes and cardiovascular disease, and county-level data reveal higher obesity prevalence in rural parishes where residents face longer travel distances to primary care and limited access to full-service grocery stores.
Food insecurity is also high in Louisiana, affecting 683,000 residents across the state. Louisiana’s struggle with obesity is compounded by its rich, calorie-heavy regional cuisine – one of the most celebrated food cultures in the country, but one that historically centers dishes high in fat, salt, and refined carbohydrates. Cultural food traditions are deeply personal, and any effective public health intervention has to work with them, not against them.
Louisiana ranks in the top five for the highest obesity rate, food insecurity rate, and diabetes rate, and is also among the top states for the worst air quality. That last point matters: poor air quality limits outdoor activity, and low physical activity levels are consistently linked to higher obesity. Organizations like the Louisiana Chronic Disease Collective have focused on improving healthcare access and policy, but progress is slow when the underlying poverty and food infrastructure problems remain unaddressed.
4. Alabama – 38.9%
Alabama ties for fourth place in the nation. The state reports adult diabetes prevalence above 15%, one of the highest rates nationally, tracking closely with its obesity patterns. Roughly 38.9% of Alabama adults were living with obesity, and like many of the other high-ranked states, Alabama has a high prevalence of food deserts with limited access to fresh fruits, vegetables, and other nutritious foods.
Food scarcity is a serious issue in Alabama, affecting about 23% of children and 17% of adults in the state. Healthcare access is another consistent barrier. Alabama faces major health challenges including high rates of obesity, diabetes, and hypertension, and its healthcare system struggles with accessibility, particularly for rural residents, while overall levels of physical activity remain low.
The state’s Black Belt region – a stretch of counties named for their dark fertile soil but marked today by concentrated poverty – shows particularly concentrated health disparities. Without access to a full-service grocery store, a nearby clinic, or a safe place to walk or exercise, individual behavior change is genuinely limited in what it can achieve. Expanding Medicaid coverage and food access programs would likely move the needle more than any single lifestyle campaign.
5. Arkansas – 38.9%
Arkansas ties Alabama at 38.9% and has consistently ranked among the hardest-hit states in the country. The state reports hypertension rates above 40% and diabetes prevalence near 14%, and the USDA’s Food Access Research Atlas, a mapping tool that allows users to investigate multiple indicators of food store access, shows large portions of eastern and southern Arkansas – particularly in Delta counties – designated as low-access food areas.
High poverty levels restrict access to healthy food and opportunities for physical activity, and with fewer venues for exercise, many residents rely on cheap, calorie-dense options that significantly contribute to the state’s high obesity rate. Nearly 19% of people in Arkansas have trouble accessing healthy food.
There are efforts underway. In 2022, the Arkansas Governor’s Food Desert Working Group began a program to work toward eliminating food deserts, developing a plan that includes tax incentives to encourage grocers to open stores in underserved areas. Whether those incentives prove enough to move the needle will depend on sustained funding and follow-through. For residents living in affected counties right now, programs like WIC and SNAP remain critical lifelines.
6. Indiana – 38.4%
Indiana might not be the first state people think of when discussing obesity, but roughly 38.4% of adults in Indiana have obesity, giving the state the sixth-highest prevalence in the nation. Indiana sits squarely in the Midwest, a region with a long history of high obesity rates driven by its industrial economy, car-dependent communities, and lack of walkable infrastructure in many areas.
In 2024, at least 1 in 4 adults in all U.S. states and territories had obesity. Indiana reflects the Midwest’s pattern closely. Many of its communities were built around manufacturing and are structured in ways that make driving everywhere unavoidable, walking and cycling uncommon, and access to fresh food dependent on owning a car. When manufacturing jobs disappear, as they have in many Indiana towns, the economic insecurity left behind further raises obesity risk.
Obesity levels are typically lower among people with college degrees and for people with higher household incomes, suggesting that the affordability of healthy foods plays a significant role in national obesity rates. Indiana’s urban-rural divide – with higher obesity in its rural counties – mirrors this pattern. Access to nutrition education, community health programs, and walkable neighborhoods can make a concrete difference in these communities.
7. Kansas – 37.6%
Kansas records a 37.6% adult obesity rate. County-level CDC maps show higher obesity rates in central and western Kansas, where populations are more rural, and USDA food-access data indicate many of these counties have limited proximity to full-service grocery stores.
Adults living in rural areas have had higher obesity rates than their urban counterparts since 2016, a trend that continued through 2024 even as urban obesity rates declined. Kansas, with its wide open plains and scattered rural population, exemplifies this dynamic. Driving 30 or 40 miles to reach a grocery store isn’t hypothetical for some Kansas residents – it’s a weekly reality. When the alternative is a gas station or a dollar store, processed food becomes the default.
Kansas also reflects the broader national pattern around sedentary behavior. Physical-activity surveillance shows Kansas adults are less likely than the national average to meet aerobic exercise guidelines, reinforcing the link between geography, access, and obesity outcomes statewide. Building trails, investing in community recreation facilities, and supporting local food cooperatives are among the practical interventions that have shown results in comparable rural markets.
8. Nebraska – 37.6%
Nebraska ties Kansas with a 37.6% adult obesity rate. State health data show adult hypertension affects roughly one in three Nebraskans and diabetes prevalence exceeds 10%, both conditions strongly associated with obesity. County-level CDC maps identify higher obesity rates in central and western Nebraska, where populations are more rural.
The USDA’s Food Access Research Atlas data shows the rural obesity rate rose from 47.8% to 48.3% between 2022 – 2023 and 2023 – 2024 – a reminder that rural America, which dominates the geography of states like Nebraska, is moving in the wrong direction even as some urban areas show modest improvement.
Nebraska has strong agricultural roots but also faces the irony common to many farming states: growing food doesn’t automatically mean having access to nutritious, affordable food locally. Small towns that once had independent grocery stores have watched them close as large chains concentrate in bigger cities. Farmers’ markets and local food hubs are part of the solution, but they need sustained investment and community buy-in to reach the populations that need them most.
9. Wisconsin – 37.4%
In Wisconsin, 37.4% of adults have obesity, ranking the state ninth nationwide. Wisconsin doesn’t fit the stereotypical profile of a high-obesity state – it’s not in the Deep South, it’s not Appalachia, and it has reasonably strong public health infrastructure. But the same structural forces at play elsewhere are present here too, particularly in its rural northern counties.
People living in rural communities tend to have higher rates of obesity compared to people living in metro areas, and Wisconsin’s geography is predominantly rural outside of Milwaukee and Madison. Long winters limit outdoor activity for months at a time, fast food is often more accessible than fresh produce in smaller communities, and lower-income residents face the same calorie-for-dollar math that drives poor dietary choices elsewhere.
Wisconsin also reflects the national link between obesity and processed food consumption. There is mounting evidence connecting ultra-processed foods with obesity and other negative health effects, and Wisconsin’s food environment in rural areas – dominated by convenience stores and fast food chains – makes processed food the path of least resistance for many families.
10. Kentucky – 37.2%
Kentucky rounds out the top 10 with a 37.2% adult obesity rate. High poverty rates in Kentucky limit access not only to healthy food but also to education about healthy eating habits. Traditional regional meals are often fried and calorie-dense, and the distribution of rural areas makes it harder for residents to access spaces for physical activity.
Kentucky struggles with a high prevalence of smoking, high blood pressure, and obesity, and these lifestyle factors contribute to a variety of chronic diseases including heart disease, cancer, and respiratory problems. The intersection of smoking and obesity is particularly damaging – both individually and together, they dramatically shorten life expectancy and strain an already underfunded rural healthcare system.
Kentucky’s poor air quality and high rate of adult smokers contribute to its position among the most unhealthy states. Appalachian Kentucky faces many of the same economic pressures as neighboring West Virginia – declining traditional industries, concentrated rural poverty, and limited healthcare access. Expanding telehealth services and community health worker programs has shown promise in reaching isolated residents who can’t easily travel to a clinic.

What This Means for You
Obesity is tied not just to individual behavior but to systemic factors: access to healthy foods, safe places to exercise, health education, socioeconomic status, and broader social determinants of health. The states topping this list share a consistent set of conditions – concentrated poverty, rural geography, limited food access, and underfunded healthcare infrastructure. Knowing that context doesn’t make the health risks less real, but it does make clear that telling people to “eat less and move more” is an incomplete answer.
In 2024, 19 states had adult obesity rates at or above 35%, down from 23 states the prior year, according to an analysis of the latest CDC data by the nonprofit Trust for America’s Health. That’s the first decrease in the number of states at that level since the dataset began in 2011, and it matters. But as the group’s president cautioned, “it’s too soon to call it a trend” – and with recent federal funding cuts, staff layoffs, and eliminated programs, “this potential progress is also at risk.” If you live in one of these states, the most effective things you can do – beyond making individual dietary choices – are to support local food access initiatives, advocate for expanded Medicaid coverage, and push for investment in walkable community infrastructure. Obesity is a community-level problem, and solving it requires community-level action.
