In slightly more than two decades, it is estimated that nearly 260 million individuals in the United States will be affected by overweight or obesity, as indicated by a recently published study.
This groundbreaking study, featured in the esteemed medical journal the Lancet, represents one of the first attempts to forecast the potential trajectory of the nation’s obesity crisis extending all the way to 2050. The findings predict that by this time, a staggering 43.1 million children and adolescents, along with 213 million adults, will fall into the categories of overweight or obese. In contrast, statistics from 2021 revealed that there were 36.5 million children and adolescents and 172 million adults facing similar challenges.
This alarming forecast indicates that hundreds of millions of Americans could soon contend with significant health complications related to a high body mass index (BMI), which range from diabetes, cancer, and cardiovascular issues, to various respiratory problems and mental health difficulties.
The study draws attention to the exorbitant health-related costs associated with obesity within the United States. In the year 2016 alone, healthcare expenses linked to obesity ranged between an unsettling $261 billion and $481 billion.
Individuals classified as overweight or obese — defined respectively as having a BMI exceeding 30 and one between 25 and 29.9 — are increasingly recognized as some of the most significant risk factors contributing to premature mortality and disability in the United States, studies highlight.
To formulate these advanced projections, researchers at the Institute for Health Metrics and Evaluation, based at the University of Washington, utilized a sophisticated model that analyzed historical data from a comprehensive 134 unique sources, which encompassed all major national surveillance surveys.
The study points out that the crisis of overweight and obesity has long been escalating within the American populace. Over the last 30 years, obesity rates among adults and older adolescents have doubled, with female adolescents aged 15 to 24 experiencing an even steeper increase in obesity prevalence compared to their male counterparts from 1990 to 2021.
“Obesity is at a crisis point throughout the USA,” stated Dr. Marie Ng, a co-author of the study and an associate professor with the Institute for Health Metrics and Evaluation, emphasizing the urgent need for action.
Of particular concern is the rising proportion of young people experiencing obesity. Research indicates that young individuals who are classified as overweight or obese face a significantly higher likelihood of struggling with weight issues later in life compared to their peers of average weight, highlighting a concerning trend for future populations.
The study also identified geographical disparities, noting that certain regions, particularly in the South, are disproportionately affected by obesity. States such as Oklahoma, Alabama, Arkansas, and Mississippi currently exhibit the highest prevalence of obesity and are expected to continue this trend, with notable increases projected for Colorado and New Mexico in comparison to 2021.
Alarmingly, statistics reveal that in Texas, more than half of all adolescent males between the ages of 15 to 24 are categorized as overweight or obese. In Mississippi, two-thirds of older adolescent females find themselves in the same troubling situation, while approximately 80% of adult women are similarly affected.
However, the researchers caution that their findings come with certain limitations. Future trends may diverge from historical patterns, and due to insufficient data, the researchers were unable to project obesity levels for children at the state level.
The current statistics regarding individuals suffering from overweight and obesity underscore a desperate need for stronger interventions at a population level to improve public health outcomes, according to the researchers.
“Our analysis lays bare the decades-long failure to tackle the growing overweight and obesity epidemic in the US,” expressed study co-author Emmanuela Gakidou, who co-founded the Institute for Health Metrics and Evaluation, highlighting the urgent call for comprehensive strategies.
The anticipated demand for medications aimed at treating obesity is projected to rise sharply; however, Ng cautions that these should not be viewed as “a silver bullet” solution. Many potential patients may find access to these treatments limited, and exorbitant costs could pose significant barriers.
Prevention strategies are vital, Ng emphasized, advocating for improved practices regarding pregnancy and infant feeding. Implementing healthier school meal programs, enforcing stricter regulations on junk food, and initiatives aimed at making fruits and vegetables more accessible to the public will be crucial. Additionally, creating safe, walkable neighborhoods is essential to encourage physical activity.
Evidence exists that solutions enacted at the population level can achieve notable success if a serious commitment to implementation is established, according to Dr. Barry Popkin, a distinguished professor in the Department of Nutrition at the University of North Carolina.
One of the contributors to obesity, Popkin noted, is sweetened beverages. In fact, more than 40 countries, as well as certain US cities like Philadelphia and Oakland, have instituted taxes on these beverages, leading to observable declines in overall calorie consumption among populations.
In Mexico, the implementation of a peso-per-liter excise tax on sugar-sweetened beverages yielded a marked 6% decrease in their purchase during the first year, as demonstrated by one of his studies. The following year saw an additional 4% reduction. Consequently, individuals began opting for water, which resulted in an overall reduction in calorie intake, as highlighted in his research.

Within just three years of introducing new food labeling in Chile, he noted, there was a significant 22% reduction in sodium consumption, followed by a noteworthy 33% decrease in sugar consumption and a similar 22% decline in overall calorie intake.
Popkin pointed out that a considerable challenge will be locating leadership within the United States willing to prioritize solutions to the obesity epidemic. He expressed skepticism about its elevation as a priority in a potential second Trump administration if his first term is any indication.
During his initial term, Trump’s proposed budgets consistently aimed to cut hundreds of billions of dollars from the Supplemental Nutrition and Assistance Program. Additionally, the Trump administration systematically rolled back numerous Obama-era regulations designed to improve children’s access to healthier school meals, and reinstated sugary beverages like chocolate milk into schools.
“Population solutions can be very effective,” concluded Popkin. “And clearly we need them, based on the rising statistics.”
How can multi-faceted approaches help address the obesity crisis in the U.S., particularly among adolescents?
Mplementing the beverage tax in Mexico, the country experienced notable shifts in public consumption habits. The results underscore the potential efficacy of policy-driven interventions aimed at reducing obesity rates.
the concerning trends in obesity within the U.S., particularly among adolescents and in specific geographic regions, call for immediate and sustained action. Addressing this public health crisis requires a multifaceted approach that incorporates healthier eating environments, better physical activity infrastructure, and strong community engagement, all while considering economic factors that influence access to healthier options.
