Honestly, if you look at the headlines from five years ago, you'd think we were on a one-way flight to a health collapse. But things are looking... different lately. Kinda weird, actually. For the first time in what feels like forever, the percentage of obese people in USA hasn't just stopped climbing—it’s actually dipped.
According to the latest Gallup data for 2025, the adult obesity rate in the U.S. has eased down to 37.0%.
That might not sound like a revolution when you realize that in 2022, we hit a record high of 39.9%. But think about that for a second. We’re talking about roughly 7.6 million fewer people classified as obese than just three years ago. It’s the first statistically meaningful decline we've seen since George W. Bush was in office.
Why the Needle is Finally Moving
So, what changed? Did we all suddenly develop an obsession with kale and 5 AM marathons?
Not exactly.
While public health experts at the Trust for America’s Health (TFAH) have been pushing for better nutrition policies for decades, the real "disruptor" is sitting in a pharmacy fridge. It's the GLP-1 receptor agonists. You know them as Ozempic, Wegovy, and Zepbound.
Basically, the surge in these medications has mirrored the drop in obesity rates almost perfectly. Since early 2024, the number of Americans using these injections for weight loss has more than doubled.

Check this out:
- 12.4% of all U.S. adults are now using a GLP-1 drug.
- The biggest "winners" (if you want to call them that) are people in the 50–64 age bracket. Their obesity rates dropped by 5 full percentage points recently.
- Women are seeing a faster decline than men, likely because they’re using these medications at higher rates (about 15.2% vs 9.7%).
It's a massive shift. But don't let the optimism blind you.
While the "headline" number is down, the percentage of people with severe obesity (a BMI of 40 or higher) actually ticked up to 9.7% in the most recent NHANES data. That is a heavy number. It suggests that while the "average" case of obesity is being managed better by new drugs, the most extreme cases are still proving incredibly hard to budge.
The State-by-State Reality
The "United" States isn't very united when it comes to the scale. Where you live basically determines your risk profile.
If you're in Colorado, you’re looking at the lowest obesity rate in the nation at 25.0%. On the flip side, West Virginia is still struggling immensely, with a rate of 41.4%. Mississippi and Louisiana aren't far behind.
The 35% Threshold
There’s this benchmark that health wonks obsess over: states where more than 35% of the population is obese.

In 2023, there were 23 states in that "red zone."
By late 2024, that number dropped to 19.
It’s the first time we’ve seen states fall out of that category since the CDC started tracking this specific dataset in 2011. It’s a win. A small one, sure, but after fifteen years of losing, you take what you can get.
What it’s Costing Us (Literally)
We can talk about "health" all day, but the dollars tell a much grimmer story.
Obesity isn't just a physical state; it's a massive economic weight. Direct medical spending on obesity and its complications—think Type 2 diabetes, hypertension, and heart disease—is north of $261 billion annually.
A person living with Class III obesity (severe) ends up with medical bills that are, on average, three times higher than someone at a healthy weight. We're talking about an extra $9,000 to $10,000 a year just in "excess" medical expenditures.
The Military Problem
This isn't just about healthcare costs or fitting into jeans. It’s a national security issue.

Nearly 1 in 3 Americans between the ages of 17 and 24 are physically too heavy to serve in the military. It’s one of the primary reasons the armed forces are struggling with recruitment. When you can't find enough healthy young people to fill the ranks, the "percentage of obese people in USA" stops being a health stat and starts being a strategic vulnerability.
The Complication: It’s Not Just About Willpower
One thing experts like Dr. J. Nadine Gracia from TFAH keep hammering home is that this isn't just a "eat less, move more" problem.
If it were that simple, we would have fixed it in the 90s.
We’re living in a "pro-obesity" environment. We have food deserts where a head of wilted lettuce costs more than a double cheeseburger. We have "forever chemicals" and microplastics that some researchers think mess with our endocrine systems. We have high-stress, sedentary jobs that basically force us to sit for 10 hours a day.
Even if GLP-1s are "fixing" the weight for 12% of the population, they aren't fixing the environment that caused the weight gain in the first place.
Actionable Steps: Navigating the New Normal
If you're looking at these stats and wondering where you fit in, or how to avoid becoming a statistic, here’s the reality of 2026:
- Check Your Insurance, Not Just Your Scale: With the 2025 policy shifts, 13 states now fully cover weight-loss medications under Medicaid. Many private insurers are following suit, but the "fine print" is getting stickier. Know your coverage before you start a protocol.
- Focus on "Visceral" Fat: The BMI is a blunt tool. It doesn't know the difference between a bodybuilder and someone with a high body fat percentage. Focus on waist circumference. For men, over 40 inches and for women, over 35 inches is where the real health risks (like fatty liver disease) skyrocket.
- The 5% Rule: You don’t need to lose 50 pounds to see a change. Clinical data shows that losing just 5% of your body weight significantly reduces your risk of Type 2 diabetes and can drop your annual medical costs by thousands.
- Demand Better Food Access: If you live in one of the 19 "high-rate" states, the problem is likely systemic. Support local initiatives that bring fresh produce into urban and rural "deserts."
The trend is finally pointing down, but we're a long way from a healthy baseline. The medications are a bridge, not a destination. Whether we can keep the percentage of obese people in USA dropping depends on whether we treat the root causes—the food we eat and the way we live—rather than just the symptoms on the scale.
