Nearly three quarters of U.S. adults are overweight or obese, according to a sweeping new study.
The findings have wide-reaching implications for the nation’s health and medical costs as it faces a growing burden of weight-related diseases.
The study, published on Thursday in The Lancet, reveals the striking rise of obesity rates nationwide since 1990 — when just over half of adults were overweight or obese — and shows how more people are becoming overweight or obese at younger ages than in the past. Both conditions can raise the risk of diabetes, high blood pressure and heart disease, and shorten life expectancy.
The study’s authors documented increases in the rates of overweight and obesity across ages. They were particularly alarmed by the steep rise among children, more than one in three of whom are now overweight or obese. Without aggressive intervention, they forecast, the number of overweight and obese people will continue to go up — reaching nearly 260 million people in 2050.
“I would consider it an epidemic,” said Marie Ng, who is an affiliate associate professor at the Institute for Health Metrics and Evaluation at the University of Washington School of Medicine and a co-author of the new paper.
The paper defined “overweight” adults as those who were age 25 and over with a body mass index at or over 25, and “obese” adults as those with a B.M.I. at or over 30. The authors acknowledged that B.M.I. is an imperfect measure that may not capture variations in body structure across the population. But from a scientific perspective, experts said, B.M.I. is correlated with other measures of body fat and is a practical tool for studying it at a population level.
The authors found a steady increase in the share of people who are overweight or obese over the past three decades.
The rate of obesity in particular rose steeply, doubling in adults between 1990 and 2021 to more than 40 percent — and nearly tripling, to 29 percent, among girls and women aged 15 to 24.

Corporations might be part of the problem, but so are people’s choices. No one is forcing anyone to eat junk food or sit on the couch all day. This constant victim narrative is why nothing gets better. People need to own their actions.
This “personal responsibility” argument ignores the structural barriers many people face. Not everyone has access to fresh, affordable food, and many neighborhoods are food deserts. Addressing obesity means tackling inequality, not just wagging a finger at people.
Personal responsibility is important, but let’s not ignore the cultural factors. Look at how the left’s “everyone’s beautiful at any size” nonsense has contributed to normalizing obesity. We need a return to promoting discipline and healthy living, not this participation trophy culture.
So let me guess: the solution will be another government program that funnels billions to corporations while pretending to care about public health. Fast food giants and Big Pharma must be thrilled.

It’s not just corporations—this is a societal failure. The government needs to step up with real policies, like better food labeling, regulating junk food marketing, and increasing access to healthy options. Obesity is killing us, and it’s preventable.
