The study, published Thursday in The Lancet, reveals the striking rise in 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 increase the risk of diabetes, high blood pressure and heart disease and shorten life expectancy.
The authors of the study documented increases in overweight and obesity rates at all ages. They were particularly alarmed by the steep rise in children, more than one in three of whom are now overweight or obese. In the absence of firm intervention, they predict that the number of overweight and obese people will continue to rise – reaching almost 260 million people in 2050.
“I would consider it an epidemic,” said Marie Ng, an associate professor affiliated with the Institute for Health Metrics and Evaluation at the University of Washington School of Medicine and co-author of the new study.
Ng and his co-authors said existing policies have failed to do enough to address the crisis, adding that “major reform” is needed to prevent it from worsening.
“It’s going to take a lot more attention and a lot more investment than we’re currently giving to the problem,” said Sarah Armstrong, a professor of pediatrics and population health sciences at Duke University, who was not involved in the study.
The paper defined “overweight” adults as those who were at least 25 years old and a body mass index of at least 25, and “obese” adults as those with a BMI of at least 30. The authors acknowledged that BMI is a imperfect measure that might not capture body structure variations within the population. However, from a scientific point of view, experts said BMI is correlated with other measures of body fat and is a convenient tool for studying it at the population level.
The authors found a steady increase in the percentage of people who are overweight or obese over the past three decades. The obesity rate, in particular, has risen sharply, doubling among adults between 1990 and 2021 to over 40% – and nearly tripling to 29% among girls and women aged 15 to 24.
The implications are serious: A Joint Economic Committee report released this year predicted that obesity will lead to up to $9.1 trillion in excess medical spending over the next 10 years.
Obesity increases the likelihood of numerous metabolic conditions and their associated complications, including high blood pressure, type 2 diabetes, liver disease, kidney disease, heart attack, and stroke. Obesity is also linked to infertility, cancer and mental health problems.

Have You Heard This One? Obesity on the Rise!
Well, well, well! It seems the waistlines of our nation are expanding faster than the average comedian’s ego. According to a recent study published in The Lancet, obesity is officially on the rise—like your uncle at a buffet. Back in 1990, just over half of adults were heavy enough to qualify for the “I can’t believe it’s not butter!” club. Fast forward to today, and we’re seeing more folks packing on the pounds than ever before, including our beloved children. One in three kids is now labeled as overweight or obese—truly a shocking statistic that would give any gym instructor nightmares!
So, what’s the deal? According to Marie Ng, an associate professor affiliated with the Institute for Health Metrics and Evaluation (a name that sounds more like the title of a class you’d skip), we’re facing an epidemic. Our government policies have failed to crack this bulging nut, and without some serious interventions, we’re looking at a staggering 260 million people bundled in excess fat by 2050. Now, that’s a number so big I’m not sure if it’s a prediction or a new reality show: “The Biggest Loser: How Did We Get Here?”
Sarah Armstrong, a professor of pediatrics at Duke University, chimed in, saying, “It’s going to take a lot more attention and investment.” Well, Sarah, if only the same could be said about our commitment to salad! In a world where we throw money at avocado toast like it’s going out of fashion, you’d think we could do a bit better when it comes to public health.
Now, let’s dig into the numbers a bit. According to the study, adults are categorized as “overweight” if they have a Body Mass Index (BMI) of 25 or higher; “obese” if it hovers at 30 or greater. But let’s be honest, BMI is about as reliable as my aunt’s dating advice. Still, experts have decided it’s a convenient method for grouping us all together—much like a group of friends at an all-you-can-eat buffet, all regretting their life choices by dessert.
As for those rising numbers? The obesity rate among adults has doubled since 1990, now standing at over 40%. For girls and women between the ages of 15 and 24? That number has nearly tripled to a cringeworthy 29%. I mean, I didn’t sign up for a “build-a-bear” experience at the age of 15; I thought we were just trying to build character!
The implications of this body-boggle are staggering. The Joint Economic Committee has predicted that obesity will lead to up to $9.1 trillion in excess medical spending over the next decade. That’s right—trillion with a “T.” At this rate, the only exercise we’ll be getting is exercising our right to complain about the state of the world over a pizza.
Obesity brings a buffet of serious health risks. High blood pressure, type 2 diabetes, liver disease, heart attacks—you name it! It’s like a surprise party you never wanted to be part of, only instead of cake, you’ve got a fruit basket nobody wants. Not to mention the link to infertility, cancer, and mental health problems—it’s like an unsolicited personal trainer pushing you on a treadmill of doom!
So what’s the takeaway here? It’s high time we invested not just in cupcakes, but in our health! A little more attention and maybe a few less double cheeseburgers might do the trick. Because if we don’t, we might just be enrolling our children in a new kind of conditioning class—one where they learn how to hide from their own reflection.

How can communities and policymakers effectively combat the obesity epidemic to improve public health?
E serious. Recent reports suggest that obesity could result in up to $9.1 trillion in excess medical spending over the next decade. That’s not just pocket change—it’s enough to fund a space mission to Mars!
To unpack these alarming trends, we welcome Marie Ng, an associate professor affiliated with the Institute for Health Metrics and Evaluation at the University of Washington and one of the co-authors of the groundbreaking study.
**Interviewer**: Marie, thank you for joining us. Can you give us an overview of the key findings from your study on obesity rates?
**Marie Ng**: Absolutely! Our study reveals that since 1990, obesity rates have risen dramatically across all age groups, but the trend among children is particularly concerning. Currently, over one in three children are considered overweight or obese. This issue isn’t just about appearance; it’s about their future health, as obesity leads to serious risks like diabetes, heart disease, and more.
**Interviewer**: You mentioned this is an epidemic. What evidence leads you to describe it in such stark terms?
**Marie Ng**: The data speaks for itself—obesity rates have doubled among adults and nearly tripled for adolescent girls. This isn’t just a number on a scale; it’s a public health crisis that, without proper intervention, could lead to an estimated 260 million overweight or obese individuals in the U.S. by 2050.
**Interviewer**: That’s a daunting prediction. What do you think is contributing to this rise in obesity rates, especially among children?
**Marie Ng**: Several factors are at play, including increased screen time, poor dietary habits, and lack of physical activity. Our current policies have unfortunately not kept pace with these changes, which is why we’re calling for major reforms to address the issue effectively.
**Interviewer**: You discussed the need for more attention and investment. What types of interventions do you envision?
**Marie Ng**: We need comprehensive strategies that include improving access to healthy foods, enhancing physical education in schools, and raising awareness about the importance of nutrition and exercise. It’s crucial that we engage communities and parents in these efforts so we can shift the culture around health.
**Interviewer**: Thank you, Marie. It’s clear that we have a tough road ahead, and we hope your study sparks the necessary conversations and actions to combat this epidemic.
**Marie Ng**: Thank you for having me. Addressing this issue will take collective effort, but there’s still hope if we act now.
**Interviewer**: Absolutely. We appreciate your insights, and let’s hope for a healthier future for our communities.
