Is the U.S. Obesity Epidemic Finally Turning a Corner?

For the first time in more than a decade, there’s a glimmer of hope in the battle against obesity in the United States. According to a recent study published in the JAMA Health Forum, obesity rates in the U.S. have shown a slight but meaningful decline. After years of relentless increases, the percentage of American adults considered obese dropped from 46% in 2022 to 45.6% in 2023 — a small but significant dip that offers a new sense of optimism about the country’s ongoing struggle with obesity.

The study’s findings

For ABC News, Niki Iranpour, M.D., who is an internal medicine resident at New York-Presbyterian/Weill Cornell Medical Center and a member of the ABC News Medical Unit, took a look at the study’s findings and implications.

The study, which tracked the body mass index (BMI) of 16.7 million U.S. adults over a 10-year period, revealed an important milestone. After a decade of rising obesity rates, the average BMI, which reached 30.24 in 2022, plateaued and then slightly decreased to 30.21 in 2023. For many public health experts, this marks the first real sign that the alarming trend of rising obesity may be reversing.

John Brownstein, the study’s co-author, and a professor of pediatrics at Harvard Medical School, expressed cautious optimism about the findings. He said:

What we’re seeing for the first time is that curve is bending and shows a sign of hope for something that was really a threat to American public health for so many years.

While the drop is small, it’s still a hopeful shift in a battle that has been fought for decades. Since the early 2000s, the obesity rate in the U.S. has steadily climbed, contributing to a host of health issues including diabetes, heart disease, and certain cancers. A decline, even a modest one, suggests that something — perhaps multiple factors — is finally starting to make a difference.

The role of semaglutide and GLP-1 medications

While they’re still being evaluated for safety, especially for children, one factor that may be contributing to this positive change is the increasing use of weight loss medications, particularly semaglutide. Semaglutide, the active ingredient in the medications Ozempic and Wegovy, belongs to a class of drugs known as GLP-1 receptor agonists. Originally developed to treat type 2 diabetes, these drugs have been shown to significantly aid in weight loss, making them a game-changer for people struggling with obesity.

Between 2019 and 2023, the use of GLP-1 medications for weight loss increased by a staggering 700%, according to one study published in Annals of Internal Medicine. These drugs work by mimicking a hormone that helps regulate blood sugar and appetite, leading to reduced hunger and weight loss. Given their growing popularity and effectiveness, many experts believe that the widespread use of semaglutide may be helping to turn the tide on the obesity epidemic.

Brownstein and his team pointed out that regions in the U.S. where these medications have been dispensed most — particularly in the South — saw some of the most significant declines in obesity. The South also happens to be a region where obesity rates have historically been high, and the use of weight loss medications is rapidly growing.

Other factors at play

While semaglutide and other GLP-1 medications likely play a key role in the decline, experts caution that there are likely other contributing factors as well. For one, the pandemic had a profound impact on lifestyle habits, and as people returned to more normal routines after the height of COVID-19, some may have become more active and healthier.

Benjamin Rader, an assistant professor at Harvard Medical School and a co-author of the study, suggested that the emergence from pandemic isolation could be influencing this trend. He said:

People are potentially starting to be more active again, stopping the sedentary habits they picked up during COVID… This shift toward more physical activity, combined with a greater awareness of the risks of obesity, may be encouraging healthier choices.

Additionally, the South’s high obesity rate and increased use of weight loss medications were also accompanied by a disproportionately high number of COVID-19 deaths among people with obesity. This tragic impact could have prompted more individuals to seek medical intervention, including weight loss treatments, as a way to manage their health.

A long road ahead

While the findings of this study are encouraging, experts warn against jumping to conclusions. Anne Peters, M.D., a professor at the Keck School of Medicine, emphasized that it’s still too early to determine whether this slight decline in obesity rates will persist in the long term. She told ABC News:

We need to look at this as a positive indicator in a specific database… That may mean that people are doing better and that including therapies [is] helpful, but we need to see how that plays out over time.

Will the trend continue?

As we move into 2025 and beyond, all eyes will be on the U.S. obesity rates to see if this downward trend continues. The increased availability of medications like semaglutide, combined with a renewed focus on physical activity and healthier lifestyles post-pandemic, offers a glimmer of hope that the U.S. may finally be on the road to reversing its obesity epidemic.

For now, the slight decline in obesity rates is a reason to celebrate — but also a reminder that the journey toward healthier habits and improved public health is a long one. The real question is whether this momentary dip will continue into the future or whether the country will face new challenges ahead in the fight against obesity.

Only time will tell.

Are GLP-1 Receptor Agonists Safe for Children?

Weight loss medications like Ozempic and Wegovy are becoming increasingly popular, especially as alternatives to the traditional and often ineffective advice of “eat less and exercise more.” These drugs, known as GLP-1 receptor agonists, have gained favor among adults but are also becoming more widely used by children and teenagers (here’s a good rundown on their types, benefits and side effects).

Adolescent use of GLP-1 medications surges

A recent article published on the MedicalXPress website cites a CDC statistic that roughly one in five children in the U.S. is affected by obesity. And, according to a University of [BLOCKQUOTE] study,  the use of GLP-1 medications among adolescents has surged, with over 30,000 young people aged 12 to 17 taking the drugs in 2023.

Are weight loss drugs safe for children under 12?

Doctors generally agree that addressing obesity early can prevent future health problems, but prescribing weight loss drugs to children brings its own set of challenges. Dr. Chris Straughn, a pediatrician in Dallas, explains that while research indicates that GLP-1 medications can be effective and safe for children and teens, the available studies only track their effects over a few years. As these drugs are relatively new, more time is needed to fully understand their long-term impact.

Wegovy, a version of Ozempic, is FDA-approved for children as young as 12, though it has not been approved for those younger than 12. There are ongoing studies on its use in younger children, and some research on Saxenda (a precursor to Wegovy) shows it can be effective for kids aged 6 to 12. This kind of research is promising for the potential use of GLP-1s in younger patients.

The study, which included 82 participants, found that when children discontinued Saxenda, their BMI began to increase once more. This suggests that to maintain the weight-related benefits as they grow, children may need to stay on the medication. The findings were presented Tuesday at the annual meeting of the European Association for the Study of Diabetes in Madrid and were also published in the New England Journal of Medicine.

Dr. Dan Cooper, a pediatric researcher at UC Irvine, agrees that GLP-1 medications can be useful in certain cases, such as when a child is already developing or has developed diabetes. However, he cautions that the risk-benefit balance is less clear in other children, especially since there is limited research on the long-term effects of GLP-1 use in growing bodies. Puberty is a critical period for bone, muscle, and brain development, and Cooper warns that altering a child’s energy balance during this time could have lasting consequences.

Dr. Cooper reminds parents not to feel ashamed if their child struggles with obesity or weight-related issues. He says,

No one should feel ashamed… Obesity is often driven by biology, and it’s not something to blame yourself or your child for.

The need for alternative solutions

As obesity rates continue to rise, many people are turning to prescription medications like Ozempic for weight loss. However, these drugs come with significant side effects, accessibility challenges, and high costs, highlighting the need for alternative solutions. We’ve discussed them before, including berberine and natural supplements.

A new natural treatment emerges

Researchers at the University of South Australia have developed a new, natural, food-grade treatment for obesity that not only helps reduce weight and improve metabolic health but allegedly does so without the negative side effects commonly associated with other medications.

The new treatment, called InuMCT microcapsules, is made from a combination of plant fiber (inulin) and MCT oils derived from coconut and palm kernel oils. This formulation helps reduce inflammation and improve key metabolic markers, such as blood glucose levels.

In a 21-day study, the InuMCT microcapsules demonstrated several significant benefits:

  • Weight reduction: The microcapsules led to a substantial decrease in weight gain caused by a typical western diet, which is high in fats and linked to obesity.
  • Blood sugar control: Blood sugar levels were reduced by 15%, an important factor in managing both obesity and diabetes.
  • Reduced inflammation: Inflammatory markers dropped by 78%, which is crucial, as inflammation is a major contributor to obesity and related diseases.
  • Liver health: Liver enzyme levels decreased by up to 47%, as high liver enzymes are often associated with poor diet and obesity.
  • Gut health: The microcapsules improved protective gut bacteria by 8.3-fold, supporting the gut lining and helping prevent conditions like “leaky gut syndrome.”

 

Amin Ariaee, a Ph.D. researcher at UniSA, explains that InuMCT offers a natural solution for obesity and related metabolic conditions:

Obesity is a global epidemic with many complex health issues beyond just weight gain… It’s a state of systemic inflammation driven by complex biochemical processes, rather than just excess calories. Unfortunately, current treatments often overlook the role of the gut microbiome, focusing instead on symptoms like weight and high blood sugar. Additionally, anti-obesity drugs can harm the gut microbiome, leading to unpleasant side effects like nausea, stomach pain, and diarrhea, and potentially making long-term inflammation and weight gain worse.”

Our research is different. The InuMCT microcapsules are made from natural, food-grade ingredients that support a healthy gut microbiome, reduce inflammation, and effectively address excess weight. The results have been very promising, both in terms of weight reduction and overall metabolic health.

Study Finds That Weight Loss Drugs Reduce Alcohol Craving

A recent study found that many people using medications for obesity, such as Mounjaro or Wegovy, report a decreased enjoyment of alcohol.

The study, which surveyed WeightWatchers members on obesity medications, found that around half of those who previously drank alcohol reduced their consumption after starting the medication. As was reported by NPR, Tamara Hall, 45, a mother of three, is one such example. She began using Mounjaro in 2023 as part of a WeightWatchers program to manage her obesity and elevated blood sugar. Hall has since lost over 100 pounds, and although she was never a heavy drinker, she now consumes significantly less alcohol.

Hall, whose blood sugar levels have improved, was a moderate drinker who previously enjoyed wine or cocktails at social events. Hall found that her tolerance for alcohol dramatically decreased after starting the medication. One drink would make her feel full and dizzy, an effect she hadn’t experienced before. As a result, cutting back on alcohol was easy.

She said:

I feel amazing… It’s life-changing… I didn’t know it would have this effect — I just don’t crave alcohol anymore, and that’s a huge benefit.

The findings align with a new study published in JAMA Network Open. The study, “Alcohol Use and Antiobesity Medication Treatment,” explored the impact of anti-obesity medications (AOMs) on alcohol use among people in the WeightWatchers telehealth weight management program (January 2022–November 2023). As reported by Medical Xpress, participants had a mean age of 43 and were primarily female (86%). They were prescribed various AOMs, including GLP-1 receptor agonists (e.g., liraglutide, semaglutide), metformin, and bupropion/naltrexone (Contrave).

Of the 7,491 participants who used alcohol at baseline, 45.3% reduced their consumption, while 52.4% showed no change, and 2.3% increased their intake. Those with higher obesity levels and baseline alcohol use were more likely to reduce alcohol consumption. Notably, those taking bupropion and naltrexone had the greatest reduction in alcohol use, likely due to naltrexone’s ability to reduce cravings and rewarding effects, though this effect seemed tied to weight loss rather than the medication itself.

When adjusting for weight loss, the effect of bupropion and naltrexone disappeared, suggesting weight loss as a key factor in alcohol reduction. If AOMs reduce alcohol use through weight loss (e.g., via GLP-1 RAs), adjusting for weight loss might obscure the true contribution of the medications.

Interestingly, the reduction in alcohol consumption was observed across both newer obesity medications like Mounjaro and older drugs like metformin. “What surprised me was that alcohol consumption decreased among people using all types of anti-obesity medications,” says study author Lisa Matero, a health psychologist at Henry Ford Health. One possible explanation is that being part of a weight management program could encourage overall healthier behavior changes.

The study’s results add to a growing body of evidence suggesting that GLP-1 drugs, such as Mounjaro, have wide-ranging effects on behavior. Clinical trials of these medications have shown that participants report changes in their habits, such as drinking less or shopping less. Dr. Robert Kushner, a researcher at Northwestern University, explains that these drugs influence both appetite and the brain’s reward system, which may explain why many people also experience reduced cravings for alcohol.

While research on the topic continues, the findings highlight the potential of weight-loss medications not only for weight management but also for altering lifestyle habits like alcohol consumption. This comes at a time when there’s growing cultural awareness around the benefits of reducing alcohol intake for overall health and wellness.

Experts Continue Evaluating Benefits and Risks of GLP-1 Agonists

As we know, over the past 30 years, rates of overweight and obesity in the U.S. have more than doubled, creating a growing public health crisis. Projections suggest that by 2050, 213 million adults and 43 million children will face overweight or obesity. Researchers have been emphasizing that urgent action is needed to address this issue.

A recent Medscape article looks into one promising intervention that involves glucagon-like peptide-1 receptor agonists (GLP-1 RAs), initially developed for diabetes and now approved for weight loss. These drugs have seen a dramatic rise in popularity, with prescriptions increasing by 132.6% from late 2022 to late 2024. Public awareness has also surged, with 32% of surveyed U.S. adults reporting familiarity with GLP-1 RAs in 2024, compared to just 19% in 2023.

GLP-1 RAs and their effectiveness

GLP-1 RAs, including tirzepatide (which targets additional receptors beyond GLP-1), have demonstrated effectiveness in weight loss. A 2022 analysis of 22 trials involving over 17,000 participants found that 50.2% achieved at least a 5% weight loss, while 17.5% experienced a ≥10% weight reduction compared to placebo. A subsequent 2023 review of 41 trials confirmed significant reductions in weight, BMI, and waist measurements.

Dr. Andres Acosta from the Mayo Clinic highlighted the long-standing use of GLP-1 RAs and the growing enthusiasm for their application in treating obesity. However, experts like Dr. Daniel Drucker from Mount Sinai Hospital caution that while these medications are highly effective, not everyone benefits. Approximately 10% of users may experience minimal weight loss or intolerable side effects.

Dr. Drucker said,

[W]e know some people don’t lose much weight when taking these medicines and others don’t feel well and can’t take them… [It’s} essential for us to identify who will be the best responders, as we do with medications for other conditions, such as cancer and cardiovascular disease.

Understanding obesity phenotypes

Dr. Acosta’s research has identified four obesity phenotypes that can guide treatment approaches:

  • Hungry Gut (HG). Patients experience rapid gastric emptying and feel hungry shortly after meals.
  • Hungry Brain. Individuals have impaired satiety and tend to overeat during meals.
  • Emotional Hunger. Emotional or hedonic eating behaviors dominate.
  • Slow Burn. Patients have a sluggish metabolism and burn fewer calories.

 

In a study of 312 patients, those receiving phenotype-specific treatments achieved significantly greater weight loss (15.9% vs. 9.0%) after one year. Acosta’s lab has developed a genetic test to predict the best responders to GLP-1 RAs, showing promise in identifying individuals who might benefit most. It’s licensed by Dr. Acosta’s lab and available through Phenomix Sciences.

His group has also studied which lifestyle interventions are most effective for each phenotype. Dr. Acosta said,

When a unique lifestyle intervention targeting each phenotype was applied, patients lost more weight and had greater metabolic improvement.

Concerns about side effects

Despite their benefits, GLP-1 RAs carry risks. Common side effects include nausea, diarrhea, and constipation, while more serious issues like pancreatitis and gallbladder diseases have been reported. Additionally, cases of compounded GLP-1 RAs from pharmacies have been linked to fatalities. These risks emphasize the need for cautious use, especially as discontinuation rates are high due to cost (over $12,000 annually) and side effects.

Optimizing treatment

Experts like Dr. Marc-Andre Cornier stress that GLP-1 RAs should be part of a broader strategy that includes lifestyle changes, such as a high-protein diet and resistance exercise to prevent muscle loss. Furthermore, precision medicine approaches tailored to individual phenotypes may enhance treatment success and minimize trial-and-error prescribing. Recently published recommendations can help healthcare experts guide patients taking GLP-1 RAs to optimize nutrition.

Public attitudes and sustainability

Despite rising interest, a recent survey found that most Americans prefer alternative methods, such as plant-based diets, over weight-loss injections. Moreover, many discontinue GLP-1 RAs within a year, raising concerns about long-term effectiveness and potential weight cycling.

Dr. Acosta highlighted the importance of identifying ideal candidates for these medications to maximize benefits while addressing cost and insurance coverage challenges. Tailored approaches are key to ensuring sustainable, effective obesity treatment.

What Doctors Say About Prescribing GLP-1 Receptor Agonists to Kids

Yesterday, MedPage Today published another part of its series called “Ozempic: Weighing the Risks and Benefits.” In the piece, Enterprise & Investigative Writer Sophie Putka examines how often doctors prescribe new weight loss drugs to kids and interviews a few professionals about their thinking process, reservations, and concerns.

As enthusiasm for GLP-1 receptor agonists as a weight-loss solution has grown, their use in children has also increased. Currently, liraglutide and semaglutide are the only GLP-1 drugs approved by the FDA for treating obesity in children aged 12 and older.

Between October 2022 and September 2024, prescriptions for these two medications by pediatric and adolescent medicine specialists surged from 3,448 to 24,435 — a sevenfold increase in just two years, according to a MedPage Today analysis of Symphony Health data. During this time, total prescriptions for all GLP-1 drugs written by these specialists more than doubled, rising from 59,868 to 125,538. These figures include prescriptions for 11 GLP-1 brands, many of which are approved for type 2 diabetes, but exclude those written by primary care or family medicine physicians and compounding pharmacies.

Many specialists feel cautiously comfortable prescribing GLP-1 medications to children when other options have been exhausted, provided that families are engaged in lifestyle interventions. However, concerns remain about long-term effects, particularly on bone density, and some experts remain uneasy about the rapid adoption of these drugs in pediatric care.

The jury is still deliberating

According to a recent article in Scientific American, written by Lauren J. Young, an associate editor for health and medicine, experts express concerns about potential impacts on bone health, growth, puberty, and restrictive eating habits, emphasizing the need for long-term studies like this JAMA study. These medications, considered lifelong treatments, pose unique challenges for teenagers compared to adults. Here at Childhood Obesity News, we also covered all kinds of questions and concerns regarding the potential risks of pediatric, adolescent, and adult use of GLP-1 drugs.

Still,

Clinical trials in younger age groups have shown significant weight and BMI reductions compared to lifestyle changes like diet and exercise, leading to FDA approvals of liraglutide (Saxenda) in 2020 and semaglutide (Wegovy) in 2022 for children 12 and older. A recent study reported a nearly 600% increase in GLP-1 prescriptions for adolescents and young adults between 2020 and 2023, largely driven by Wegovy’s approval for weight management in late 2022.

Proceeding with care

Last year, the American Academy of Pediatrics (AAP) issued an updated Clinical Practice Guideline for recommending the use of pharmacotherapy for adolescents 12 and up, including GLP-1 agonists.

Sarah Hampl, M.D., of the University of Missouri-Kansas City School of Medicine and lead author of the AAP guidelines, emphasized the role of other interventions that accompany medication. She said:

It was recommended, not in isolation or not as a monotherapy, but as adjunct or addition to intensive health behavior and lifestyle treatment… [AAP] needed to comment on [pharmacotherapy], because it can be a very effective form of treatment — again, as an adjunct and these kids, especially with severe obesity, they have some really serious and real comorbidities right here and now, in their childhood.

On the other hand, Dr. Fatima Cody Stanford, a pediatric obesity specialist at the Massachusetts General Hospital in Boston, avoids prescribing GLP-1 drugs to children under 12.

She said:

I would still probably use my other drugs where we do have some data, like a topiramate or metformin, or if they have very severe obesity, I would wonder if they had something else,” such as proopiomelanocortin (POMC) deficiency or leptin receptor deficiency.

Dr. Stanford ensures her adolescent patients receive comprehensive care, including dietitian support and psychological counseling, while closely monitoring bone health given the lack of long-term data on GLP-1 use.

It looks like family medicine doctors tend to use weight-loss drugs as a last resort. Dr. Tochi Iroku-Malize, former board chair of the American Academy of Family Physicians, noted that while medications might be necessary for some children with severe obesity, their long-term effects on developing bodies remain unclear.

She said:

When we’re starting with children, they have a longer way to go than adults when it comes to using these medications… [W]e don’t yet know what the long-term effects of taking the weight-loss medications are, and whether the young patients would have to continue taking them indefinitely to maintain their weight.

Despite these challenges, experts agree on the importance of combining medication with healthy lifestyle habits, stressing that the long-term success of any treatment relies on addressing the broader environmental and behavioral factors contributing to childhood obesity.

Gene Therapy for Childhood Obesity

Childhood Obesity News has been looking at various types of treatment for childhood obesity, including GLP-1 agonists, digital technology, and behavioral interventions. Now, let’s take a quick look at yet another promising treatment — gene therapy.

For the past four years, researchers at Shriners Children’s St. Louis have been exploring new methods to combat the impacts of childhood obesity. Led by Farshid Guilak, Ph.D., and Ruhang Tang, Ph.D., the research team has developed a promising approach using gene therapy. Their studies in mice have shown that this therapy can convert harmful fatty acids into beneficial ones, which may help children with obesity lower their risk of associated health problems, particularly arthritis.

The study, published in the Proceedings of the National Academy of Sciences, details a gene therapy technique called “fat-1 gene therapy,” which prevents metabolic dysfunction, cellular aging, and arthritis linked to obesity.

According to Dr. Guilak, excess weight is the top preventable risk factor for arthritis in children. The team’s findings highlight that it’s not only obesity itself but also the diet that contributes to arthritis risks. Specifically, the type of fatty acids children consume significantly affects their weight and health.

Dr. Tang explained that gene therapy involves using an adeno-associated virus (AAV) to introduce a gene coding for an enzyme into cells. This enzyme automatically transforms pro-inflammatory Omega-6 fatty acids into Omega-3 fatty acids, which are healthier for metabolism. Omega-3s — found in foods like fish and certain nuts — enhance metabolic health by improving insulin sensitivity, promoting fat breakdown, and reducing inflammation, potentially lowering the risk of diseases related to obesity. Natalia Harasymowicz, Ph.D., another study leader, noted that the therapy also reduces the number of inflammatory cells involved in obesity and arthritis.

The study specifically examined post-traumatic arthritis, a form common among children due to injuries such as knee meniscus tears. A single gene therapy injection was shown to significantly reduce the negative effects of a high-fat, Omega-6-heavy diet on both metabolic health and knee arthritis. The therapy also appeared to prevent early “aging” in the mice caused by diet-induced obesity.

Dr. Guilak said:

What we are observing is that obesity results in old knees in young patients… The modern diet, especially in the United States, tends to be high in Omega-6s and low in Omega-3s, which can lead to an imbalance, especially for kids… Arthritis can be a very painful and debilitating condition for children so we’re hopeful that this research will help reduce the risk of it developing and make treatments more effective. The implications for how this research might be used in the future are vast but we’re excited about the potential for it to help kids lead healthier lives.

The research team, led by Dr. Guilak, is now collaborating with the FDA, aiming to start clinical trials within the next three to five years.

Digital Technology Can Help Reduce Obesity

We continue looking at the role of digital technology in improving pediatric care. Two recent studies, both published in JAMA, found that adding a digital component to health counseling — even something as simple as a text message — may help reduce childhood obesity.

One study, funded by the Patient-Centered Outcomes Research Institute, used REDCap data tools hosted by Vanderbilt University Medical Center, with support from the National Institutes of Health. It was co-led by Dr. Eliana Perrin, a Bloomberg Distinguished Professor of Primary Care at Johns Hopkins University.

Text messages as a tool against obesity in infants

Dr. Perrin and her team developed the Greenlight Program, an initiative designed to educate parents about promoting healthy growth in infants. With most parents owning smartphones, this digital program is easily accessible.

The researchers recruited nearly 900 parent-infant pairs from hospitals and pediatric clinics at six different medical institutions. All participating infants were 21 days old or younger, born after 34 weeks of pregnancy, at a healthy weight, and without chronic conditions affecting weight gain.

Participants were divided into two groups. Both groups received Greenlight Program materials, which included counseling on nutrition and healthy habits, as well as age-appropriate booklets with goal-setting advice. However, only half of the group received interactive, personalized text messages from an automated system. These texts offered immediate feedback, tips for addressing challenges, and words of encouragement as they made progress.

The impact of text messages

The study tracked the outcomes of the text messages on childhood obesity until the children reached two years old. Researchers measured various health metrics, including weight and growth, to evaluate the program’s success. Through regular followups and digital monitoring, they could capture a comprehensive view of each child’s development.

Results showed a marked improvement in maintaining healthy growth patterns in children whose parents received the personalized texts. Between the two groups, children of parents who received digital support had healthier growth trajectories over their first two years compared to those who received only counseling.

The digital program led to a 45% relative reduction in obesity. Researchers found that the benefits of the digital intervention began as early as four months and continued over the two-year period, marking this study as one of the first large-scale efforts to prevent early childhood obesity.

Dr. Perrin said:

If we can prevent obesity in these children at the highest risk, we can also work toward greater health equity.

Implications for broader applications

The success of this study suggests that similar text-based interventions could be adapted to address other age groups or health issues. Digital technology offers a scalable way to deliver health education tailored to individual needs and support in real-time. The duration and size of this groundbreaking study adds confidence that the outcomes are not a coincidence.

Another study focuses on diversity

A recent study published in JAMA focused on infants coming from diverse racial and ethnic backgrounds. Called Greenlight Plus, the trial randomized 449 parent-child pairs to the digital intervention group and 451 to the counseling-only group. The study included 45% Hispanic children, 20.6% non-Hispanic White, 15.9% non-Hispanic Black, and 18.3% identifying as other or mixed races. Among parents, 65.2% preferred English and 34.8% preferred Spanish; 15.6% reported food insecurity, and 55.6% had limited health literacy.

Results showed a lower mean weight-for-length in the digital intervention group compared to the counseling-only group. Although the proportion of children classified as overweight was similar between groups, the digital intervention group had a significantly lower obesity rate (7.4% vs. 12.7%).

The authors noted that some population groups were not well represented in the study and that only English and Spanish speakers were included. Nonetheless, they highlighted the potential for a meaningful population-level impact if the intervention is scaled up, suggesting further studies on broader implementation.

Finally, a quick reminder about Dr. Pretlow’s app and an upcoming study geared at teens. The ability to rechannel displacement into less harmless activities rather than succumbing to urges is behind the behavior modification app, BrainWeighve, currently ramping up for a trial through the University of California Los Angeles (UCLA). The trial focuses on weight loss for obese teens using a self-directed, physician-supervised program withdrawing from one problem food at a time.

Halloween Tips and Tricks to Minimize the Candy

With Halloween only one day away, let’s take a quick look at the advice pediatric obesity experts are giving to minimize — or at least control — the deluge of candy. Between the parties and trick-or-treating it’s very possible for parents and guardians to lose track of how much candy and processed, unhealthy food the kids are eating.

However, with these tips, parents streamline the fun without having kids overindulge. Yes, much of this advice is obvious — and it’s easier said than to follow — but it’s worth revisiting. In an interview with Fox News Digital, Dr. Dyan Hes, medical director at Concorde Pediatrics of Northwell Health in New York City, along with a few other experts, shared these tips.

Don’t banish all candy, set limits

Dr. Hes rightly pointed out that families that are overly strict about candy consumption can lead to kids sneaking “forbidden food.” Instead, set the limit on how many pieces of candy your child or children can have on Halloween night and any satellite events and parties.

The Fox News Digital article author, Lifestyle Reporter Angelica Stabile writes:

The American Heart Association recommends that kids don’t consume more than 25 grams of added sugar per day.

That’s the equivalent of about four to five mini Milky Ways, three fun-size Snickers or three bags of M&Ms, according to registered dietitian nutritionist Ilana Muhlstein.

“Knowing there’s a clear and fair allotment ahead of time will minimize any friction later on,” the Los Angeles-based expert told Fox News Digital.

“It will also encourage them to prioritize their favorite candies, eat them more slowly and savor them more mindfully,” she went on.

“It’s a great opportunity to demonstrate moderation and balance.”

Dr. Hes also suggests storing leftover candy out of sight after Halloween and give out only two treats max per day (the fewer the better). Even better, donate the candy.

Serve balanced meals

Before trick-or-treating, serve your kids healthy, nutritious food with plenty of veggies, protein, and fiber. You can have fun with it, too, by keeping the Halloween theme throughout. Muhlstein told Stabile:

This will help the kids feel full, balance their blood sugar levels, improve their energy and reduce the likelihood of overindulging in candy later on.

“Treats” don’t have to be just candy

Treats don’t equal only candy. Think about getting or giving out trinkets, stickers, temporary tattoos, toys, and other items.

Muhlstein said:

It’s a great way to help your kids foster a healthy relationship with the holidays, so they see that there are more ways to treat yourself and celebrate, beyond food.

Consider non-candy activities

Whether you are hosting or attending a party, instead of filling up on candy, think about activities that involve movement, like a dance party, a costume fashion show or a contest, or a scavenger hunt. Not into that? Suggest a DIY art project (the internet is full of themed suggestions, with printable instructions and handy materials).

To quote Muhlstein again:

Alternative celebrations like these also help prevent the risks of overindulging in sweets, including upset stomachs, hyperactivity and cavities.

Think about gut health

In his article for The Conversation, gastroenterologist and gut microbiome researcher at the University of Washington School of Medicine Christopher Damman also warns to stay away — or at least limit — sugar-laden treats, choosing more microbiome-friendly offerings:

Not all Halloween treats are created equal, especially when it comes to their nutritional value and effects on gut health. Sugar-coated nuts and fruit such as honey-roasted almonds and candy apples rank among the top, offering whole food benefits just beneath the sugary coating. Packed with fiber and polyphenols, they help support gut health and healthy metabolism.

On the opposite end of the spectrum are chewy treats such as candy corn, Skittles, Starbursts and Twizzlers. These sugar-laden confections are mostly made of high fructose corn syrup, saturated fat and additives. They can increase the unsavory bacterial species in your gut and lead to inflammation, making them one of the least healthy Halloween choices.

Pure chocolate candy, especially dark chocolate, are a better option than candy that contains only a small amount of chocolate (we’re looking at you, Twix, Three Musketeers and Milky Way).

Well, there you have it. Hopefully, armed with this expert advice, you’ll have a fun, safe Halloween!

How Thinking on Obesity Has Shifted Over Time

Over the years, the way society thinks about obesity has undergone a profound transformation. What was once viewed as a simple issue of personal responsibility has now evolved into a more nuanced understanding of a complex, chronic condition influenced by various factors beyond individual control. This shift in thinking has far-reaching implications for public health, healthcare, and the well-being of individuals living with obesity.

From personal failure to a complex condition

For much of recent history, obesity was seen as the result of poor lifestyle choices — too much food and too little exercise. It was commonly viewed as a moral or personal failing, with public health campaigns often focusing on slogans like the “war on obesity” or the “obesity epidemic.”

These messages reinforced harmful stereotypes of larger-bodied people as lazy or lacking self-control. As a result, many people with obesity experience stigma, discrimination, and shame, not only from society but also within the healthcare system. (We’ve written plenty about fat shaming alone over the years.)

This narrow view of obesity failed to consider the broader range of factors that contribute to weight gain. In recent years, research has increasingly shown that obesity is influenced by a variety of complex factors, including genetics, socioeconomic status, psychological well-being, medications, and the environment. While diet and physical activity remain important, they are only part of the puzzle.

Is the word “obesity” offensive?

A recent article for The Conversation, “How we think about ‘obesity’ and body weight is changing. Here’s why,” Executive Editor Stephen Khan used the word “obesity” with an asterisk (“ob*sity”) throughout his article, explaining,

Historical reflections on the word “obesity” reveal its offensive origins, with advocates suggesting the term ob*sity should be used with an asterisk to acknowledge this. To show our respect, we will adopt this language here.

He also noted that in 2014, the American Medical Association classified obesity as a chronic disease, sparking debate about whether this label pathologizes natural body changes and fuels discrimination.

Why we should fight stigma

A lengthy article by the American Psychological Association by Zara Abrams cites plenty of research to back up the notion that stigma can lead to serious consequences in the person’s physical and mental well-being, quoting a few experts, including Sarah Novak, Ph.D., an associate professor of psychology at Hofstra University in Hempstead, New York, who says,

There’s a perception that weight stigma might feel bad but [that] it’s tough love and it’s going to motivate people… But research shows that this isn’t true.

Citing this and this research on the subject, Abrams writes,

Like other forms of bias and discrimination, weight stigma, also called sizeism, leads to suffering and psychological distress. Sizeism increases a person’s risk for mental health problems such as substance use and suicidality.

Perception of sizeism has been difficult to change

Sizeism is one of the most deeply entrenched stigmas in today’s society, partly because of “sociocultural ideals tying thinness to core American values such as hard work and individualism.” Abrams also notes that “weight-based bullying is more common than bullying based on race, sexual orientation, or disability status” among children, according to some research results published in the Journal of Adolescence. Sadly, family members are “high on the list of perpetrators.”

Psychologists have tested various interventions to reduce sizeism, including empathy-building and education about body weight. However, these approaches have had little effect on anti-fat biases. Unlike racism and sexism, weight discrimination remains legal in most places, with only a few states and cities banning it. This lack of legal protection allows weight-based discrimination in hiring, promotions, and wages to persist. Though public support exists for stronger protections, policy changes have been slow.

Shifting public health approaches

As our understanding of obesity has grown, so too has the way public health professionals approach the issue. The previous weight-centric model — where weight loss was the primary health goal — has come under scrutiny. Many experts now believe that focusing solely on weight loss can lead to negative outcomes, including weight cycling (repeatedly losing and regaining weight), increased stigma, and negative mental and physical health effects.

In response, a new weight-inclusive approach to health has gained momentum. This perspective promotes healthy behaviors — such as balanced eating, regular physical activity, and mental well-being — regardless of whether they lead to weight loss. This approach aims to reduce the harm caused by weight stigma and support people in improving their overall health, rather than fixating on a number on the scale.

The role of healthcare providers

Healthcare providers play a critical role in how obesity is addressed in medical settings. Historically, larger-bodied patients often experienced weight bias, even from their doctors. This stigma can lead to worse health outcomes, as patients may avoid seeking care or feel blamed for their condition rather than supported.

Today, there is a growing recognition of the need for more compassionate and inclusive care. Health professionals are encouraged to use person-first language (e.g., “person living with obesity”) to avoid reducing individuals to their weight. Additionally, clinicians are urged to shift their focus from weight to health behaviors, helping patients set goals around physical activity, nutrition, and mental well-being without making weight loss the central objective.

How Are Weight Loss Medications Covered Globally?

We’ve been following the developments in the realm of GLP-1 agonists for a while now, including their potential to treat various conditions, risks, and availability. Let’s take a quick look at the recent headlines.

France is the latest European nation to decide against covering weight loss medications through its national insurance program. While the anti-obesity drug Wegovy is now available in the country, the French government is not offering enthusiastic support for it.

Novo Nordisk, the Danish pharmaceutical company that also manufactures the popular diabetes drug Ozempic, announced that Wegovy is now on sale in France for individuals struggling with obesity. According to a company representative, 10,000 people in France have already accessed the drug through an early access program.

Wegovy is expected to cost patients between €270 and €330 per month, but France’s national health insurance won’t cover the cost, meaning users will need to pay out-of-pocket. The drug is recommended only as a secondary option for those whose weight loss efforts through diet and exercise have failed.

Additionally, France’s drug safety agency mandates that initial prescriptions for Wegovy must come from an obesity specialist to prevent misuse, such as by individuals without weight-related health problems who may seek it for cosmetic purposes.

Elsewhere in Europe

Despite the widespread popularity of these anti-obesity drugs, which are predicted to generate global sales of $131 billion (€117.4 billion) by 2028, there have been shortages in the European Union since 2022. However, some experts, such as Dr. Jens-Christian Holm from Denmark’s University of Copenhagen, remain skeptical.

Dr. Holm said that the medications are “not the Holy Grail,” adding:

There are problems there. They cost a lot of money. There are side effects, and they are not working when you stop using them.

France is not alone in its cautious stance. For example, Germany’s national health system is prohibited by a 1980s law from covering drugs aimed at “lifestyle” conditions like obesity, smoking cessation, or hair loss. Therefore, while Wegovy has been available in Germany since 2023, only privately insured patients or those who pay out-of-pocket can access it, with the highest dose costing €302 per month.

In Denmark, where Novo Nordisk is based, the drug is also not typically covered. The Danish health authority has estimated that it would cost around 6 million Danish kroner (€805,000) to prevent a single cardiovascular event, a major factor in its decision not to cover the medication.

Meanwhile, in the United Kingdom, the health service recommends that Wegovy be used for a maximum of two years, refusing to fund longer-term use due to concerns about its cost-effectiveness. Given that many patients regain weight after stopping the medication, there is an ongoing debate among researchers, policymakers, and pharmaceutical companies about extending this usage period.

Wegovy is also available in other countries such as Norway, Spain, Switzerland, Italy, Iceland (where usage “increased by more than twenty-fold in five years,”) Australia, Brazil, Canada, Japan, the U.S., and the UAE, with further international launches planned.

Some nations are waiting to observe the effects of the drug before introducing it. For instance, while Wegovy is not yet available in the Netherlands, Dutch officials are already wary of the potential financial strain. Last year, Novo Nordisk requested that Wegovy be included in the Netherlands’ basic health insurance program. However, a government advisory panel expressed concerns in July about the drug’s long-term effects and the potential €1.3 billion annual cost, deeming it “socially irresponsible.”

These financial concerns might shift in the future, as Novo Nordisk has indicated that it could offer flexible pricing to encourage broader adoption of the drug. Additionally, new medications entering the market in the coming years could help reduce prices.

A Novo Nordisk spokesperson told Euronews Health that the company is continuously exploring ways to collaborate with healthcare systems to make its products more accessible, particularly for patients with significant unmet needs.

The U.S.: cost vs. benefits

Also in recent news, according to the U.S. Congressional Budget Office (CBO), the cost of paying for obesity drugs would be greater than the economic benefits. The CBO estimates that Medicare would spend $35 billion more on obesity drugs from 2026 to 2034, but the savings from improved health would be small.

Here are some details from the CBO’s analysis:

  • The CBO estimates that the federal government would pay an average of $5,600 per user in 2026, and $4,300 per user by 2034.
  • The CBO estimates that the savings from improved health would be less than $50 million in 2026, and increase to $1 billion in 2034.
  • The CBO projects that expanded use of obesity drugs would improve beneficiaries’ health, mainly by reducing the incidence of obesity-related chronic diseases.
  • The CBO continues to monitor trends in the use of obesity drugs, including their prices, effects on health, and coverage by insurance plans.
