New Obesity Treatments Show Promise

A research team led by Dr. Ki-young Shin at the Human Care Electro-Medical Device Research Center, part of the Electro-Medical Equipment Research Division at KERI, is making significant progress in developing neuromodulation technology to treat and manage metabolic syndrome.

Metabolic syndrome is a cluster of conditions, including obesity, high blood pressure, and elevated triglycerides, often linked to poor diet and lack of exercise. While various treatments for obesity exist, such as drug injections and pharmaceuticals, these chemical approaches often carry the risk of side effects with long-term use. In response, Dr. Shin’s team at KERI has introduced a new method that involves suppressing appetite by electrically stimulating the cerebral cortex through the scalp.

This technique, known as transcranial random noise stimulation (tRNS), has shown promise in non-invasively targeting the dorsolateral prefrontal cortex to reduce appetite. The research team has identified three key technologies essential for this approach: accurately delivering electrical stimulation to the desired brain area, developing electrodes that can effectively contact the scalp through hair, and creating monitoring systems to ensure the stimulation reaches the target and alters brain activity. Dr. Shin’s team is actively developing these advanced technologies.

To validate the effectiveness of tRNS in suppressing appetite, KERI collaborated with Professor Hyung-jin Choi’s team at Seoul National University Hospital in a clinical trial. This trial involved 60 female participants, divided into two groups — one receiving tRNS and the other an active sham treatment. Over two weeks, each participant underwent six sessions of electrical stimulation, with 20-minute sessions using a barely noticeable 2 mA current. The aim was to demonstrate the potential of tRNS in reducing appetite.

Arrowhead to start two new obesity trials

After wrapping up its work on a cardiovascular candidate in the clinical stage, Arrowhead Pharmaceuticals is now turning its focus to two new obesity treatments, both slated to begin clinical trials in early 2025.

The company introduced two next-generation candidates: ARO-INHBE and ARO-ALK7. These are designed to address obesity and related metabolic disorders.

In preclinical studies, both candidates demonstrated the ability to reduce body weight and fat mass through a novel mechanism of action that could help preserve lean muscle mass, offering a potential advantage over current therapies. Arrowhead plans to seek regulatory approval to start human trials for both candidates by the end of this year, aiming to initiate clinical studies in obesity early next year.

As Dr. Carel le Roux, a metabolic medicine expert from University College Dublin, noted during the investor call:

Weight loss alone isn’t a sufficient value proposition for continuing medication. You need to see health and functional improvements as well.

According to Arrowhead’s chief of discovery and translational medicine, Dr. James Hamilton, when tested as monotherapy and in combination with tirzepatide in diet-induced obesity mouse models, ARO-INHBE and ARO-ALK7 both led to reduced body weight and fat mass while preserving lean muscle mass, resulting in improved body composition. Dr. Hamilton added that with the recent approval and positive clinical impact of new obesity treatments, emerging therapeutic strategies with novel mechanisms of action could represent the future of effective obesity and metabolic disease management.

How Technology Can Help Treat Obesity

Over the past decade, as childhood obesity rates have climbed, digital technology has advanced, offering new avenues in healthcare. The COVID-19 pandemic has accelerated both trends, highlighting the potential of digital health, such as mobile healthcare, to overcome barriers like accessibility and support healthier lifestyles in children.

Digital health, including mobile health (mHealth) and telemedicine, offers new tools for patient monitoring, clinical evaluation, and lifestyle interventions to manage and prevent obesity. These technologies provide personalized support through apps, websites, and devices that promote healthier lifestyles. Let’s take a quick look at how technology can help treat obesity.

A recent, multi-author, lengthy article in Frontiers discusses digital strategies for preventing and treating childhood obesity, evaluating their effectiveness and limitations. The article mentions that in 2020, the National Institute for Health Research (NIHR) launched the “HelpMeDoIt!” app, aimed at supporting weight loss in adults through goal setting, progress monitoring, and social support. However, weight loss interventions for children face additional barriers, including parental time constraints, low socioeconomic status, and lack of awareness. Educating and involving parents to improve children’s lifestyle habits is also a factor.

To explore technological innovations in childhood obesity prevention and treatment, the authors reviewed relevant studies published from 2013 to September 2023 using keywords related to pediatric obesity and digital health. Research was conducted through databases like PubMed and Scopus, and the findings were reviewed and approved by all co-authors.

What are digital health strategies?

Digital health, encompassing digital medicine (DM) and digital therapeutics (DTx), represents a growing field in healthcare. DTx involves software-guided therapeutic interventions to prevent and manage diseases, while DM uses algorithms, software, or hardware to monitor and improve health. The World Health Organization (WHO) defines mobile health (mHealth) as medical practice supported by mobile devices, which can enhance healthcare access, quality, and patient outcomes.

Smartphones, the most common portable electronic devices, have spurred the development of digital tools like apps to manage chronic diseases. Evidence shows that these tools, including mobile apps, web-based tools, and wearable devices, can be effective in preventing weight gain and treating obesity in children and adolescents.

Telemedicine and text messaging

Studies, including randomized control trials (RCTs), have explored its effectiveness through various methods such as phone consultations, video conferencing, and text messaging. While some interventions have led to modest but significant reductions in BMI z-Scores (BMIz), results vary, with some studies showing no significant differences between telemedicine and in-person care.

Text messaging has also been associated with positive changes in health behaviors, such as increased fruit and vegetable consumption and reduced screen time, alongside lower dropout rates in weight management programs. Despite its benefits, telemedicine faces challenges, including high costs, variability in study outcomes, and limitations in generalizing results due to diverse participant demographics. A combined approach of telehealth and in-person visits may offer better outcomes, the authors concluded.

Mobile apps

Studies have shown their effectiveness in promoting weight loss and healthy behaviors, both as standalone tools and in combination with traditional treatments. The apps the authors mention include MetaWell, OBEST, and MINISTOP 2.0. Let’s not forget Dr. Pretlow-designed W8 Loss 2 Go and BrainWeighve either.

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.

Web-based tools and social networks

Online communities, forums, and public health campaigns provide resources and shared experiences that can motivate healthier lifestyle choices. However, the quality of online information varies, with some content being misleading or discouraging.

Videogames

Videogames, traditionally seen as sedentary, are now being leveraged to combat obesity through exergames and serious videogames that encourage physical activity and healthy behaviors.

Exergames like “DDR Dance Dance Revolution” and “Wii Boxing” engage children in physical activity, promoting fitness while playing. Studies show these games can improve body composition, reduce weight, and enhance psychological well-being.

Serious videogames, which focus on nutrition education and behavioral change, have also shown promise. For example, “Food Rate Master” improved children’s ability to distinguish between healthy and unhealthy foods and reduced unhealthy food intake.

Virtual reality (VR) games offer immersive experiences that can motivate physical activity, though more research is needed on their safety and effectiveness for young children. Of course, there’s a caveat — food brands using video games to stealthily promote junk food.

The bottom line

Telemedicine and mHealth tools offer significant potential but require internet access, powerful devices, and user engagement. The success of these tools often depends on patient and family involvement, particularly during the development phase. Parents play a key role in shaping their children’s habits, and their involvement in mHealth strategies is vital.

Further research is needed to understand how digital engagement influences the effectiveness of these interventions. While children are heavy users of technology, it’s important to balance the benefits with the risks, particularly in terms of exposure to subtle marketing tactics through advergames.

GLP-1 Drugs Are Coming in Pill Form

A person is holding two red pills in her hand.

Most of us are aware of injectable GLP-1 drugs for type 2 diabetes and obesity, like Ozempic and Wegovy. However, did you know there are also pill versions of these drugs, with more potentially on the way?

Rybelsus is an oral form of semaglutide, a GLP-1 drug used to treat type 2 diabetes alongside diet and exercise. It is produced by Novo Nordisk, the same company behind Ozempic and Wegovy.

Approved by the FDA for type 2 diabetes since 2019, Novo Nordisk is exploring whether a higher dose of oral semaglutide can be as effective as the weekly injectable Wegovy for weight loss. Eli Lilly is also developing an oral GLP-1 called orforglipron to treat obesity or overweight in adults. Eli Lilly’s phase 2 results show orforglipron, a daily oral nonpeptide GLP-1 receptor agonist, achieved up to a 14.7% mean weight reduction at 36 weeks in adults with obesity or overweight.

Pfizer is entering the oral GLP-1 market with an experimental pill called danuglipron for adults with obesity, intended for daily use rather than the weekly injectables. “Obesity is a key therapeutic area for Pfizer, and the company has a robust pipeline of three clinical and several pre-clinical candidates,” said Mikael Dolsten, M.D., the chief scientific officer and president of research and development at Pfizer.

But will oral GLP-1s change the game and appeal to those turned off by injectables? According to experts, it depends.

Britta Reierson, M.D., a metabolic health and primary care physician and the medical director of Knownwell, said:

I don’t think we’re going to shift away [from injectables] because that wave of interest is already happening… but there needs to be oral options as well… There needs to be a broadened toolkit available because we know that this treatment isn’t one-size-fits-all across the board.

How oral GLP-1s could impact treatment

Oral GLP-1 drugs could improve drug access, especially if refrigeration is an issue, noted Marc-Andre Cornier, M.D., the director of the division of endocrinology, diabetes, and metabolic diseases at the Medical University of South Carolina and president-elect of The Obesity Society. Injectable GLP-1s like Ozempic or Wegovy require proper storage at low temperatures, which can be challenging in certain parts of the world. An oral version could circumvent this issue.

Dr. Reierson added that oral GLP-1s could help address the drug shortage issues common with injectables, as they are generally easier to manufacture. “We need to focus more time and energy on developing GLP-1s in an oral form to make this treatment more sustainable, because there is a crisis in supply and demand with the injectables,” she said.

Aside from supply issues, some people might be deterred by needles or have safety concerns about injections. An oral version of semaglutide could alleviate these worries.

However, Dr. Cornier pointed out that many people who find injectables effective do not mind the needle format and might prefer a weekly injection over a daily pill. For some, a weekly injection could be more convenient than daily medication.

Rybelsus, for instance, must be taken on an empty stomach with no more than 4 ounces of water. Users need to wait 30 minutes before eating, drinking, or taking other oral medications. In contrast, Ozempic can be taken anytime, with or without food.

Cost and side effects remain major factors

Even if the needle is removed, side effects still exist for oral medications. If someone cannot handle the side effects of an injectable GLP-1, an oral pill likely will not solve the problem. “The GI side effects, nausea, vomiting, and constipation…those seem to be across the board. The higher the dosage of the oral medication, the more likely those side effects are,” Dr. Reierson said.

Affordability is also a significant concern. Unless oral medications are significantly cheaper than injectables, access will remain an issue for those needing GLP-1 drugs. Currently, the out-of-pocket costs for Rybelsus are almost the same as for Ozempic.

It makes sense that the drugmakers are rushing to flood the market with currently popular drugs and pave the way for research on new versions in different forms and potency.

Doug Baker, VP of industry relations for The Food Industry Association, said, “In the next few years, we could see anywhere from 12 to 36 million people that could be potentially on this”, noting that FMI has knowledge of 70 different trials in the works at the Food and Drug Administration for new GLP-1 drugs. Also, data gathered from 5,577 U.S. adults in early March for a Gallup poll revealed that 6% of U.S. adults have tried GLP-1 drugs for weight loss, and 3% are currently using them.

Feline Obesity Insights Can Help Humans

GLP-1 receptor agonists and what they can and cannot do took the spotlight on this blog for a while, so it’s been a minute since we’ve written about pet obesity. There’s a study that might be of interest to our readers (more on that below), and even a GLP-1 connection potential. Plus, the pets in this country are still fat and getting fatter, so this topic is not going away and is worth revisiting occasionally.

Fat cats can be useful in studying obesity in humans

Pet cats could serve as valuable animal models for studying the origins and treatments of obesity in humans, according to a new study on feline gut microbes. (The study was recently published in Scientific Reports.) Researchers believe that this research could benefit both cats and humans by improving overall health.

In the study, veterinary researchers analyzed fecal samples from obese cats as they underwent weight loss and maintenance through four dietary phases, including strict calorie reduction. They discovered that the changes in the cats’ gut microbiomes mirrored the dietary effects observed in humans’ gut bacteria. While there is still much to learn, the findings suggest that pet cats could provide significant insights into human gut bacteria and the potential for microbe-based therapies to combat obesity.

Lead author Jenessa Winston, assistant professor of veterinary clinical sciences at The Ohio State University, where the study was conducted, said:

Pets share our environment and even our food, making them naturally occurring disease models with similar exposures to humans… Observing changes in cats related to obesity and type 2 diabetes in humans positions them as excellent models for exploring microbiome-directed obesity treatments… Microbes identified in this study are also common in human studies, despite the dietary differences.

“When the cats were on the weight-loss diet, propionic acid levels rose and remained high, then dropped when they returned to their maintenance diet, indicating a dietary effect,” Winston explained. “This study shows that calorie restriction in obese cats can alter their microbial ecosystem, likely correlating with metabolic outcomes.”

The exact role of the gut microbiome in mammalian obesity remains unclear, but decades of research suggest these organisms and their products are crucial in this complex disease. Findings from feline studies could provide valuable insights for both cats and humans, Winston concluded.

GLP-1 supplements might be coming for your pets

As GLP-1 drugs remain a hot topic, the conversation has now extended to pets. Better Choice has teamed up with Aimia Pet Health to develop a GLP-1 supplement for overweight pets under the Halo brand.

This new initiative aims to address the significant issue of pet obesity, which affects nearly half of the world’s dogs and cats, leading to health complications similar to those seen in humans, such as diabetes, arthritis, and high blood pressure.

The brand states,

Our research and development goal is to replicate the weight loss benefits of leading human brands like Slentrol, Wegovy, Ozempic, and Monjaro, while incorporating protein and nutrients from our Halo products to support lean muscle and overall pet health.

Is it a potentially promising development in the pet healthcare industry, or wishful thinking and an expensive fad? Let’s keep an eye on it.

Unlocking the Potential of GLP-1 Agonists Beyond Diabetes and Weight Loss

Initially developed for diabetes treatment, GLP-1 agonists have gained significant attention for their weight-loss benefits. The success of GLP-1 medications like Ozempic, Wegovy, Mounjaro, and Zepbound has spurred a wave of research exploring their potential beyond diabetes and weight loss.

Discovering secondary uses for GLP-1s

The headlines are coming at us fast and hard. Just in recent weeks, we’ve read that the GLP-1 agonists may help reduce sleep apnea, reduce pancreatitis risk in obese and diabetic patients, reduce rheumatoid arthritis symptoms, and potentially even boost fertility.

In other words, these medications are changing consumer habits and industry dynamics, and people just can’t get enough of them. While the pharmaceutical industry is eagerly investigating new applications for GLP-1 drugs, some think that the real opportunity lies in precision medicine. This approach promises to open numerous commercial pathways and significantly advance personalized patient care.

Why precision medicine?

Elliott Green, the co-founder and CEO of Dandelion Health, which collects and processes clinical data for the healthcare industry, is one of the believers. In a recent article he penned for Fast Company, he opined that, as the COVID-19 pandemic taught us, rapid innovation is crucial for saving and improving lives on a large scale. However, traditional clinical trials, while scientifically rigorous, are not designed for speed and cost-effectiveness.

In Green’s opinion, the challenge is accelerating precision medicine for GLP-1 drugs by applying lessons from the pandemic to achieve near-term, data-driven insights that lead to personalized treatments and care.

Learning from oncology

It’s complicated though. Green writes:

To understand just how “blackbox” GLP-1 drugs are today, one only needs to read or listen to the news. For example, early GLP-1 studies seem to appear daily, and they point to potential issues, such as unwanted side effects in some patients, like psychiatric issues, or opportunities — like GLP-1 agonists potentially being used to treat prostate cancer one day. The key word here? Potential.

With increasing access to data and advancements in AI, healthcare providers should be able to predict which patients will benefit most from specific weight loss drugs. Similarly, pharmaceutical companies should be able to identify new, effective uses for GLP-1 formulations. While progress is being made, it is not happening quickly enough to optimize patient outcomes or confirm new applications for these drugs.

Adopting a proactive approach from oncology, where precision medicine has had a significant impact, could be transformative. Oncologists select treatments based on the genetic profile of tumors. Similarly, GLP-1 drugs could be chosen based on a digital phenotype that predicts the best response with minimal side effects.

Addressing data gaps

The challenge in bringing precision medicine to GLP-1 drugs lies in the lack of real-world data. Although there is more real-world data (RWD) than ever before, much of it remains isolated and unreadable, locked in various systems within healthcare organizations.

RWD often comes from electronic health records (EHR), claims data, and disease-specific registries. However, the most valuable data — unstructured clinical data like waveforms (e.g., ECGs) and imaging data (e.g., MRIs, CT scans) — is typically outside the EHR. This data, which constitutes over 80% of healthcare data, holds immense potential for personalizing GLP-1 care and accelerating drug development. 

Leveraging AI for precision medicine

In Green’s words,

[W]e can take these broad generalizations and turn them into more precise hypotheses to be tested, like: demonstrating GLP-1’s therapeutic effects beyond current uses, including secondary benefits derived from exploratory use or demonstrated with additional data modalities; and developing precision-medicine tools to identify patients with uncontrolled symptoms or to match patients to the right treatment plans.

The bottom line

To advance personalized weight loss treatments, there must be stronger integration of both structured and unstructured health data, and a robust approach to vetting AI algorithms trained on rich, unbiased datasets. This will provide the necessary insights for personalized patient care and help pharmaceutical companies quickly and cost-effectively explore new uses for GLP-1 drugs.

By embracing these strategies, we can drive a more personalized approach to weight loss and unlock new therapeutic potentials for GLP-1 drugs, benefiting patients and the healthcare industry alike.

GLP-1 Drug Makers Go After Counterfeit Versions

In breaking news last week, Eli Lilly is preparing to sue several medical spas and wellness centers for allegedly selling counterfeit and compounded versions of its popular weight loss and diabetes drugs, Mounjaro and Zepbound. This issue has also been raised by Novo Nordisk, the maker of Ozempic, and health organizations, who warn that these fake products can cause serious side effects, including infections.

In an open letter on Thursday, Eli Lilly cautioned against using drugs labeled “research purposes only” or “not for human consumption,” highlighting that federal regulators have not approved oral versions of Mounjaro or Zepbound, despite some pills appearing online.

The counterfeit drugs are said to be unsafe

The company claims that some wellness centers and websites are selling unauthorized versions of these drugs made with unapproved chemicals and marketed as generic versions, even though Lilly does not produce generic versions of its drugs. These counterfeit products are dangerous because they may contain incorrect dosages, wrong medications, no medication, or a mix of several medications, posing serious health risks.

According to Lilly, fake tirzepatide — the active ingredient in Mounjaro and Zepbound — has been found to contain bacteria, high levels of impurities, and different chemicals than genuine drugs. These fake products often have safety, efficacy, and sterility issues.

The FDA does NOT approve

Counterfeiting is not limited to tirzepatide. In December, the FDA warned against using counterfeit semaglutide, the active ingredient in Ozempic and Wegovy, due to potential adverse events such as infections and abdominal pain. Since 2020, the FDA has received over 100 adverse event reports related to counterfeit tirzepatide and semaglutide, including several life-threatening cases, 19 hospitalizations, and at least two deaths.

How to spot a fake

To identify fake GLP-1 drugs, Lilly advised looking for a pink hue in the product (genuine versions are colorless), generic labeling (neither Lilly nor Novo Nordisk sells generic versions), incorrect dosages, grammatical errors on the packaging, lack of tamper-resistant features, and mismatched batch numbers.

The reason for the fakes is to meet the demand

The National Association of Boards of Pharmacy has noted that high demand and short supply of these drugs have led to the sale of substandard and falsified versions, putting patients at risk. Both Wegovy and Ozempic, as well as Zepbound and Mounjaro, have experienced shortages due to high demand. Lilly warned that fake versions of its products are also being sold online and on social media, where it does not sell genuine Mounjaro or Zepbound.

Current steps being taken by the drug makers

In its letter, Lilly also announced legal action against medspas, wellness centers, and clinics selling unapproved and counterfeit versions of its drugs. The company claims these clinics falsely market the fake products as Mounjaro and Zepbound, misuse Lilly’s clinical trial results, and deceptively use the FDA’s approval of genuine drugs to sell the counterfeits.

Lilly has previously filed similar lawsuits and settled with one company, Totality Medispa, which agreed to comply with federal law and report all adverse events to the FDA. Novo Nordisk has also filed lawsuits against nine wellness clinics for selling compounded versions of Ozempic and Wegovy, some of which contained up to 24% impure chemicals. Novo Nordisk is seeking to stop these companies from marketing and selling products claiming to contain semaglutide and is asking for compensation of up to $75,000.

Why Is the Most Recommended Childhood Obesity Treatment Not Readily Available?

For many U.S. parents seeking help for a child with obesity, the most widely endorsed treatment is out of reach — and it’s not the popular GLP-1 agonists like Wegovy, used for weight loss and managing diabetes.

What is the recommended childhood obesity treatment?

Leading medical groups recommend intensive behavioral counseling, spanning 26 hours within one year, to teach children and their families practical ways to eat healthier and be more active. Sounds good, right? A recent Reuters article digs into the reasons these touted programs aren’t easy to find.

And why is not widely available?

These programs are not widely accessible, with wait lists often stretching for several months. They are frequently not covered by health insurance and require a time commitment that many families find challenging, according to interviews with over a dozen doctors and parents.

No treatment option improvement is expected

Consequently, fewer than 1% of the nearly 15 million U.S. children with obesity receive this type of structured care, the U.S. Centers for Disease Control and Prevention (CDC) told Reuters. Efforts by the CDC and other organizations to expand insurance coverage have stalled, doctors involved in the process also told Reuters.

“The coverage for these programs was never good, and we’re not seeing any movement toward improvement,” said Dr. Joseph Skelton, a professor of pediatrics and obesity medicine specialist at Wake Forest University School of Medicine.

No end in sight for curbing childhood obesity

The prevalence of obesity among U.S. children has steadily increased, from 5% in 1980 to nearly 20% now, according to the CDC. It’s also a global issue. New research published by JAMA Pediatrics and based on a review of global studies revealed that the prevalence of obesity increased by 150% in the period covering 2012–2023 compared to 2000–2011, indicating that pediatric obesity and overweight conditions are increasingly common. The problem is getting worse.

This is where the GLP-1 drugs come in

According to new research, the number of young people in the US prescribed GLP-1 agonist drugs, such as Wegovy and Ozempic, for weight loss and diabetes increased by 594.4% over the past three years. The most notable increase in prescriptions was observed among young women and adolescent girls.

Last year, the American Academy of Pediatrics updated its obesity management guidelines, recommending that in addition to behavior and lifestyle interventions for the entire family, weight loss medications are suitable for children aged 12 and older.

Clinical trials involving intensive behavioral programs for children and found that, on average, children lost 5.7 pounds. In contrast, Wegovy and similar drugs have resulted in a more dramatic weight loss — 15% or more of body weight in clinical trials. This significant weight loss, coupled with a lack of insurance coverage for counseling, may lead more families to consider these medications in the future.

Are GLP-1 medications safe for children?

In short, more research is needed. Many doctors and parents are cautious about using the medication due to the lack of data on its potential impact on a child’s development and other long-term risks.

Some doctors argue that increased use of Wegovy among youth will make it even more critical for children to learn healthy eating habits for the long term. They are concerned that relying solely on the drugs could lead to nutritional deficiencies or eating disorders.

Dr. Thomas Robinson, a professor of pediatrics and director of the Center for Healthy Weight at Stanford Medicine Children’s Health in Palo Alto, California, said:

Many of us believe it would make sense to offer behavioral counseling along with the drug. These drugs are very effective at reducing weight and health risks, but you don’t all of a sudden adopt a healthy diet or become more physically active.

GLP-1 Drugs Prompt New Food Offerings

The success of new obesity and diabetes drugs is evident in grocery store aisles. We’ve written before about how the rise of GLP-1 medications is reshaping consumer habits and posing challenges to various sectors of the food and beverage industry.

For one, a Morgan Stanley report predicted that the consumption of sweet and salty snacks could drop by as much as 3% through 2035, causing concern in the food industry. Food companies are reacting accordingly by launching new and reformulated products to cater to the growing number of people using drugs like Novo Nordisk’s Ozempic and Wegovy. Experts believe this trend could significantly alter American diets.

How GLP-1 drugs can lead to nutritional deficiencies

GLP-1 medications, which help reduce hunger and increase feelings of fullness, can lead to nutritional deficiencies because people on these drugs tend to eat less overall. This decreased appetite can result in insufficient intake of essential vitamins, minerals, fiber, and protein.

Specifically, reduced protein intake can lead to muscle loss, while lower consumption of fruits, vegetables, whole grains, beans, seeds, and nuts can limit the intake of important antioxidants, vitamins, and minerals, as well as fiber, which is crucial for blood sugar stabilization, cholesterol management, and digestive health.

To counteract these potential deficiencies, it is important for patients on GLP-1 medications to follow a well-balanced and nutrient-dense eating plan. This includes ensuring adequate intake of macronutrients (proteins for muscle preservation and satiety, carbohydrates for energy and fiber, and fats for vitamin absorption and brain function) and micronutrients (vitamins and minerals). Healthcare professionals recommend tailoring your dietary needs based on personal factors such as age, weight, medical history, and activity levels.

GLP-1-friendly food offerings

Several big food manufacturers stand out. Nestlé, owner of brands like Stouffer’s and DiGiorno Pizza, recently introduced a new line of frozen foods with smaller portions and more protein to counteract muscle loss associated with GLP-1s. This move is seen as a “logical reaction” to the GLP-1 boom, and competitors are expected to follow suit.

The line, called Vital Pursuit, is “high in protein, a good source of fiber, contain[s] essential nutrients, and they are portion-aligned to a weight-loss medication user’s appetite,” the company said. It’s also affordable as it’s sold for $4.99 or less. Items include sandwich melts, pizzas, and bowls with whole grains or protein pasta.

According to Reuters, General Mills is already offering high-protein versions of Annie’s Mac and Cheese and Betty Crocker baking mixes with lower sugar and sodium. And Conagra, which owns brands like Healthy Choice and Slim Jim, is considering smaller-portion frozen foods and sees potential in its protein- and fiber-rich snacks.

Nutrition experts say these new products cater well to GLP-1 users’ needs. These products may also benefit those who stop taking GLP-1s within a year and struggle to maintain weight loss, as well as consumers who are not on GLP-1s but want to reduce calories and sugar or increase protein intake.

A smaller-portion trend

Writer Tina Reed, in her recent article for Axios, reported that Hank Cardello, a former food executive and now a consumer health expert at Georgetown University, suggested that changing perceptions of portion sizes could positively impact American diets. This trend was evident at the recent Sweets & Snacks Expo, where many products were marketed as “minis” or “bites.”

Hank Cardello said:

Once it gets up in that neighborhood, food companies have to pay attention. They have to, otherwise they’re walking away from business. You can’t sell king-size X, Y, and Z to this crowd.

The caveat

Consumers might be misled by marketing claims and assume products labeled for GLP-1 users are inherently “healthy.” Experts emphasize that these drugs should be paired with exercise and a proper diet.

Whether these new products and food trends associated with the increasing use of GLP-1 drugs are here to stay, time will tell. One thing is for sure: Food manufacturers will adapt.

Can Web-Based Self-Help Interventions Help With BED?

A recent JAMA Network Open study assessed the effectiveness of web-based self-help interventions in alleviating binge eating disorder (BED). Here are some details, including the findings and the conclusions.

Why BED?

We’ve covered it many times before, but let’s recall that BED is defined as uncontrolled overeating that can lead to obesity, type 2 diabetes, and hypertension. Prolonged BED can reduce the affected person’s quality of life, negatively impact social relationships, and compromise their ability to perform their job well. Without a timely intervention, BED can become chronic and even lead to premature death.

CBT and its barriers

Some studies have demonstrated that cognitive behavioral therapy (CBT) can serve as an effective BED intervention, as well as positively affect the eating disorders bulimia nervosa and anorexia nervosa.

Unfortunately, some people with BED don’t seek in-person psychotherapy because of such barriers as treatment costs, lack of availability, and sociocultural stigma.

This is where web-based cognitive behavioral interventions come in, thanks to their ease of implementation, availability, reduced social stigma, and cost-effectiveness. This avenue has been growing in popularity for these reasons, making BED treatment more accessible.

About the study

The study involved a randomized clinical trial (RCT) to evaluate the effectiveness of a web-based cognitive behavioral self-help intervention for BED. Researchers measured changes in eating disorder symptoms, well-being, co-morbid psychopathology, self-esteem, emotion regulation, and clinical impairment. Weekly symptom monitoring and ecological momentary assessment (EMA) were used to track real-time changes in binge eating.

Participants were recruited from Germany and other German-speaking regions in Europe. Eligible participants were 18-65 years old, owned a smartphone, and were diagnosed with BED according to the DSM-5 criteria. They were randomly assigned to either a control group (waiting list) or a web-based treatment group. Assessments were conducted at baseline, six weeks (mid-treatment), and 12 weeks (post-treatment).

The intervention consisted of six mandatory modules covering psychoeducation, self-monitoring of binge eating, emotion regulation, and interactive exercises. A sequential module-access strategy was employed to engage participants in a personalized manner.

Study findings

The study found significant changes in BED patterns from baseline to 12 weeks in the intervention group. Out of 1,602 patients, 154 met the eligibility criteria and were recruited, with 77 participants in each group. The intervention group reported fewer binge-eating episodes and showed significant improvements in global eating psychopathology and clinical impairment.

Dr. Priyom Bose, Ph.D., discussing the study results, writes:

“The intervention’s efficacy exceeded or was similar to previously documented digital interventions, as well as in-person guided and unguided self-help interventions for BED.

Notably, the levels of improvement observed in the intervention group were consistent with or surpassed those associated with in-person CBT interventions, thus confirming the clinical applicability of web-based cognitive behavioral self-help interventions.”

The study noted that participants’ motivation, attitudes towards online interventions, demographic characteristics, and treatment expectations influenced the positive effects of the web-based intervention.

The bottom line

The study demonstrates that web-based cognitive behavioral self-help interventions can significantly improve the well-being of people with BED, offering a promising alternative to traditional treatments. However, the study had some limitations, including the under-representation of males and older adults, and potential biases due to the self-report design. Future research can address these limitations through methodologies like double-blind designs.

Will the Cheaper Weight Loss Regimens Replace GLP-1 Drugs?

When patients start on the latest obesity drugs, they often experience reduced food cravings and significant weight loss. However, discontinuing these drugs usually reverses these effects: cravings return, and so does the weight. For instance, within a year of stopping semaglutide — known as Wegovy or Ozempic — people typically regain about two-thirds of the weight they lost. Tirzepatide, marketed as Zepbound or Mounjaro, shows similar patterns. This has led to the medical consensus that these obesity drugs need to be taken indefinitely, perhaps for life.

For pharmaceutical companies selling these blockbuster drugs, collectively known as GLP-1 drugs after the hormone they mimic, this is a lucrative prospect. For patients, who might be paying over $1,000 a month out of pocket, it’s a different story. Most Americans simply can’t afford such ongoing expenses, as a recent article in The Atlantic outlines.

Finding cheaper alternatives

This financial burden has prompted some doctors to get creative, developing regimens that substitute cheaper, though less well-known, alternatives. GLP-1 drugs are highly effective, promoting more rapid weight loss than any other obesity medications currently available.

However, some doctors are exploring whether these drugs need to be used permanently. “What if we use them short-term, for six months to a year, to lose 50 pounds?” asks Sarah Ro, an obesity-medicine doctor and director of the University of North Carolina Physicians Network Weight Management Program. She and other doctors are investigating transitioning patients to older, less expensive drugs for long-term maintenance.

Dr. Ro has already helped hundreds of patients make this switch out of necessity. Many of her patients in rural North Carolina lack insurance coverage for the new obesity drugs and can’t afford them out of pocket. When North Carolina’s state employee health insurance cut off coverage for GLP-1 drugs in April, Ro transitioned her patients to older medications like topiramate, phentermine, metformin, and bupropion/naltrexone, coupled with lifestyle counseling. These alternatives are generally less effective, leading to about half the weight loss of GLP-1 drugs, but are far more affordable, costing as little as $10 a month when prescribed as generics.

Retirees on Medicare lose GLP-1 drug coverage

Jamy Ard, an obesity medicine doctor at Wake Forest University School of Medicine, also had to adjust his approach for patients who lost GLP-1 drug coverage upon retiring and switching to Medicare, which currently does not cover obesity treatments. Doctors like Ard see the need for research on transitioning from GLP-1 drugs to older ones, as many patients will lose coverage at retirement age. “Now I’ve got to figure out, well, how do I treat them?” he said.

Are the alternatives safe?

Long-term data on older drugs are sparse, largely because obesity drugs weren’t profitable enough to justify expensive, long-term studies until recently. Switching from GLP-1 drugs to older medications is largely anecdotal at this point, with varying outcomes. A small minority can maintain their weight with just diet and exercise, while others find the older drugs ineffective. Dr. Ro’s experience suggests that 50% to 60% of her patients have successfully maintained weight loss using older drugs alongside lifestyle changes like cutting out fast food and sugary drinks.

A tailored trial-and-error approach is the way to go

The choice of alternative medication depends on the patient. Different drugs target different biological pathways. For example, the combination of naltrexone and bupropion reduces the pleasure of eating and is particularly effective for emotional eaters. Topiramate makes carbonated drinks unpleasant, which can help soda drinkers. Each drug has different side effects, requiring a tailored approach and sometimes trial and error to find the best fit.

Doctors are also finding that some patients can maintain their weight on lower or less frequent doses of GLP-1 drugs. Lowering the dose doesn’t save money since the pens cost the same regardless of dosage, but extending the time between doses can help stretch supplies.

Stopping completely might be a challenge

Complete discontinuation of obesity medications, GLP-1 or otherwise, is unlikely for most patients. Weight loss triggers compensatory mechanisms in the body, evolved to prevent starvation, making long-term maintenance a constant challenge. Susan Yanovski, co-director of the NIH’s Office of Obesity Research, describes long-term weight maintenance as the “holy grail” of obesity treatment.

The best maintenance strategy — whether it involves GLP-1 drugs, and at what dose — remains an individual question needing further study. “These are really good research questions,” Yanovski said, though they might not align with the pharmaceutical companies’ focus on developing new drugs.

Compounded semaglutide is announced

Hims & Hers company announced last week that it will be selling compounded semaglutide for weight loss at prices significantly lower than Wegovy and Ozempic, addressing a gap in supply. However, it’s important to note that compounded semaglutide is not FDA-approved and undergoes less extensive testing than brand-name drugs.

This compounded GLP-1 drug will be prescribed by physicians through their telehealth platform. Prices start at $79 per month for oral medication kits and $199 per month for injections, much lower than the list prices of Ozempic ($935.77) and Wegovy ($1,349.02).

However, compounded semaglutide differs from FDA-approved drugs like Wegovy and Ozempic in several key ways. Compounded medications do not undergo the rigorous FDA approval process, which ensures safety, efficacy, and quality through extensive testing. This lack of testing can lead to concerns about inconsistent potency, bioavailability, and safety.

Also, these drugs can vary in how they are absorbed and utilized by the body, potentially leading to unpredictable therapeutic outcomes. Safety concerns also arise from the sterility and cleanliness of the compounding process, which might introduce harmful contaminants if not properly managed.

The BrainWeighve app would be an ideal off ramp…

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.”
