As Popularity of Weight Loss Medicine Soars, Professionals Caution Against “Magic Pill” Mindset

A growing weight-loss fad has been dominating headlines this summer.


No, it isn’t a new type of trendy diet, exercise regimen or social media influencer-touted superfood. It’s two medications – Ozempic and Wegovy – that have skyrocketed in popularity as more Americans turn to these once-weekly injections to aid in their weight loss efforts.


But, while acknowledging the drugs’ effectiveness, their intended patient populations and appropriate usage has become far more nuanced and situational, and the intended outcome of long-term weight loss and health is dependent on more than just taking either of these medications once a week.


“While these medications can be helpful for some people who struggle with weight loss, it's important to remember that they are not a magic solution,” said Rebecca Shenkman, MPH, RDN, LDN, director of the MacDonald Center for Nutrition Education and Research at Villanova University’s M. Louise Fitzpatrick College of Nursing.


First, it’s important to understand the components and histories of both Ozempic and Wegovy. They are prescription medications of the same drug, semaglutide, which belong “to a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists, originally developed to treat type 2 diabetes,” per Shenkman. It was discovered by researchers that significant weight loss was a side effect of semaglutide.


Ozempic is the 2017 FDA-approved drug used to help treat diabetes. Currently, it is not FDA approved for weight loss and typically not covered by health insurance when used for that purpose, per Shenkman, but is often prescribed off label for “weight management in certain individuals who do not have diabetes, but struggle with obesity or [are] overweight.” Wegovy was approved by the FDA in 2021 as an anti-obesity drug used for individuals living with obesity or individuals with excess weight, but not classified as living with obesity, who also have other associated health problems.


“When used correctly, the drugs can have many benefits,” Shenkman said. “[Semaglutide] is shown to improve diabetes and body weight in addition to seeing improvements in cardiovascular health and risk factors.”

However, “correct use” is what concerns Shenkman and other health and nutrition professionals.


“Anti-obesity drugs are a valuable tool for people who have not experienced adequate benefit from self-directed or professionally directed lifestyle treatment,” she said. “However, what we are seeing more and more of now is that people are requesting anti-obesity medications without meeting eligibility criteria for drug use, [such as] body mass index and weight criteria, [or] having the foundational knowledge and application of healthy lifestyle behaviors prior to medication use.”


To Shenkman’s first point, there are several factors, especially in American society, driving those who may not meet the criteria for these medicines or even truly need them to request and ultimately receive the drugs.


The media’s portrayal of ideal body image is an enormous influence, which can lead to “body dissatisfaction and a desire for quick weight loss solutions,” said Shenkman. Advertisements for these drugs often promote those ideas, and even downplay side effects, making them more appealing.


Intrinsically tied to body image is the struggle many individuals have with psychological issues related to food, such as emotional or binge eating.


“They feel that their self-worth is tied to their weight, and they will do almost anything to lose weight, whether it be five or 50 pounds.” Shenkman said. “These individuals might believe that medication will help them control their eating habits more effectively.”


Identification of such issues prior to prescription approval is something that providers need to be aware of and screen for, Shenkman said.


“It is so important for providers to complete a comprehensive pre-treatment assessment of their patients who start on weight loss medications. Unsupervised or improper use can lead to malnutrition, unhealthy weight loss, or even a worsening of an undiagnosed and/or undertreated eating disorder or mental health condition.”

But even users who meet all pre-treatment criteria may be turning to the drugs in haste, or believe that they alone will solve their problems, and do so quickly.


“Americans are known for having that ‘quick-fix mentality’ where people often seek quick solutions to their problems, including weight loss,” Shenkman said. “Weight loss medications might promise faster results compared to lifestyle changes, which can take time and dedication.”


Compounding this “quick-fix mentality” is the frustration many feel when they fail to see results after multiple unsuccessful attempts at weight management.

“The abundance of information on diets, exercise routines, and weight loss programs can be overwhelming… Some may turn to medications as they seem more straightforward and require less effort to understand,” explained Shenkman.


But, as health care providers know, they are far from straightforward. All drugs, including Ozempic and Wegovy, come with the potential for side effects, which can vary with the individual. Headlines this summer focused on reports of users experiencing gastroparesis, described by Shenkman as the “the slowing down or ‘paralysis’ of the digestive system and gastric (or stomach) emptying.”

Though most often reported to cause nausea and vomiting, complications of gastroparesis can be quite serious.


“If someone continues the medication and experiences chronic gastroparesis, complications to be aware of include malnutrition, dehydration, acid reflux, blood sugar control and even bowel obstruction,” Shenkman said.


The American Society of Anesthesiology also recently issued guidance on the use of such drugs prior to surgery, given potential life-threatening complications.


“When prescribing anti-obesity medication, it is the responsibility of healthcare providers to inform patients about potential side effects and risks associated with the medication,” Shenkman said. “It is also the right of the patient/consumer to ask questions and understand what they are putting in their body. A thorough discussion about benefits and possible adverse effects can help patients make informed decisions about their treatment.”


Many users may also not fully understand that these drugs are usually taken long-term, even after reaching a desired weight. Stopping without the knowledge of how to keep the weight off may lead to its return. Considering the pros and cons of the drugs, Shenkman’s advice is simple.


“Weight loss medications should always be used as part of a comprehensive weight management plan, which includes a balanced diet, regular physical activity, and lifestyle changes. Relying solely on medications without addressing other aspects of weight management is not likely to lead to long-term success no matter how long you stay on a medication.”

Biden’s Acts of Clemency Raise Awareness of the Power and Embolden Those Seeking a Second Chance, Villanova Law Professor Says

Just before the holiday season, as he entered his final month as President of the United States, Joe Biden announced that he would be granting clemency to roughly 1,500 American citizens. The clemency acts, which included sentence commutations for individuals placed on home confinement during the pandemic and pardons for 39 individuals with non-violent offenses, were touted by the administration as the most ever in a single day in modern history. A month later, on January 17, he commuted the sentences of roughly 2,500 individuals convicted of non-violent drug offenses, shattering December's mark and giving him the most pardons and commutations of any president in United States history. The unprecedented size of the actions has been underscored throughout The White House’s press materials and has headlined most subsequent news coverage. But for Anton Robinson, JD, associate professor of law and director of Villanova’s Caritas Clemency Clinic in the Charles Widger School of Law, the importance of the clemency went far beyond the impressive scale. “Acts like these bring much needed awareness to the clemency process, and to the epidemic of excessive sentencing in United States courtrooms,” Professor Robinson said. “At our clinic, we are already having people call to ask about opportunities for pardons and additional support for their cases.” Public perception of presidential acts of clemency can, at times, be marred by partisan divisiveness. To some, these latest acts were overshadowed by President Biden’s earlier pardon of his son, Hunter, and eyes are already on incoming President Trump regarding how he might handle those charged in relation to the January 6 insurrection. Professor Robinson acknowledges that acts like these can cause people to “rightfully question the power that is being used,” but those are the outliers, not the norms, and steer the conversation away from the root purpose of clemency. “People deserve a second chance,” Professor Robinson said. “There’s a tendency for system actors to focus primarily on the crime committed when considering whether a person’s sentence should be cut short. But many are different people today—sometimes decades later—than they were at the time of the crime’s commission. “There is also no shortage of individuals in prison for whom a charge doesn’t tell the whole story. For example, a young person’s involvement in a crime, while sufficient for a legal conviction, might be weighed differently today, given increasing acceptance of scientific research on the portion of the human brain which controls decision-making, impulse control and executive function. Research shows all of that continues to develop well into adulthood.” Determining who fits the criteria for clemency, Professor Robinson says, is not always easy to do. Collecting records of good behavior that illustrate change while in a carceral setting is much more difficult than collecting records of bad behavior. That’s why entities like the Caritas Clemency Clinic, in which Villanova Law students work directly on behalf of such clients under Professor Robinson’s guidance, spend so much time talking to anyone who has had a relationship with the incarcerated person. “What we often find is that despite being incarcerated and having very little given opportunity, these individuals make their own opportunities to build community and rich relationships and try their best to contribute to society in a positive way,” Professor Robinson said. A military veteran who helped church members in poor health perform tasks. A nurse who spearheaded COVID vaccination efforts and natural disaster response. A counselor who helps guide youth away from destructive behavior and involvement with gangs. Those are the types of actions Professor Robinson references, all of which were highlighted specifically in the White House’s fact sheet for President Biden's December acts, just before the words “The United States is a nation of second chances.” “I'm hoping that these large acts of clemency encourage folks to think, ‘Hey, what about my loved one? What about me? I am a completely different person than I was 20 years ago, what can I do to try to secure my freedom and my ability to live the life that I've missed out on?’” Professor Robinson said. “It really is a great opportunity to remind ourselves that people are far better than the worst things that they've ever done, and that we have an opportunity to acknowledge that as a society and to encourage more of this action, both on a federal and state level.”

Villanova Professor Investigates Impacts of Hurricanes on Florida Coast

In October 2024, during the height of hurricane season, Hurricanes Milton and Helene swept across the southeastern United States. Their impact on Florida was severe, with damages totaling tens of billions of dollars. While communities in affected states continue to rebuild, a team of researchers mobilized to assess the damage caused in the hopes of better understanding the impacts of hurricane activity in the future. Jonathan Hubler, PhD, assistant professor of civil and environmental engineering at Villanova University, along with Villanova civil engineering graduate student Sarah Burghardt, traveled to Florida with a joint team from the Nearshore Extreme Events Reconnaissance (NEER) Association and the Geotechnical Extreme Events Reconnaissance (GEER) Association to investigate the immediate aftereffects of Hurricanes Milton and Helene. The National Science Foundation-sponsored trip gathered natural hazards research experts and practitioners from across the country, who quickly jumped at the opportunity to examine the impacts of two tropical storms that occurred in quick succession of each other. A few main areas of study were identified by the team so they could hit the ground running once they touched down in Florida. The researchers wanted to focus primarily on the effects of storm surge, waves, sediment erosion and deposition, and debris transport and accumulation from both hurricanes through pre-storm, during-storm, and post-storm data collection. Over 750 miles were covered across just a few days as data was surveyed and collected from Cedar Key, Horseshoe Beach, Venice, Port Charlotte, Port St. Lucie, Vero Beach and other coastal towns. “This was a unique opportunity for our team of scientists because our team collected data before the storms so we will be able to analyze the direct impacts of the storms utilizing the post-storm data that we collected,” said Dr. Hubler. “Although the destruction was difficult to witness firsthand, we are hopeful that our findings will help to mitigate the impact of these major storms in the future.” The data set collected from these storm sites is expected to improve the understanding, prediction, and mitigation of erosion as well as assess the performance of different shoreline protection systems during severe tropical storm events. Findings from the trip will be shared publicly through the NSF’s Natural Hazards Engineering Research Infrastructure (NHERI) DesignSafe-CI, a nationwide network tailored for data sharing among the natural hazards engineering research community. Local Florida communities will also be notified of relevant findings to increase awareness and understanding of risk assessments when preparing for tropical storm events. “It was a productive few days spent in Florida as we collected a significant amount of data and covered a lot of ground in a short span of time. I’m grateful to have been included on this research team and that I had the chance to bring one of my students along. This real-world experience in the field will help further her learning as she completes her studies,” said Dr. Hubler. Dr. Hubler traveled with the NEER and GEER team again in November for another data collection effort. Although the 2024 hurricane season has come to a close, researchers like Dr. Hubler continue to study their impact year-round to discover new mitigation strategies for next year’s season.

Villanova Biologist Alyssa Stark Looks to the Natural World for Solutions as Field of Biomimicry Expands

Humans have long taken inspiration from the natural world. From the indigenous cultures of the world who understand and utilize the properties of plant and animal products, to Leonardo da Vinci’s “flying machine” sketches inspired by his observations of flying birds, humankind has often looked to nature to help solve its problems and drive innovation. With rapid scientific advancements of the 19th and 20th centuries, and the exponential growth of sustainability practices over the last quarter century, the concepts of bio-inspired design and biomimicry have been increasingly pursued across myriad disciplines of study and implementation. Alyssa Stark, PhD, associate professor of biology at Villanova University, is one of the “boots-on-the-ground” researchers in pursuit of nature’s solutions to human problems. She recently took the time to chat with us about these fields, her research interests and the future of biomimicry. Villanova PR: We sometimes hear the terms “bio-inspired design” and “biomimicry” used interchangeably. Are they the same concept? Alyssa Stark: I see those as two different things. Bio-inspired design is when we are looking at an organism and see that it’s doing something that we want to emulate as humans. I work with animals that have unique adhesive properties. I ask questions like: Can we see that? Can we build it? Can we transfer that information, those ideas, those principles – it could be chemistry, physics, biological structure – and make something useful for us? That is also true with biomimicry, but the big difference for me is that we're keeping in mind the sustainability components. The natural world is not polluting. If we're using this biomimicry lens, how do we learn from nature to make products or solve problems in a sustainable way, keeping in mind the specific environment in which we are located? As an example, we wouldn't use a heavy water process if we were in the Arizona desert, instead we should look to our immediate surroundings to solve problems. PR: It seems the work going on in this field really takes a unique level of interdisciplinary collaboration. What types of different professionals are working in biomimicry? AS: It really pulls together biologists, engineers, physicists, chemists, even design artists and businesspeople. I've worked with a lot of different businesses that want to have sustainability in their company at broad levels by using biomimicry. They are not motivated by making a cool product, but realizing it actually saves them money if they think about their whole company in a biomimetic perspective. There are people who work on the social side of biomimicry, helping these companies completely restructure themselves to be more efficient and more time and money sensitive, without ever making a product. But of course, products are a huge part of it, too. And to make that happen, all of those professions, and more, are vital and active in this space. PR: In terms of products, what are some of the most successful examples of biomimetic designs being implemented? AS: A classic one is a building in Africa that doesn't have any air conditioning units because it has a series of vents like a termite mound. Or the bullet train being shaped like a kingfisher’s beak. One scientist found that whales have bumps on their fins, which you might think is not hydrodynamic. But as it turns out, it actually cuts through water more efficiently by creating little vortices. This concept was then applied to wind turbines. There are many examples of biomimicry actually working and being used. My mind is blown when I talk to an artist or designer about biomimicry because it's just wild the way they think. PR: Where does your overall work as a biologist fit into the world of biomimicry? AS: My hard science work is very much functional morphology – shape and structure of things and how they function. That includes behavior and their organismal interaction with the environment. I ask questions like: How do their structures function and perform? How sticky are they? How fast are they? How do they behave in their environment? What happens if they hit different challenges in their environment? My work kind of naturally fits well with biomimicry, especially for product development. I observe the natural world and then I start testing questions and predictions that I have about it, like figuring out how the heck this ant is sticking to this wet leaf. My results can then be applied directly. We have to first understand how these organisms work, and then others can run with it to try to put it to use. PR: What organisms do you work with and what about them are you studying? AS: I mostly study geckos, ants, and sea urchins and I just started working with some coral, looking at why some coral undergo bleaching, and some don’t. With sea urchins, we're also figuring out where their incredibly hard teeth are mineralized so we can understand it enough to try to mimic it. I like playing in that zone, because it still provides me a chance to do the hard science, but also talk to engineers and others and provide them information. With geckos, what I kind of broke open with my PhD thesis was that they have an adhesive that works in wet environments. Having a reusable adhesive that can work on skin, especially in the medical world, is a big problem and where most of my research lies. Think of a bug that you can’t pry off, but then it suddenly runs. How do these organisms move with such sticky feet? Figuring out how to make a reusable adhesive that doesn’t get dirty and can handle all these different environments is a difficult problem to solve. PR: How do you see this field evolving, especially as we strive for a greener, more sustainable future? AS: I would say the next step is the social levels of these big ecosystems. How do we build a city that functions like a rainforest or like a coral reef? Not just a product, but how do we actually shape our world by taking behaviors, processes, or systems that we see in the natural world to help us? Look at a pride of lions and their hierarchy, or what kind of feedback loops are there in an ant colony that allow them to give information back to their colony members quickly and share resources. I think that is the future of this field, and it’s an exciting future. *To learn more about Dr. Stark’s research and the field of biomimicry, click here to listen to a recent episode of NPR’s science show, “The Pulse.”
