The Reality of GLP-1 Drugs Seen from Social Media: "Over 20% Weight Loss" vs. "Almost No Change" with the Same Ozempic

Ozempic, Wegovy, Mounjaro, Zepbound.
In recent years, GLP-1 related drugs have gained global attention as "drugs that significantly reduce weight." On social media, testimonials about changing clothing sizes in a few months, quieted appetites, and experiencing a feeling of fullness for the first time in life are being posted one after another.

However, there are also completely different voices.

"Even though I'm using the same drug, I hardly lose any weight."
"My friend kept losing weight, but I stopped after losing a few kilos."
"My appetite decreased a bit, but I still eat out of stress."
"When I stopped, the weight started coming back."

The article featured on Yahoo Creators addresses this very "difference in effectiveness." GLP-1 drugs are not simple appetite suppressants that work the same for everyone. Genetics, brain reward systems, eating behavior, glucose metabolism, gut environment, muscle mass, and how the drug is taken and continued are all intertwined, altering the results.

In other words, what is truly being questioned in the era of GLP-1 drugs is not just "whether it works or not."
"Why does it work more easily for some people?"
"Why is it less effective for others?"
"In cases where it is less effective, what should be combined with it?"
These are perspectives of more personalized medicine.

Not a "Magic Injection," but a Drug with Significant Individual Differences in Response

GLP-1 is a type of hormone secreted after meals, involved in regulating blood sugar levels, appetite, gastric movement, and satiety. GLP-1 receptor agonists are drugs that utilize this mechanism to aid in blood sugar control and weight management.

However, even with the same drug, dosage, and duration, results can vary greatly. The original article, citing research from the 23andMe Research Institute, introduces that while some people lose over 20% of their body weight, others lose less than 5%, or even gain weight.

This difference cannot simply be attributed to "those who tried hard" and "those who didn't." Of course, food intake, exercise, sleep, and continued medication are important. However, as research progresses, it becomes apparent that how the body responds to GLP-1 signals, how the brain processes appetite and rewards, and the reasons for overeating can influence the drug's effectiveness.

The direct clash of posts on social media saying "it worked for me" and "it didn't work for me" is not because one side is wrong. It's because the response to the drug truly varies from person to person.

The Potential for Results to Vary Based on Overeating Type

Particularly intriguing in the original article is the perspective that "why one overeats" is related to the response to GLP-1 drugs.

Overeating can be broadly categorized into several types.
For example, "external eating behavior," where one is strongly attracted to appetizing things in front of them. This type responds to external stimuli like appearance, smell, store advertisements, and the dining scenes around them, increasing appetite.

On the other hand, there's "emotional eating," where one eats to alleviate stress, anxiety, depression, loneliness, or anger. This is more about eating to calm emotions rather than eating due to hunger.

Research from Kyoto University and others suggests that the effect of GLP-1 receptor agonists may vary based on these types of eating behaviors. Those who eat in response to external stimuli tend to experience more weight loss, while those with strong emotional eating tendencies show weaker weight loss.

This is an important point. While GLP-1 drugs act on appetite and satiety, they are not drugs that fundamentally resolve stress or anxiety. For those with strong emotional eating patterns, it becomes important to combine the drug with cognitive behavioral therapy, stress management, sleep improvement, and psychiatric or psychosomatic support as needed.

This point is repeatedly discussed on social media. On Reddit, there are posts with sentiments like "the feeling of wanting to eat out of boredom or anxiety remains even though hunger has decreased," and discussions like "appetite suppression alone doesn't change lifestyle habits." While GLP-1 drugs may weaken the impulse to eat, they do not automatically resolve the psychological background of relying on food.

Can Genetic Testing Determine "Effectiveness"?

Another focus is genetics.

Research from Stanford Medicine and ETH Zurich reports that individuals with genetic variations related to GLP-1 function may have a weaker response to GLP-1 drugs. The original article mentions the possibility that about 10% of people have such variations, and introduces the expectation that in the future, genetic testing might predict the likelihood of effectiveness before treatment.

However, at present, it is not at a stage where one can say, "If you take this test, you'll know if Ozempic will work for you." While important as research, it is not yet a mature predictive tool for everyday clinical use.

For now, the more practical indicator is considered to be "how much one responds in the first few months." Those who start losing weight early tend to continue to see significant decreases. Conversely, if there is little response after about three months, it may be necessary to review the dosage, type of drug, diet, medication method, complications, and psychological factors.

This is an important perspective for patients as well.
Before blaming oneself for having a "weak will," it's better to check the response with a doctor and adjust the treatment plan. GLP-1 drugs should be viewed as medications that are optimized while monitoring progress, not as "once it fits, it's over" drugs.

Weight Loss Also Varies Depending on the Presence of Type 2 Diabetes

GLP-1 drugs have been widely used as treatments for type 2 diabetes. Even now, as they are increasingly discussed in the context of weight management, their relationship with glucose metabolism cannot be separated.

The original article explains that individuals with type 2 diabetes tend to experience slightly less weight loss compared to those without diabetes. This is thought to be influenced by multiple factors such as insulin resistance, blood sugar control, concomitant medications, basal metabolism, and medical history.

On social media, there are posts from people using Ozempic for the treatment of type 2 diabetes saying, "It was effective for blood sugar, but the weight didn't decrease as much as expected." Conversely, posts from those using it for weight management often highlight experiences like "suddenly lost appetite" and "reduced obsession with food."

It's important to note that weight loss is not the only value of the drug. For diabetes patients, blood sugar levels, cardiovascular risk, and kidney impact are also important treatment goals. While "how many kilos lost" tends to attract attention on social media, medically, the success of the drug cannot be judged by that alone.

Gut Environment is Related, but "Improving Gut Health Before Starting" is Not Yet Proven

Research on the relationship between GLP-1 drugs and gut bacteria is also progressing. While the composition of gut bacteria may affect the drug's effectiveness, GLP-1 drugs themselves may also change the gut environment.

However, as pointed out in the original article, there is currently insufficient evidence to definitively say, "Improving gut health before starting the drug enhances weight loss effects." While there is high interest in yogurt, fermented foods, dietary fiber, and probiotics, it is not yet at a stage where using them can reliably improve the response to GLP-1 drugs.

Of course, a balanced diet including dietary fiber is important for overall health. During the use of GLP-1 drugs, which can easily cause constipation, stomach discomfort, and decreased food intake, adjusting the diet is also essential. However, simplifying it to "improving gut health makes the drug effective" would be an exaggeration beyond current science.

The Issue of Losing "Muscle" Along with Weight

Recently, concerns about "losing muscle" have been increasing in social media reactions regarding GLP-1 drugs.

When weight is lost, it's not just fat that's reduced. Lean body mass, including muscle, also decreases to some extent. The original article explains that about one-third of the reduced weight could be components other than fat. Special attention is needed for the elderly, males, and those who lose weight rapidly.

Researchers from UVA also point out that weight loss due to GLP-1 drugs does not necessarily lead to improvements in cardiorespiratory function, and separate measures are needed to maintain muscle mass and physical strength.

Here, protein intake and resistance training become important.
Simply reducing the numbers on the scale might be achievable by reducing food intake. However, for long-term health, it's important to reduce fat while maintaining as much muscle as possible.

On social media, there are voices saying, "I lost weight but feel like my physical strength has decreased," "I can't eat enough protein," and "My appearance stabilized after starting strength training." While GLP-1 drugs can be a powerful aid in weight loss, they are not a substitute for building a healthy body.

Possibility of Affecting Not Just "Appetite" but Also "Reward"

Particularly striking in the testimonials about GLP-1 drugs is the voice that desires beyond food have also weakened. Posts about reduced alcohol consumption, calmed shopping impulses, and diminished interest in smoking are common on overseas social media.

This suggests that GLP-1 drugs may not only act on the gastrointestinal system to enhance satiety but also affect the brain's reward system. The original article introduces the view that GLP-1 drugs do not erase "pleasure itself" but rather weaken the "desire" to pursue rewards.

This perspective significantly changes the image of GLP-1 drugs.
They may not just be "drugs that suppress appetite," but rather drugs that adjust the motivation towards food and indulgences.

However, caution is needed here as well. Application in addiction treatment or mental symptoms is still under research, and it should not be used based on self-judgment. While social media testimonials provide valuable hints, they should be treated separately from medical conclusions.

Which is Better: Oral Medication or Injection?

The original article also touches on the oral Wegovy expected to debut in 2026. If the option to use it as an oral medication rather than an injection becomes available, it would be a significant change for those who are resistant to injections.

However, oral medications come with the difficulty of how they are taken. Oral semaglutide needs to be taken on an empty stomach in a prescribed manner, and timing with meals and other medications can affect the results. While injections are needed only once a week, oral medications require daily habituation.

On social media, there is anticipation from those afraid of injections saying, "If it's oral medication, it's easier to try," while others express concerns like "I'm not confident I can stick to the daily rules" and "In the end, injections might be more reliable." Again, rather than one being absolutely superior, a choice needs to be made based on the individual's lifestyle rhythm, medication habits, cost, and doctor's judgment.

Will It Return After Stopping?—The Most Urgent Theme on Social Media

The most urgent response regarding GLP-1 drugs on social media is "what happens after stopping."

On platforms like Reddit, there are many posts saying, "Appetite returned after stopping the drug," "Weight started coming back," and "I'm worried about using it for life." The original article also treats weight regain after stopping GLP-1 drugs as a well-known issue.

This is related to the view of obesity as a chronic and recurrent disease rather than a temporary lifestyle disruption. Just as blood pressure can return after stopping hypertension medication, some people experience a return of appetite and weight after stopping GLP-1 drugs.

However, not everyone returns in the same way. Those who have managed to adjust their eating patterns, exercise habits, sleep, and stress management while using the drug may find it easier to maintain. Conversely, if food intake decreases only due to the drug and lifestyle habits remain unchanged upon stopping, rebound is more likely.

Discussions on social media tend to polarize on this point.
Criticisms like "It's strange to rely on drugs for life" are countered with arguments like "Continuous treatment is natural for chronic diseases." Rather than deciding on one side, it's necessary to consider the individual's medical history, complications, cost, side effects, and quality of life, and plan long-term with a doctor.

Social Media Reactions Divide into "Praise," "Anxiety," and "Backlash"

Reactions on social media regarding GLP-1 drugs can be broadly divided into three categories.

The first is positive testimonials.
"I understood the feeling of fullness for the first time."
"I stopped thinking about food all day."
"My blood sugar levels improved."
"I found room to start exercising."
In these posts, GLP-1 drugs are described not just as weight loss drugs but as a means of liberation from long-standing issues with appetite and metabolism.

The second is anxiety and confusion.
"Not losing as much weight as expected."
"The side effects are tough."
"Worried about losing muscle."
"Will it come back after stopping?"
"Can't afford the cost."
This group struggles with the gap between high expectations for the drug and reality.

The third is social backlash.
"Losing weight with drugs is cheating."
"Cosmetic use might prevent those who really need it from getting it."
"Obesity should not be treated as personal responsibility."
These discussions indicate that GLP-1 drugs are tied not only to medicine but also to issues of appearance, class, insurance systems, drug pricing, and prejudice.

The word "cheating" is particularly deep-rooted. On social media, there are posts viewing those who lost weight with drugs as if they didn't make an effort. However, obesity and type 2 diabetes are not simple matters of willpower. Appetite, hormones, genetics, environment, stress, sleep, and economic conditions are intertwined. Using drugs can be seen as one of the medical practices to supplement the body's characteristics, just like wearing glasses or taking blood pressure medication.
