Weight Loss Drugs Like Wegovy & Ozempic Can Influence Taste Sensitivity

Did you know that popular weight loss medications like Ozempic and Wegovy might be changing the way you taste sweets? Recent research led by Mojca Jensterle Sever, PhD, Slovenia, from the University Medical Centre in Ljubljana, has uncovered some fascinating insights. Presented on June 1 at the ENDO 2024 conference in Boston, the study shows that semaglutide, the active ingredient in these drugs, affects our taste sensitivity and the brain’s response to sweet flavors. They even noticed changes in how taste-related genes behave in our tongues. Let’s dive deeper into what this means for those using these medications.

What Is Semaglutide?

Now, let’s explore how semaglutide works. You might know this drug better as Ozempic, a name that’s become quite familiar in the health community. Originally it was developed to treat type 2 diabetes, it helps lower blood sugar levels effectively. But that’s not all it does.

Semaglutide also plays a key role in managing appetite and slowing down digestion. This means you end up eating less and gradually losing weight—a welcome benefit for many struggling with obesity, a condition that hasn’t had many breakthrough treatments until now.

Healthline caught up with Mir Ali, MD, a board-certified bariatric surgeon and medical director at MemorialCare Surgical Weight Loss Center in California, to get a clearer picture. Dr. Ali highlighted why semaglutide is a game-changer. “These drugs are more effective than previous medications available,” he shared. “They directly target hormones that make patients feel less hungry and more satisfied after meals, which helps them maintain a lower calorie intake for longer.”

What Is the Role of Taste Sensitivity In Obesity?

We all have a natural inclination to enjoy foods that are rich in sugar & fat, substances essential for life. When we indulge in these foods, our brains reward us with a burst of pleasure. However, in modern Western societies, access to these tempting foods is far easier than it was millennia ago, creating a mismatch between our evolutionary preferences and the abundance of highly appealing, easy-to-access treats today. Just a swipe on a phone can lead us to a multitude of these delicious, high-calorie options.

As we consume more of these foods, our sensitivity to them can diminish, a phenomenon linked to increased obesity risk. Research indicates that individuals with obesity may not only be less sensitive to sweet tastes but also more drawn to them. Animal studies further suggest that GLP-1 signaling, a critical biological pathway, is involved in managing how we perceive tastes, particularly sweet ones. This insight has led researchers to speculate that changes in taste sensitivity could also contribute to the effectiveness of weight-loss drugs like semaglutide.

While it’s known that semaglutide mimics hormones that signal fullness to the brain, reducing appetite and promoting weight loss, there might be more to the story. 

How GLP-1 Drugs Can Affect Your Tastebuds?

In a fascinating study led by Mojca Jensterle Sever, a team investigated how GLP-1 drugs like semaglutide impact taste perception. The study involved 30 women with obesity, around 34 years old on average. Half received semaglutide weekly, while the others were given a placebo.

Over 16 weeks, the researchers assessed:

  • Taste Sensitivity: Using taste strips infused with the four primary tastes—sweet, sour, salty, and bitter.
  • Gene Expression: Through tongue biopsies to study changes at the cellular level.
  • Brain Responses: By conducting functional MRI scans, participants tasted a sweet solution, both before and after eating.

The results were intriguing. Those on semaglutide showed heightened taste sensitivity compared to the placebo group. The tongue biopsies revealed that genes involved in taste signaling, neural plasticity, and the renewal of taste buds were more active.

Moreover, the brain scans highlighted increased activity in the angular gyrus—a part of the parietal cortex. This area integrates sensory information and is critical in processing the significance of events or stimuli. It contains GLP-1 receptors and is associated with shifting attention between rewarding and neutral stimuli. The heightened activity here suggests a possible shift in how rewards from sweet tastes are perceived, potentially aiding individuals in making healthier dietary choices and progressing towards a healthier weight.

It’s important to note that this was a proof-of-concept study with a limited number of participants, conducted in a controlled lab environment. As Dr. Sever points out, “the results may not reflect everyday experiences, and the variability in taste perception among individuals could limit the broader application of our findings.” Nonetheless, this study opens up intriguing possibilities about the role of GLP-1 drugs in managing obesity through changes in taste sensitivity.

Who Should Take Semaglutide?

While the buzz around semaglutide, particularly for weight loss, is growing, it’s not a one-size-fits-all solution. Healthline recently discussed this with Federica Amati, PhD, a leading nutritionist at ZOE, who emphasized the selectiveness in recommending this treatment.

“Semaglutide can be remarkably effective for some, but it comes with its set of challenges,” Amati notes. She advises that semaglutide should only be used when prescribed by a healthcare provider who is part of a comprehensive care team. This team should include support for mental health, physical activity, and, importantly, dietary guidance to ensure a balanced intake of nutrients—crucial because semaglutide typically reduces appetite.

Amati also highlighted a key aspect of Ozempic dosing for weight loss: “It’s essentially a lifelong commitment. Those who stop taking it often regain the weight they lost, so it’s far from being a quick fix.” Moreover, she pointed out that while many people tolerate the drug well, about a third experience side effects that, although not severe, can be quite bothersome. Semaglutide holds promise for those struggling with obesity, but it requires careful consideration and a holistic treatment approach to be indeed effective.


As we’ve seen, semaglutide, commonly known under the brand names Ozempic and Wegovy, offers promising benefits for those struggling with obesity. This medication not only reduces appetite and influences how our bodies process food, but it also alters our taste sensitivities, potentially helping users make healthier dietary choices. However, it’s important to remember that semaglutide is not a quick fix. 
It requires a long-term commitment and should be part of a comprehensive treatment plan that includes dietary advice, physical activity, and mental health support. If you’re considering this treatment, it’s crucial to consult with your primary caregiver to understand if it’s suitable for you. For those looking to access this medication, one can buy Ozempic from Canada, where it may be available at more competitive prices. As always, ensuring that you have the right support and information is vital to making an informed decision about your health.
