Key Takeaways:
- Ozempic and Wogovy are FDA-approved therapeutic options that contain the active ingredient Semaglutide.
- Although both drugs are associated with weight loss, in some individuals, there may be a stabilization phase, when further weight loss becomes slower or stagnates despite continued therapy.
- The effects of these drugs are not only influenced by therapy. Factors such as diet, level of physical activity, concurrent use of other medications, and psychological stress can significantly affect overall weight-loss outcomes.
Ozempic and Wegovy belong to a class of drugs known as GLP-1 agonists (glucagon-like peptide-1), which are indicated for the treatment of Type 2 Diabetes and other medical conditions. Both treatment options contain Semaglutide, a substance that can contribute to weight loss.
Weight loss with these drugs usually does not last indefinitely, even when you follow the recommended dose and protocol. At some point, it stagnates. This article explains why weight loss may stagnate while using GLP-1 agonists and what steps patients and doctors can take.
How Do Medications Like Wegovy and Ozempic Work for Weight Loss
Ozempic and Wegovy are therapeutic bases containing Semaglutide. This injectable drug belongs to the group of GLP-1 agonists (glucagon-like peptide-1 receptor agonists). These drugs act similarly to the natural GLP-1 hormone produced by the body after a meal. GLP-1 prompts the pancreas to release insulin while preventing the liver from storing sugar.
In addition, it slows digestion, affects the brain center responsible for appetite control, and regulates hormones that control the feeling of hunger, all of which can contribute to weight loss.
Together, these effects help you feel full longer after a meal and keep blood sugar levels stable. In this way, the total daily energy intake is affected, making it easier to achieve and maintain a healthy body weight.
Studies to date have shown that people using Ozempic lost an average of 6-7% of their body weight, while those using Wegovy lost approximately 15%.
Reasons You May Not Lose Weight on Ozempic
Both Wegovy and Ozempic can cause weight loss, but not everyone experiences the same results. Weight loss associated with Semaglutide may slow or stop over time, leading to a plateau during therapy.
Some patients notice rapid weight loss immediately after starting Ozempic or Wegovy, while others may experience a plateau without significant weight loss. These differences are often due to factors that affect how the drug works in the body. The following examples explain the key reasons why the effects of this therapy may vary.
How Much You’re Taking (Dose)
The doses of Ozempic and Wegovy can significantly affect the therapeutic effect. Scientific studies show that patients using higher doses of Semaglutide often experience greater weight loss.
Therefore, it is crucial to adjust the dose individually under a doctor’s or pharmacist’s supervision. However, higher doses also increase the risk of side effects. Users who receive higher doses of Ozempic or Wegovy may experience side effects more often, including:
- Nausea and vomiting
- Diarrhea
- Fatigue
- Constipation
- Heartburn(acid reflux)
- Headache
Your Dosing Schedule and Timing
Changes in weight after starting Ozempic or Wegovy are often not visible immediately but only after several weeks. Most users start with a lower dose, which is gradually increased to the target dose within three months. This procedure can help reduce the risk of side effects and facilitate continued therapy.
Even at lower initial doses, many patients notice decreased appetite, changes in eating patterns, and food cravings. However, the full effect on body weight is usually only seen when the target dose is reached.
Sticking to your medication schedule can also be crucial. Skipping or delaying doses reduces the drug’s level in the body, which can reduce its effectiveness. Using an alarm or calendar reminder can help you take your medication consistently, whether you’re still building up or at your target level.
If you Follow a Healthy Diet and Exercise

Semaglutide works best when used as part of a broader approach that includes a healthy, balanced diet and regular, moderate physical activity. The therapy itself can reduce appetite and food intake, but the way of eating still plays a crucial role in the final result. During the administration of drugs such as Ozempic or Wegovy, no food or drinks can reduce the effectiveness of therapy or increase side effects, especially those related to the digestive system.
It is recommended to limit or avoid:
- Fried food
- Food rich in fat
- Sweetened and carbonated drinks
- Ultra-processed products
- Alcohol
These foods can make it difficult to achieve therapeutic results, slow progress, and increase the likelihood of side effects such as nausea, bloating, or other gastrointestinal complaints. On the other hand, a balanced diet with sufficient protein, fiber, and fluid intake can improve tolerance to therapy and promote a more stable reduction in body weight.
Your Other Health Conditions
Semaglutide therapy does not work in isolation – its effect can be affected by other drugs you are taking due to associated diseases. In some situations, the presence of additional therapies may slow or complicate the expected results when using Ozempic or Wegovy.
Special care should be taken if you use:
- Sulfonylureas (glipizide or glyburide), which are used in the treatment of diabetes mellitus
- Antidepressants, such as mirtazapine or paroxetine
- Antipsychotics, including olanzapine or risperidone
- Corticosteroids, such as prednisone
These drugs can affect appetite regulation, blood sugar levels, fluid retention, or metabolic processes, making weight loss significantly more difficult. That is why it is crucial to consider the complete therapy as a whole, in agreement with the doctor.
What is the ‘Ozempic Plateau’?
The term “Ozempic plateau” refers to the period during GLP-1 therapy when weight loss slows or stalls, despite continued treatment. This kind of stagnation usually occurs after about a year from the start of Semaglutide therapy, when the body reaches a new balance and adapts to the therapy.
This phase can be influenced by numerous factors – from changes in metabolism and hormonal regulation, through the way of eating and the level of physical activity, to the simultaneous use of other drugs. Also, it is crucial to emphasize that the weight-loss process is tailored to each individual. Some patients experience a continuous decline in body weight, while others experience a period of stagnation before making further progress. Differences in response to GLP-1 agonists are expected and reflect the therapeutic effect’s availability.
What to do for Ozempic plateau
If there has been stagnation in the mix, and the goal is further progress, it is essential to consult your doctor to evaluate your current therapy and consider additional options. A period of downtime does not necessarily mean that the therapy is not working, but it may indicate the need to adjust the approach.
Depending on the individual assessment, the following measures may be recommended:
- Revision and more precise structuring of the diet plan
- Introducing a different type of physical activity or increasing the intensity and frequency of exercise
- Consideration of switching to another GLP-1 agonist, if clinically warranted.
Adjusting the therapeutic approach often helps to overcome the stagnation phase and facilitate further progress towards the set goals.
Average Weight Loss on Ozempic
Each patient using Ozempic may respond differently, as individual factors such as metabolism, lifestyle, and accompanying conditions play significant roles. Nevertheless, clinical research shows that most patients achieve a significant weight reduction during the first year of use.
In one study, patients who used Semaglutide for weight reduction lost an average of 15% of their initial body weight after 1 year of therapy. A longer-term study showed an average weight loss of approximately 10% during an extended period of Semaglutide administration.
These results indicate that therapy can have a significant effect, but the intensity and speed of the changes achieved vary.
What Happens When You Stop Taking Ozempic or Wegovy?
Weight loss achieved with Ozempic or Wegovy is not permanent if therapy is stopped. After stopping the drug, the body usually gradually regains some of the weight lost. Studies show that many patients regain some of their weight within a year of stopping therapy.
However, it is not common to regain all the weight. One study found that about half of participants maintained some weight loss a year after stopping Semaglutide.
These facts explain the importance of long-term adjustment of diet and lifestyle habits, because such changes can help preserve the results even when the drug is no longer in use.
Frequently Asked Questions
What to Pair with Ozempic for Weight Loss?
There is no “best” diet for weight loss with Ozempic. However, it is generally recommended to reduce the intake of foods rich in added sugar and fat, as well as to limit ultra-processed products and alcohol.
A varied, nutritionally rich diet can improve the outcomes of therapy and facilitate achieving and maintaining the desired body weight.
Is Wegovy better than Ozempic?
Wegovy and Ozempic contain the same active substance, Semaglutide, but are used for different indications. Therefore, it cannot be said that one drug is “better than another. The best option for you depends on your individual health goals, existing conditions, and medical history. A doctor’s advice can help you choose the therapy that is safest and most effective for your situation.
What is Stronger than Ozempic for Weight Loss?
Tirzepatide, the active ingredient in Mounjaro and Zepbound, can potentially cause more weight loss than Ozempic and Wegovy. However, additional clinical research is necessary to reliably confirm this claim.
The Bottom Line
Wegovy and Ozempic are glucagon-like peptide-1 (GLP-1) agonists. These drugs help treat various health conditions and, at the same time, lead to weight loss. In some patients, weight loss can be significant, while others notice only mild changes.
If GLP-1 therapy is not yielding results, it is essential to consult your doctor. It may be necessary to adjust the dose or give the current dose more time to work. The best effects of Ozempic and Wegovy are achieved when these drugs are combined with a nutritionally rich diet that limits intake of ultra-processed foods, fried foods, sugary drinks, and alcohol.
