Key Takeaways

You did it. You started your weight loss journey! You’ve spoken to a healthcare provider and received a prescription for a GLP-1 medication like Wegovy (semaglutide) or Ozempic (semaglutide).

But you’ve been taking semaglutide for a while. You’re not losing weight. What gives?

You may not see the results you were hoping for for several reasons. This article will explore some of the most common reasons why Wegovy and Ozempic aren’t helping you lose weight, along with tips for speeding up your weight loss.

What are Wegovy and Ozempic?

Wegovy (semaglutide) is a prescription weight loss medication made by Novo Nordisk. It is FDA-approved for weight management in adults and children over 12 with overweight or obesity. Ozempic (semaglutide) is a prescription medication that’s FDA-approved for the treatment of type 2 diabetes, but it is prescribed off-label for weight management because it works the same way as Wegovy.

Semaglutide—the active ingredient in Wegovy and Ozempic—is a type of medication called a glucagon-like peptide-1 receptor agonist (GLP-1). It is a synthetic version of the natural hormone GLP-1, which works in part by regulating insulin release and slowing your stomach emptying to manage blood sugar and promote feelings of fullness.

Both Wegovy and Ozempic are prescribed alongside lifestyle changes like diet and exercise.

Why am I not losing weight on Wegovy or Ozempic?

You may not be hitting your weight loss goals while taking semaglutide injections for several reasons.

1. You need more time

Weight loss results take time! Keep in mind that the longer you take Wegovy or Ozempic, the more apparent your weight loss results will be.

For example, clinical trial participants taking 2.4 mg of semaglutide each week (the maximum allowed dosage for Wegovy) lost an average of 2% (about 5 lbs) of their body weight after 4 weeks of treatment. That number increased to 15% (around 35 lbs) after 68 weeks. Weight loss results may take even longer on Ozempic, which has a maximum allowed dosage of 2 mg of semaglutide per week.

In other words, results won’t happen overnight – that’s over a year of weekly semaglutide injections and healthy lifestyle changes.

Tip: If you’re frustrated by not losing weight, take stock of how long you’ve been using the medication. Many people don’t start seeing visible weight loss with Wegovy until the 20-week mark. Consider talking to your prescribing provider if it has been over 20 weeks. They can help determine whether a higher dose may help you reach your goal.

2. You need to eat a healthy, reduced-calorie diet

Wegovy and Ozempic are not prescribed alone. When providers prescribe semaglutide, they also advise healthy lifestyle changes like regular exercise and a healthy diet. If you have been struggling to lose weight while using Wegovy or Ozempic, ask yourself if you are maintaining these practices. Unhealthy eating habits like snacking between meals, overeating during meals, or eating a high-calorie diet may prevent you from getting where you want to go.

Tip: Talk to your provider about your dietary habits to see if there is anything you can adjust. They will likely recommend that you focus on eating nutritious food like vegetables, fruits, and whole grains while avoiding foods high in saturated fats or sugar. Your provider may also be able to suggest a sustainable meal plan and caloric intake recommendation to make sure you are getting the nutrition you need.

3. You need to get more exercise

Trials show that semaglutide is most effective for weight loss when patients get at least 150 minutes of moderate-intensity aerobic exercise each week. That’s equal to about 21 minutes a day or 30 minutes a day, 5 times per week. Aerobic exercise can be brisk walking, swimming, dancing, cycling, weight lifting, or jogging. Even yard work counts!

Getting at least 150 minutes of aerobic activity per week will also help reduce your risk of cardiovascular complications, like high blood pressure.

Tip: Ask a healthcare provider for some suggestions on starting your fitness routine. Jumping into high-impact, strenuous exercise leaves you at risk for burnout or injury. Work with your provider or a weight loss specialist to craft an exercise regimen that is appropriate for your needs and experience level.

4. Stress is hurting your progress

Did you know that high stress levels are associated with overweight and obesity? This is because stress encourages the release of cortisol, a natural hormone that plays a role in metabolism. It gives us a surge of energy but also encourages us to overeat or crave foods that aren’t as healthy.

Tip: Luckily, there are lots of steps you can take to relieve stress. Getting more physical activity can keep cortisol levels down, and so can stress-reduction techniques like deep breathing, yoga and meditation.

5. You need to get more sleep

In addition to managing your stress, it’s vital that you get enough sleep. Not getting enough sleep is linked to high cortisol levels and an increased risk of obesity. Aim for 7-8 hours of sleep per night.

Tip: Practice good sleep hygiene by turning in and waking up at the same time every day. Wind down before bed and avoid using your phone, laptop, or tablet right before trying to sleep. While these devices are a central part of nearly all of our lives, they can hurt the quality of your sleep.

Discuss your sleep and stress with your healthcare provider. Incorporating healthy sleep habits into your daily routine may help you start seeing the results you want.

6. You’re dealing with an underlying health condition

If you’re not losing weight on Wegovy or Ozempic, it might not be due to anything you are or aren’t doing. It may be that an underlying medical condition is to blame. Conditions like hypothyroidism can make it hard to lose weight.

Additionally, certain medications, like antipsychotics and some blood pressure medicines, may cause weight gain. They may also slow weight loss.

Tip: If you have been maintaining healthy habits while taking Wegovy or Ozempic and are not losing weight, talk to your provider. They may screen you for other health conditions. Before starting treatment with semaglutide, tell your provider about your medical history and any medicines you are taking. This will reduce your risk of harmful drug interaction side effects. It will also give your provider a fuller picture of your health and potential barriers to weight loss.

Are there alternatives to Wegovy and Ozempic?

Wegovy and Ozempic are not the only GLP-1 medications on the market. If you’re not seeing results, your healthcare provider may elect to increase your dosage. They may also prescribe a different medication instead.

Other GLP-1 or GLP-1/GIP medications that are FDA-approved for weight loss include Saxenda (liraglutide) and Zepbound (tirzepatide). Discuss these options with your provider, as well as possible drug interactions and side effects.

Should I talk to a doctor?

There are many reasons why you aren’t getting the results you want while taking a weight loss drug. The six detailed above are among the most common. They are also entirely fixable.

Remember that weight loss is a journey. If you’re frustrated by the process, talk to a healthcare provider. Ask about your treatment and what you can do to improve it. It may be that a simple lifestyle change will help speed up your weight loss on Wegovy or Ozempic. Or, you may have a medical condition that requires treatment before you can fully benefit from weight loss medication.
