How much weight can you lose on Ozempic?

Since Ozempic (semaglutide) became a popular off-label option for people trying to lose weight, there have been dramatic reports from patients about their impressive weight loss while using the medication and others like it. But just how much weight can you lose on Ozempic, actually? 

Before answering that question and going into the average weight loss on Ozempic, it’s important to note that the drug is not actually indicated for weight loss. Rather, Ozempic is approved by the US Food and Drug Administration (FDA) to control blood sugar in people who have type 2 diabetes and to reduce the risk of major cardiovascular events (e.g. heart attack, stroke) or worsening kidney disease in those with type 2 diabetes and heart disease or chronic kidney disease. Still, however, the drug can be (and often is) prescribed off-label for weight loss. That’s largely thanks to its appetite-suppressing and slowed gastric emptying effects. 

So, back to the matter at hand: How much weight can you lose on Ozempic? Ahead, we answer that question by reviewing the average weight loss on Ozempic, according to research. We also share tips on how to maximize weight loss on Ozempic depending on your goals. 

In clinical trials of Ozempic, which is one brand-name version of the drug semaglutide, 37%–66% of people lost at least 5% of their body weight, and 13%–26% of people lost at least 10% of their body weight while taking the medication. Meanwhile, another study found that people lost an average of 13–15 pounds in the first 10 months of taking the drug. Although these findings are impressive, how much weight you can lose on Ozempic is different for everyone. 

Factors that affect how much weight you can lose on Ozempic include whether or not you have type 2 diabetes, the dose, your weight upon starting the drug, and whether or not you implement lifestyle modifications (e.g. diet, exercise).

People who have type 2 diabetes, for example, tend to lose less weight when treated with semaglutide than people without the condition. Also, the amount of weight a person loses while using Ozempic tends to be dose-dependent. In other words, in clinical trials, people taking lower doses lost less weight than participants taking increasingly higher doses. Typically, when starting Ozempic and similar medications, healthcare providers will have patients begin on lower doses and slowly titrate up to minimize side effects from the drug.

All in all, Ozempic and other semaglutide medications produce significantly more weight loss than diet and exercise alone. In one study comparing semaglutide to a placebo, those who took the placebo lost less than 4% of their body weight during a period of 68 weeks, while those taking semaglutide lost almost 10%. 

Whether you are taking Ozempic to manage type 2 diabetes, weight, or both, it’s important to remember that the medication is most effective when combined with lifestyle changes, such as diet and exercise.

Ozempic starts working as soon as you start taking the medication. For some people, that means they start seeing results fairly quickly. Studies show that people tend to start eating less during the day, experience fewer cravings, and lose an average of 11 pounds, all within the first three months of taking Ozempic.

How much weight can you lose in a month on Ozempic? 

“In the primary study of semaglutide for obesity, people lost weight as early as four weeks, about an average of 2% or 4.4 pounds,” says Beverly Tchang, MD, DABOM, Ro Obesity Medicine Advisor and assistant professor of Clinical Medicine at Weill Cornell Medicine in New York. “However, the first four weeks uses the lowest starting dose of semaglutide, 0.25 mg, which does not induce significant weight loss in many people. So, if you don't see weight loss in the first four weeks, that can be normal too.”

Translation: It’s difficult to determine how much weight you can lose in a month on Ozempic. That being said, we can consider additional findings, such as those from a 2022 clinical trial, and do some math. In this trial, 175 individuals with overweight or obesity received a weekly dose of 1.7 mg or 2.4 mg of semaglutide (the active ingredient in Ozempic). The mean baseline weight (i.e. participants’ average starting weight) was 118.1 kg or 260.4 pounds. After three months, participants had lost an average of 5.9% of their body weight, which in this study represented around 14 pounds. By rough approximations, this breaks down to about 5 pounds per month, though it’s possible some people lost more weight near the beginning of the period and other people near the end.

And that, dear readers, is around the same monthly average weight loss on Ozempic that Dr. Tchang mentions above. So, while there’s no universal answer and everyone’s experience is different, it’s likely safe to assume that you can lose around 4–5 pounds in a month on Ozempic, according to research. 

Ozempic is a glucagon-like peptide-1 (GLP-1) receptor agonist, a type of medication that mimics the GLP-1 hormone naturally found in the gut. Meaning, it binds to GLP-1 receptors and encourages the pancreas to release more insulin after you eat, which helps lower and stabilize blood sugar levels. Ozempic also positively impacts blood sugar levels by inhibiting the production of glucagon (a hormone that makes you feel hungry). 

Although these effects make Ozempic an effective medication for type 2 diabetes, stabilizing blood sugar isn’t all the drug can do. As a GLP-1, Ozempic slows gastric emptying, so it takes longer for food to leave the stomach and enter the small intestine. Because of this effect, people taking the medication may feel full sooner and stop eating, which can contribute to weight loss. There’s also evidence that Ozempic and other GLP-1 agonists like it have an effect on the parts of your brain involved in regulating your appetite, suppressing appetite and increasing satiety (fullness). 

There are several things people can do to maximize weight loss on Ozempic, from adapting certain lifestyle changes to addressing underlying health issues.

1. Change what you eat

As is the case for achieving weight loss goals sans medication, your diet can play an important role in how much weight you can lose on Ozempic. And while nothing is “off limits,” there are certain foods and drinks you might want to limit to help reduce digestive side effects and promote weight loss. 

Fried, greasy foods, for example, can cause gastrointestinal upset on their own. Add into the mix Ozempic, whose side effects are largely stomach-related, and you may increase your odds of experiencing nausea, bloating, and gas. These foods also tend to be high in calories and trans fats, with research linking fried food intake to obesity. 

Sugary foods and beverages, such as soda and candy, can lead to overeating and weight gain, according to research. They can also pose additional problems for those working to manage type 2 diabetes, as sugar quickly spikes blood sugar levels, and these spikes can have negative impacts on insulin sensitivity. This can counteract the potential effects of Ozempic.   

When you’re aiming for certain weight loss goals, consuming fewer calories—while keeping up with regular physical activity—can help you achieve or maintain a healthy weight. So, consider limiting foods high in empty calories but low nutrition (think: salty, sugary, fatty, and processed items) and eating fiber-full and protein-rich foods that increase satiety (e.g. fish, nuts, seeds, fruits, veggies) instead. 

Doing this can be easier said than done (hey, we get it). So, if you’re having difficulty getting enough protein, for example, Dr. Tchang says replacing one of your meals with a protein shake could be a good option. Not only do they pack in a ton of the macronutrient (which boosts feelings of fullness), but they’re also portion-controlled, so you know you’re getting the optimal amount of calories needed. Try to make sure your protein shake doesn’t pack large amounts of added sugar that might interfere with your diet.

2. Change how you eat

Ozempic works best when combined with diet and exercise. Now that we’ve covered how eating less can help maximize weight loss on Ozempic, let’s talk about how eating better can help too. 

For example, research shows that engaging in mindful eating can help you become more in tune with your body’s hunger cues, so you only eat when you’re actually hungry vs. out of habit or stress. Mindful eating is pretty straightforward. You can start by eating without distractions (i.e. not at your desk or in front of the TV) and focusing on how the food tastes and feels in your mouth.

Ozempic in combination with a healthcare provider, dietitian, or nutritionist’s advice can be another great way to maximize your weight loss efforts, adds Dr. Tchang. “In one clinical trial of Ozempic, about 1 in 3 people achieved at least 20% weight loss (or about 37 pounds on average) with a combination of meal replacement protein shakes, a low-calorie diet (1,200-1,800 calories/day depending on your body’s needs), physical activity (slowly ramped up to 200 minutes per week), and multiple visits with a dietitian-nutritionist.” 

Through Ro’s Body membership, for example, you can receive access to ongoing care and support that helps you navigate your weight loss journey and get the most out of your treatment. 

3. Add in exercise

Maintaining a regular workout routine is an essential component of achieving any weight loss-related goals. And that’s true when you’re taking Ozempic. 

As Dr. Tchang notes earlier, at least 200 minutes of physical activity per week is key to prevent weight gain and maintain weight loss on Ozempic. Not yet able to do 200 minutes per week? No problem. Try to do whatever amount of exercise that you can stick with and grow your habit from there. 

That being said, certain types of exercise can be especially beneficial if you’re taking Ozempic. Resistance training, for example, can not only help you build and maintain muscle—which is key for weight loss—but it can also help improve blood sugar over time—a pro for those taking Ozempic for diabetes. Meanwhile, a combination of cardio and strength training can also supercharge your ability to burn fat, build muscle, and, in turn, lose weight. (Keep in mind: the more muscle you have, the more energy or calories your body can burn during the day.)

4. Stress less, sleep more

Another example of easier said than done, right? But taking care of your mental health and prioritizing sleep really does matter, especially when it comes to weight loss. 

When you’re feeling stressed, you’re more likely to turn to high-fat, high-sugar, and high-calorie foods. Stress also makes it tougher to sleep and can even mess with hormone production—including the hormones involved in regulating your appetite.

Poor sleep, whether you’re not getting enough sleep or the sleep you get is characterized more by tossing and turning all night, is also linked to weight gain. People who are sleep-deprived tend to turn to the same high-calorie, low-nutrition foods that stressed-out folks do. They’re also more likely to snack. Meanwhile, people who get better sleep tend to lose more weight.

So, if you’ve been feeling stressed or exhausted (or maybe a bit of both), consider what steps you can take to sleep better and relax. Make sure you have room to get at least 7–9 hours of sleep per night and prepare for rest with a relaxing bedtime routine. Mindfulness-based exercises, including meditation, yoga, and deep breathing, can ease stress. And if things start to feel like too much, consider reaching out to a therapist for help.

5. Manage other health conditions

If you have other health conditions that might be slowing down your weight loss efforts—such as chronic pain or polycystic ovary syndrome (PCOS)—treating them can make things easier. 

For example, if you’re taking Ozempic for type 2 diabetes, Dr. Tchang recommends checking in with your healthcare provider about your treatment plan. “Be sure to speak to your doctor about other medications you are taking for diabetes since some can cause weight gain, like sulfonylureas and insulin,” she says. “Optimizing your medication regimen to avoid weight-promoting medications while still keeping diabetes under control is key.” 

Like any prescription medication, Ozempic can cause side effects. The most common side effects of Ozempic are gastrointestinal in nature and include:

• Nausea

• Vomiting

• Diarrhea

• Abdominal pain

• Constipation

Serious side effects can also occur on Ozempic, although they’re more rare. These include:

• Acute pancreatitis

• Diabetic retinopathy (a complication of diabetes that causes vision changes)

• Hypoglycemia (low blood sugar)

• Severe gastrointestinal reactions

• Serious allergic reactions

• Gallbladder or kidney problems

• Pulmonary aspiration during general anesthesia or deep sedation

Some people may be more at risk of experiencing serious side effects when taking Ozempic, including people who take insulin or who have a history of gastroparesis or diabetic retinopathy. Share your full medical history and a list of all current medications with all of your healthcare providers prior to starting Ozempic. Starting Ozempic may mean you need to take lower doses of medications that lower your blood sugar to avoid hypoglycemia.
