How much weight can you lose on Ozempic?

How much weight can you lose on Ozempic (semaglutide)? It varies, depending on your starting body weight, your dosage, and whether or not you have type 2 diabetes. In clinical studies of Ozempic, people with type 2 diabetes have lost 13–15 pounds in ten months. Ozempic doesn't have its own weight-loss trial data in people without diabetes, but in early trials of semaglutide at a different dose and formulation, people without diabetes lost roughly 16–24 pounds in one year.

In clinical trials of Ozempic in people with type 2 diabetes, 37%–66% of people lost at least 5% of their body weight, depending on their dose.  Meanwhile, another study found that people lost an average of 13–15 pounds in the first 10 months of taking the medication.

Although these findings are impressive, how much weight you lose on Ozempic is different for everyone. Weight loss can vary depending on your dosage, whether you’re taking the Ozempic pill vs. the injection, and whether or not you have type 2 diabetes.

For example, in studies of semaglutide at doses higher than Ozempic's approved maximum, people without type 2 diabetes lost about 6% of their body weight after three months, while it could potentially take longer to see similar results with the pill.

Meanwhile, people with type 2 diabetes may lose approximately 5–8 pounds — or about 2%–3% of their body weight — after 26 weeks (six months) on the Ozempic pill. Those taking the injection may lose about 4%–5% of their body weight in 30 weeks. 

Here’s a quick look at how much weight you can lose on Ozempic: 

• First Month: Up to about 2% of starting body weight

• Months 2–6: Between 4%–5% of starting body weight

• Months 6–12: Between 5%–7% of starting body weight

Some of these figures come from studies of semaglutide at doses used for weight management, which can be higher than Ozempic's approved maximum dose for type 2 diabetes.

All in all, Ozempic and other semaglutide medications produce significantly more weight loss than eating habits and exercise alone. In one study of people with type 2 diabetes comparing a higher dose of semaglutide to a placebo, those who took the placebo lost less than 4% of their body weight over 68 weeks, while those taking semaglutide lost almost 10%.

Whether you are taking Ozempic to manage type 2 diabetes, or off-label to manage weight, or both, it's important to remember that the medication is most effective when combined with lifestyle changes, such as eating habits 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 11–14 pounds, within the first three months of taking injectable 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 Ozempic, which does not induce significant weight loss in many people. It takes about three to four months to reach a maintenance dosage. “So, if you don't see weight loss in the first four weeks, that can be normal too,” Dr. Tchang says.

Translation: It's difficult to determine how much weight you can lose in a month on Ozempic because you haven’t reached maintenance dosing yet. That being said, we can consider additional findings from studies of semaglutide at weight-management doses, such as a 2022 real-world study, and do some math:

• The mean baseline weight (i.e. participants’ average starting weight) was 118.1 kg or 260.4 pounds. 

• After three months on semaglutide at a weight-management dose, participants had lost an average of 5.9% of their body weight, which in this study represented around 15 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.

That's a similar monthly pace to the figure Dr. Tchang cites, though from a study using a higher, weight-management dose of semaglutide than Ozempic's approved maximum. There's no universal answer, and everyone's experience is different, but this gives a rough sense of what's realistic in a month on semaglutide.

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 medication, and whether or not you implement lifestyle modifications (e.g. eating habits, exercise).

• Diabetes status: People who have type 2 diabetes, for example, tend to lose less weight when treated with Ozempic than people without the condition. 

• Dose of Ozempic: The amount of weight a person loses while using Ozempic tends to be dose-dependent. In other words, people taking lower doses tend to lose less weight than people taking higher doses. 

• Starting body weight: People who weigh more when they start taking Ozempic may lose more pounds overall than people with lower body weights.

• Lifestyle changes: Ozempic is meant to be used with a reduced-calorie eating plan and increased physical activity. Research suggests that people who implement these changes may experience more long-term weight loss success.

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 without medication, your eating habits 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, 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. These spikes can negatively impact insulin sensitivity, which 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. 

If you’re having difficulty getting enough protein, Dr. Tchang says replacing one meal with a protein shake can 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. 

And here’s a pro tip: Avoid protein shakes with large amounts of added sugar that can disrupt your calorie goals and cravings.

2. Change how you eat

Ozempic works best when combined with healthy eating habits 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 suggests that 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: start by eating without distractions (i.e. not at your desk or in front of the TV) and focus on how the food tastes and feels in your mouth.

Dr. Tchang says taking Ozempic in combination with a healthcare provider, dietitian, or nutritionist’s advice can be another great way to maximize your weight loss efforts. 

"In one clinical trial, about one in three people achieved at least 20% weight loss — or 37 pounds on average — with meal replacement protein shakes; a low-calorie diet  of 1,200–1,800 calories a day, depending on your body's needs; physical activity, slowly ramped up to 200 minutes per week; and multiple visits with a dietitian-nutritionist," Dr. Tchang says.

With Ro's Body membership, for example, you can access 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 part 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 or you’re 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 on high-calorie foods. 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 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 also 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 polyendocrine metabolic ovarian syndrome (PMOS, formerly known as 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 provider about your treatment plan. Some diabetes medications can cause weight gain, she says, including sulfonylureas and insulin. "Optimizing your medication regimen to avoid weight-promoting medications while still keeping diabetes under control is key," Dr. Tchang adds.

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 with Ozempic, although they're 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. Ozempic also carries a boxed warning from the FDA for thyroid C-cell tumors. Semaglutide made it more likely for these tumors to occur in animal studies. It’s unclear if the same applies to humans, but because of this, Ozempic isn’t recommended for anyone with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).  

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.

Start your journey

According to clinical trials, people taking Ozempic can lose up to 5%–10% of their body weight and sometimes more. Ultimately, however, the answer to the question, “how much weight can you lose on Ozempic?” varies from person to person. 

• The amount of weight you lose on Ozempic can depend on the dose, your starting weight, and other underlying medical conditions, such as type 2 diabetes. 

• Ozempic starts working quickly, with people noticing appetite changes and weight loss within the first three months of taking it.

There are many evidence- and expert-backed strategies for maximizing weight loss while taking Ozempic, from maintaining healthy eating habits to getting continual support from a healthcare provider.
