How much weight can you lose on Wegovy?

Wegovy (semaglutide) can be a meaningful option when it comes to weight loss and management for people with overweight or obesity. But just how much weight can you lose on Wegovy? 

To answer that question, we reviewed the research and talked to healthcare providers who specialize in obesity medicine. Read on as we share the average weight loss on Wegovy and offer tips for maximizing your weight loss on the medication.

How much weight you can lose on Wegovy depends on several factors, including your dosage, starting weight, and adherence to lifestyle changes such as an eating plan and exercise. On average, however, people taking Wegovy lose around 13%–15% of their body weight in less than a year and a half.

Here’s a quick look at what studies have found regarding the average weight loss on Wegovy: 

• A large-scale clinical trial of over 1,900 adults found that injectable Wegovy produced an average weight loss of 14.9% (33.7 pounds) over 68 weeks (about a year and a half). Those taking a placebo lost just 2.4% (5.7 pounds) in the same time period. 

• A clinical trial of the Wegovy pill found that it produced an average weight loss of 13.6% (31.3 pounds) over 64 weeks (about a year and three months). Those taking a placebo lost just 2.2% (4.8 pounds) in the same time period.

• One study looked at the effects of combining Wegovy with an intensive behavioral program that included diet and exercise counseling. Those who followed only diet and exercise changes lost 5.7% of their starting weight in 68 weeks. Those who took Wegovy alongside behavioral modifications, on the other hand, lost 16%.

• A longer-term two-year study found that people experienced an average weight loss of 15.2% on Wegovy, compared with just 2.6% for those taking a placebo.

“Weight loss on Wegovy varies from one person to the next, but clinical trials provide general expectations,” says Audrey Wells, MD, a physician double-board certified in sleep medicine and obesity medicine.

How much weight can you lose with Wegovy in one month?

People lose around 2% of their body weight after one month of taking Wegovy.

• On the Wegovy injection, people lose at least 2%, and sometimes close to 3%, of their body weight in a month, according to research. 

• On the Wegovy pill, people lose about 2% of their body weight in a month, according to research. 

“In the first month [of Wegovy], one can expect between 2% and 4% total body weight loss with a typical dose escalation,” Dr. Wells says. “Some patients lose 5% or more of their total body weight; less weight loss may be related to a slower ramp-up with the medication.”

Wegovy follows a ramp-up dosing schedule to help your body adjust to the medication and its common side effects. It can take up to four months — or longer — to reach your final maintenance dose. For this reason, most studies observe a longer period than one month, with 68 weeks (about a year and a half) being a typical time frame. During the first month, most people are still on the lowest dose of Wegovy (0.25 mg). 

Most people notice weight loss within the first month of taking Wegovy. In clinical trials, people lost around 2% of their body weight in that time frame. Weight loss on Wegovy generally begins fairly quickly, although individual results may vary. 

In clinical trials, nearly a third of the participants lost 20% or more in a year and a half.  “Weight loss usually peaks around the year mark,” Dr. Wells says. “A higher body mass index, or BMI, often leads to more pounds lost.”

To maximize weight loss with Wegovy, it’s important to:

• Follow a balanced eating plan rich in fiber and protein

• Exercise regularly, with a mix of cardio and strength training

• Get quality sleep (7–9 hours) every night

• Manage stress levels

“Weight loss medications should not be used in isolation,” says Supriya Rao, MD, a quadruple board-certified physician specializing in obesity medicine and lifestyle medicine. “They’re one tool in an entire toolbox of options, and they’re great options.” 

That said, there are a few tactics you can implement to try to boost your results. 

1. Upgrade your eating habits

Weight loss medications like Wegovy work best when combined with a reduced-calorie diet. But it’s not just about eating fewer calories; it’s also about making sure the calories you do eat pack a bigger nutritional punch. 

“Where diet is concerned, I recommend three things: eat as many unprocessed foods as possible, make sure you get enough protein to support your muscles, and make sure you get enough fiber,” Dr. Wells says. 

Dr. Rao recommends adopting a Mediterranean diet, which focuses on healthy fats from nuts and olive oil, lean proteins such as poultry and fish, and high-fiber fruits and vegetables. 

It’s also a good idea to reduce your alcohol consumption while taking Wegovy, she adds. Alcohol can interfere with weight loss by adding empty calories and potentially increasing appetite. 

2. Develop a regular exercise routine

Described as “the best for weight maintenance” by Dr. Wells, strength training exercises — such as squats, deadlifts, and resistance band work — can help you preserve the muscle mass while continuing to lose weight on Wegovy. As a bonus, building muscle mass can increase your metabolism.

Current expert guidelines from the American College of Sports Medicine and The American Heart Association recommend strength training at least twice a week and at least 150 minutes of cardiovascular exercise for weight management.

For optimization, Dr. Rao recommends an exercise routine that includes:   

• Strength training three times a week 

• Walking 10,000 steps per day 

• An additional cardio or yoga session

3. Get better (and more) sleep

Lack of sleep can increase the amount of muscle you lose along with fat, which can slow your metabolism, Dr. Wells says. Too little sleep can also disrupt hunger hormones, leading to more snacking and weight gain.

To support your weight loss efforts, Dr. Rao recommends prioritizing getting 7–9 hours of restful, uninterrupted sleep per night. “Create a new shutdown sequence. Improve your sleep hygiene, and get technology out of the bedroom,” Dr. Rao says.

Other sleep hygiene tips (that may help boost how much weight you can lose on Wegovy) include:

• Following a consistent sleep schedule

• Practicing relaxation exercises before bed

• Using your bed for sleep and sex only

• Avoiding alcohol, heavy meals, and caffeine in the evening

• Quitting smoking

4. Keep your stress levels in check

Stress can worsen sleep quality and contribute to weight gain. Like people who don’t get enough sleep, those who are chronically stressed may be more prone to overeating, especially high-calorie, sugary foods. 

Mindfulness exercises can help people manage stress and stay grounded in the present moment, focusing on thoughts, senses, and feelings without judgment. Popular options include:

• Meditation, including visualization and guided meditation

• Deep breathing exercises

• Progressive relaxation exercises

5. Build your support network

Working with other health professionals alongside the healthcare provider who prescribed Wegovy can set you up for more success on your weight loss journey. These may include a personal trainer, nutritionist or dietitian, or mental health professional for managing stress.

Dr. Rao recommends that her patients meet with a nutritionist to optimize the amount of fiber, protein, and macronutrients they eat and reduce their intake of processed foods and animal proteins. 

Finding a weight loss “buddy” can also be helpful. A 2018 study of more than 700 people in an online behavioral program found that those who paired up with buddies lost more weight than those who went through the program alone.

 “Having that camaraderie of going through this with somebody and having familial support can help people maximize their weight loss,” Dr. Rao says.

Clinical trials show meaningful weight loss results on Wegovy, but it’s worth remembering that how much weight you can lose on Wegovy differs from person to person. Factors such as your eating habits, exercise, sleep, and stress levels can all play a role in your overall results.

• Weight loss on Wegovy typically begins early in treatment. Most people lose 2% of their body weight or more in the first month. 

• Total weight loss on Wegovy ranges from 13% to 15% over a year and a half. Nearly a third of people lose 20% or more. 

• Wegovy is also available as a pill, which has been shown to produce similar results to the injectable — with people losing an average of 13.6% of their body weight over about a year and three months in clinical trials.

• Healthy eating and exercise are key to maximizing weight loss on Wegovy. Experts recommend a nutrient-dense, high-fiber, and protein-rich eating plan, such as the Mediterranean diet. Exercise, especially strength training, can help preserve muscle and sustain long-term weight loss. 

• Your sleep quality and stress levels can also impact weight loss success on Wegovy. Poor sleep and stress both contribute to overeating and weight gain. Focus on getting 7-9 hours of restful sleep per night and explore mindfulness techniques like meditation, deep breathing, and yoga. 

• Having a strong support system in place can also improve weight loss on Wegovy. In addition to your healthcare provider, working with health professionals and finding a weight loss buddy can help you stay motivated to build healthy habits and work toward your weight loss goals.
