Semaglutide For Weight Loss: How It Works And What To Expect
Learn how semaglutide works and how much weight it can help you lose. Our experts review the research so you can know exactly what you can expect from your treatment.
Thinking about, or already on, a weight loss drug like Ozempic, Wegovy, Compounded Semaglutide or Mounjaro? You might also be wondering what happens when you stop. To get the most out of your investment into your health, keep your weight loss on track, and take positive steps to avoid rebound weight gain or losing muscle mass – here’s what our Levity experts recommend you to do.
Semaglutide injections (GLP-1 receptor agonists) like Ozempic are a type of diabetes and weight loss treatment. They work by controlling your appetite and food cravings, as well as balancing your blood sugar levels. If you’ve struggled to lose weight through diet and exercise alone, these drugs can give you an extra boost to start losing weight, get motivated and stick to a sustainable plan. (1)
To answer this question, here are two studies that look into what happens after a person stops taking semaglutide (the active ingredient in GLP-1 agonist weight loss medications like Ozempic).
A study called the ‘Step 1 Trial’ involved 1961 non-diabetic participants who had either:
Participants were divided into two groups. One was given semaglutide, the other was given a placebo. By 68 weeks, the mean weight of participants in the Semaglutide group dropped by 14.9%. The placebo group only saw an average weight loss of 2.4%.
More research was done on 327 people involved in the original trial. When the group taking semaglutide stopped their medication, from weeks 68-120 they regained 11.6% of their body weight back. The placebo group regained 1.9% of their body weight. The semaglutide group therefore lost 5.7% overall, whereas the placebo group lost 0.1% overall.
In summary, those who took semaglutide did regain some weight – but there wasn’t a complete reversal of the medication’s effects. (2)
In another double-blind study, which is considered the gold standard method in clinical trials, the ‘Step 4 Trial’ study also found that everyone who stopped using GLP-1 medications gradually regained some of the weight they lost after 20 weeks. In comparison, those that continued using the medication for 68 weeks kept losing weight. So regaining weight is a potential side effect once you stop the medication. (3)
Yes, some people can keep the weight off. But we want to caveat this by saying, everyone is different, and there’s no shame in regaining the weight after you stop. Obesity is a chronic disease. And, like high blood pressure, this medication can be taken for life to control it.
If you do want to stop, and give yourself the best chance at maintaining your weight loss goals, you’ll need to do some preparation.
There are diet, exercise and healthy lifestyle changes you can make. We need to get your body in the best condition while you’re on Ozempic, so you have the highest chance of managing and losing weight after you stop.
Any weight loss, whether you use Ozempic or not, will involve both muscle and fat loss.
While dieting, we want to avoid muscle loss as much as possible for several reasons.
So throughout your Ozempic journey, it’s really important to continue building muscle.
Weight training or resistance training is vital for holding onto and building muscle. You don’t need to be lifting heavy in the gym every day, but try to move every major body part 2-3 days a week. That could look something like (but isn’t limited to):
Upper Body Push: Arm and back exercises like push ups, chest press, overhead press, tricep dips and planks.
Upper Body Pull: Arm and back exercises like (assisted) pull ups, bent over rows and bicep curls.
Hip And Thigh Hinging: Front or back squats, step-ups, deadlifts and lunges.
If you’ve never done these kinds of exercises before or you have injuries, consider getting a professional trainer. They can give you personalized tips, tailor exercises to your fitness level and check your form, so your workouts work for you. (5)
Semaglutide injections mimic the hormones in your gut that help you feel fuller for longer and balance your blood sugar levels. This is an absolute game-changer for consistent weight loss, but you still need to fuel your body with the right nutrients at mealtimes to stay healthy and energized.
To maintain and build muscle, aim to eat around 0.8g of protein per kilogram of your body weight. So if you weigh 100kg (or 220 pounds), you’ll want to aim for around 80g (or 2.8oz) of lean protein per day.
Pairing your protein-rich meal with fiber can help stabilize your blood sugar too. (6)
We’ve all heard of the term “eating the rainbow”, but here’s why eating a variety of fresh or frozen fruits and vegetables will help when you’re losing weight, and after you stop taking semaglutide medications like Ozempic.
A good rule of thumb is to have five to six cups per day. Find ones you think are delicious and switch up the cooking methods, eat them cooked or raw, so you’re absorbing a variety of nutrients. (7)
What’s more, the better your gut microbiome functions, the more it can support your body’s production of the hormones that tell you when you’re full.
Find it hard to drink enough water? That’s not uncommon at all. In fact, another side effect of semaglutide injections is that it can make you feel less thirsty. (1) Plus, generally it can be hard for most of us to drink enough water anyway – even without Ozempic.
But water keeps every system in your body working the way it should, including your digestion. According to Harvard Medical, you should try to drink at least 4-6 cups of plain water every day. (8)
In a study, researchers found that people who drink more plain water may eat fewer total calories, drink fewer sweetened drinks, and take in less fat, sugar, salt, and cholesterol. Adding just one to three extra cups of plain water a day could make you eat up to 205 fewer calories. Over time that could help with weight loss. (9)
You may need to drink more plain water if:
You are moving more: While exercising, you lose more water through sweating and may need to drink more.
It’s hot outside: If the temperatures are high outside, you might sweat more and feel thirstier faster.
You are older: As we age, we’re not as good at sensing how thirsty we are compared to when we’re younger. (8)
Just because Ozempic can make weight loss easier, doesn't mean it's time to kick back and relax. While you’re still on the medication, you’ll be giving yourself the best chance of success by practicing healthier habits. However, if you stop and regain weight, don’t forget this is normal for many people, too.
