What Is Liraglutide?
Liraglutide is a medicine used to help people with type 2 diabetes stabilize their blood sugar. Type 2 diabetes is when the blood sugar (glucose) level becomes abnormally high.
It happens because your body either doesn't use insulin properly or doesn't make enough of it. Insulin helps your body's cells use sugar for energy. When sugar stays in your blood instead of entering your cells, it can lead to various health problems over time.
Liraglutide belongs to the category of drugs called GLP-1 receptor agonists. These drugs mimic the effects of a natural hormone called GLP-1, which regulates blood sugar levels after meals. When you eat, GLP-1 stimulates insulin release from the pancreas, which helps lower blood sugar.
Liraglutide acts like GLP-1, encouraging the pancreas to release insulin when needed and reducing the amount of sugar produced by the liver. This results in better control of blood sugar levels throughout the day.
Additionally, liraglutide helps your weight loss journey by making you feel full and satisfied, leading to less eating. Weight loss is all about calories in and calories out. Liraglutide works by making it easier to limit how many calories you take in.
We discuss liraglutide's role as an appetite suppressant in more detail in our article: Do Appetite Suppressants Work?
How Does Liraglutide Work?
As mentioned, liraglutide helps control the amount of sugar in our blood. It does this by telling our body to release insulin. It also slows down how quickly our stomach handles food and crushes our appetite.
Let's break it down further:
- Blood Sugar Regulation: Liraglutide triggers insulin release from the pancreas, which helps transport glucose (sugar) from the bloodstream into cells. This reduces blood sugar levels, improves overall glycemic control, and can reduce the risk of cardiovascular disease.
- Slowed Digestion: Liraglutide slows down the emptying of the stomach's contents into the intestines. This helps in reducing the rate at which glucose enters the bloodstream after meals, leading to more stable blood sugar levels.
- Appetite Control: By acting on the brain's appetite-regulating centers, liraglutide helps individuals feel fuller and more satisfied after eating, reducing overeating and promoting weight loss.
- Liver Glucose Production: Liraglutide reduces the liver's production of glucose, which is an essential factor in managing glucose levels, especially during periods of fasting. Early research has also shown improvement in patients with nonalcoholic fatty liver disease.
- Weight Loss Promotion: Beyond its effects on diabetes management, liraglutide's impact on appetite and digestion makes it an effective tool for weight loss and reducing body mass index. The slower stomach emptying and increased fullness contribute to reduced calorie intake and sizeable weight reduction.
It's important to note that liraglutide is administered as a subcutaneous injection (under the skin) to ensure its direct entry into the bloodstream. An injection bypasses the digestive system, allowing for more controlled and efficient action.
What Is Semaglutide?
Semaglutide, like liraglutide, is a synthetic compound that belongs to a group of pharmaceuticals known as GLP-1 receptor agonists. These medicines are designed to help with type 2 diabetes and weight management.
Semaglutide also helps control glucose levels, insulin release, appetite, and how fast our stomach digests food, making it helpful in dealing with diabetes and chronic weight management issues.
You might have heard of semaglutide by its brand names, Ozempic and Wegovy. Ozempic is mainly used to manage diabetes, while Wegovy is designed to help with weight loss. Both versions are given through shots under the skin. The cool thing is that you only need to take them once a week, which makes things more convenient.
Semaglutide is currently one of the hottest drugs on the planet for its weight loss effects. Some have even called it a "miracle" weight loss drug. By controlling blood sugar, improving how insulin works, making you feel full, and slowing down digestion, semaglutide offers a comprehensive approach to weight loss.
As we dive into its features, perks, and things to think about, we'll see how semaglutide has the potential to transform how we deal with diabetes and achieve lasting weight loss.

How Does Semaglutide Work?
Semaglutide works very similar to liraglutide. It is like an intelligent helper for your body, controlling blood sugar, appetite, and weight control.
Let's take a simple look at how it works:
- Blood Sugar Control: When you have diabetes, your sugar levels can go haywire. Semaglutide steps in and tells your body to release more insulin. Insulin acts like a key, letting sugar into your cells, which helps lower sugar levels in your blood.
- Slow and Steady Digestion: Semaglutide helps control energy intake regulation, slowing down the speed at which your stomach empties. This means sugar enters your bloodstream more gradually, preventing those quick spikes in sugar levels.
- Fullness: Sometimes, our brains don't get the message that we're full, and we eat more. Semaglutide communicates with your brain to signal it's full sooner so you don't overeat.
- Weight Loss Support: By blunting appetite, semaglutide makes it easier to control your eating habits leading to weight loss and reducing body mass index.
In a nutshell, semaglutide is like a helper that talks to your body and brain to keep your sugar levels steady, make you feel full faster, and support your weight goals. It's given as a shot and gets to work helping you manage diabetes and keep your weight in check.
Semaglutide vs Liraglutide: What's The Difference?
Obviously, as we have already discussed, there are a ton of similarities between semaglutide and liraglutide. Most notably, both drugs help control blood sugar and can aid in weight loss.
The main difference is how often you take them. Semaglutide is usually taken once a week, while liraglutide is once daily. Also, semaglutide tends to be stronger, so you might need a lower dose than liraglutide.
Let's take a closer look.
Dosing Schedule
Both medications can have long-term benefits, so you may need to take them for quite a while - even for the rest of your life - to keep enjoying the positive effects. However, if you are taking them for weight loss, once you reach your goal, you can transition off of it.
For semaglutide: It's usually taken once a week, which is nice because you only get a shot one time a week. You'll likely keep taking it for as long as your doctor recommends to manage your diabetes or weight.
For liraglutide: It's typically taken once daily, so you have to give yourself a shot every day. Just like with semaglutide, you'll likely keep using it as long as your doctor suggests to control your diabetes or weight in check.
Here is a weekly breakdown of the standard dosing schedule. Please note that Saxenda is a form of liraglutide, while Wegovy and Ozempic are forms of semaglutide.

Liraglutide vs Semaglutide For Weight loss
Both liraglutide and semaglutide are very effective weight loss treatments, particularly if you have excess body weight. As mentioned, in addition to controlling blood glucose, they reduce appetite. Dieting is hard, and being unable to stick it out long-term derails most people's fat loss efforts. Using liraglutide and semaglutide as an appetite suppressant makes them so effective for weight loss.
Although both are effective, the preliminary research tends to favor semaglutide. A 2022 study comparing the two drugs shows participants in the 2.4mg semaglutide treatment group have lost almost 16% of their body weight, compared to just over 6% in the 3mg liraglutide group1.
Here is one Reddit user's experience with semaglutide:
"7 weeks and down 23 pounds. I workout 6 days a week and eat what I want for the most part... My portions are naturally much smaller. I was on .25 for 4 weeks then on .5 dose since then. I won't be increasing the dose as the .5 is working so well. I've never ever ever lost weight this easily. Love this med. Starting weight 200 pounds and now at 177 pounds!" (source)
