GLP-1 Agonists: More Than Just A Weight Loss Drug?

You might not be familiar with the term GLP-1 agonist, but you most likely have heard about semaglutide (commonly referred to by its brand name Ozempic). These popular weight-loss drugs fall into a broader category of drugs called GLP-1 agonists.

So, if you happen to see a headline about a “new” weight loss drug called GLP-1 agonist, it’s probably not new. They are likely referring to semaglutide, which has been making waves for some time now, catching the attention of notable personalities and the Hollywood elite, who have openly discussed their experiences with different variants of the drug.

Semaglutide and its branded counterparts have gained widespread recognition for their significant contributions to medical weight loss. They may be marketed under different names, but they all share the same fundamental mechanism as GLP-1 agonists, which offer a spectrum of benefits extending beyond weight management.

In this article, we will explain what GLP-1 agonists are, how they work, the various types available, which is best for weight loss, where to safely obtain them, and how other GLP-1 agonists are used to treat other medical conditions.

What are GLP-1 Agonists?

To understand what GLP-1 agonists are and what they do, you first need to know what GLP-1 is. 

GLP-1 (glucagon-like peptide-1) is a natural hormone produced in the gut in response to food consumption. Its primary function is to regulate blood sugar levels by stimulating the release of insulin while simultaneously reducing the production of glucagon, a hormone responsible for elevating blood sugar levels.

But there’s more to GLP-1 than just blood sugar management. Its influence extends to appetite and satiety regulation. Following a meal, GLP-1 signals the brain, conveying a sense of fullness and effectively reducing food intake.

GLP-1 agonists are medications designed to replicate the actions of natural GLP-1, amplifying its effects. By activating the same receptors that natural GLP-1 binds to, these agonists enhance its regulatory functions.

In medical conditions such as type 2 diabetes, GLP-1 agonists help regulate blood sugar levels by stimulating insulin secretion and suppressing glucagon release. Additionally, they have been shown to slow down gastric emptying, contributing to improved blood sugar control.

In other medical conditions, such as non-alcoholic fatty liver disease (NAFLD) and cardiovascular disease, GLP-1 agonists have demonstrated beneficial effects. They may help reduce liver fat content and inflammation in individuals with NAFLD, potentially slowing disease progression. 

Moreover, GLP-1 agonists have been associated with cardiovascular benefits, including reductions in major adverse cardiovascular events like heart attack and stroke in patients with type 2 diabetes and established cardiovascular disease.

In the context of weight loss, GLP-1 agonists offer additional benefits. By mimicking the effects of GLP-1 on appetite and satiety, these medications help control cravings, reduce food intake, and promote a sense of fullness, making it easier to adhere to a calorie-controlled diet. They may also have metabolic effects such as improving insulin sensitivity, further supporting weight loss efforts.

The most popular GLP-1 agonist for weight loss is semaglutide. Originally designed by Novo Nordisk to assist individuals with type 2 diabetes in managing blood sugar levels, the drug’s unexpected side effect of significant weight loss quickly thrust it into the spotlight, making it a highly sought-after weight loss medication.

Types of GLP-1 Agonists

GLP-1 agonists are a compelling class of drugs, offering not only effective blood sugar regulation for diabetics, but also have significant benefits in promoting weight loss. Because various drugs fall under the GLP-1 agonists category, it can be a bit confusing to know which GLP-1 agonist you should consider for weight loss. 

Below are some of the most common types of GLP-1 agonists and what they are used for:


Semaglutide is a potent and long-acting GLP-1 receptor agonist that has gained significant attention in weight management and diabetes care. It is available in both injectable and oral formulations. 

Semaglutide is the active ingredient in several brand-name medications, including Ozempic® and Wegovy™ injections and Rybelsus™ tablets. Despite different brand names, these products contain the same active ingredient, semaglutide, and work in a similar manner to regulate blood sugar levels, suppress appetite, and promote weight loss.

Semaglutide is often prescribed when individuals struggle to lose weight despite adhering to diet and exercise regimens. However, its usage is typically reserved for those with a body mass index (BMI) over 30. It’s remarkably effective for obese individuals, to the extent that it’s being considered as an alternative to bariatric surgery for some patients.

Liraglutide is a GLP-1 agonist available in injectable form under the brand names Victoza® and Saxenda®. Victoza®  is prescribed for the management of type 2 diabetes, helping to improve blood sugar control by stimulating GLP-1 receptors. Saxenda® is also used for diabetes management but is sometimes also used for weight management. 

Both formulations of liraglutide work by mimicking the action of GLP-1, enhancing insulin secretion, and reducing blood sugar levels in individuals with diabetes. A significant disadvantage of liraglutide for weight loss is that it requires more injections than semaglutide. Additionally, clinical trials show that semaglutide results in more weight loss, on average, compared to liraglutide.


Exenatide is another GLP-1 agonist. It is available in short-acting (Byetta®) and long-acting (Bydureon®) formulations. These formulations of exenatide are only approved for diabetes management. They mimic the effects of natural GLP-1, promoting insulin secretion and slowing down gastric emptying to improve blood sugar control in individuals with diabetes.


Dulaglutide is a once-weekly GLP-1 receptor agonist available under the brand name Trulicity®. It is primarily used for managing type 2 diabetes. Dulaglutide works by activating GLP-1 receptors, stimulating insulin secretion, and suppressing glucagon release to improve glycemic control in individuals with diabetes.


Lixisenatide is a short-acting GLP-1 agonist administered once daily before the first meal of the day. It is available under the brand name Adlyxin® and is primarily used to treat type 2 diabetes.

Lixisenatide acts by mimicking the action of GLP-1, enhancing insulin secretion and reducing blood sugar levels in individuals with diabetes, particularly after meals.

How Glp-1 Receptor Agonists Can Help You Lose Weight

GLP-1 agonists are synthetic compounds designed to mimic the actions of the natural hormone GLP-1. Leveraging the body’s inherent regulatory mechanisms for blood sugar and appetite control, medications like semaglutide offer a multifaceted approach to weight management. This makes them a promising option for individuals grappling with obesity and associated metabolic conditions.

GLP-1 receptor agonists approved for weight loss (semaglutide) offer a holistic approach to weight loss by targeting multiple facets of metabolism and appetite regulation. From reducing hunger and calorie intake to improving insulin sensitivity and long-term weight maintenance, these medications hold significant potential for individuals looking to achieve and maintain a healthier body weight.

Here are the primary ways GLP-1 receptor agonists such as semaglutide can help aid in weight loss:

Appetite Suppression

GLP-1 agonists work by activating receptors in the brain that regulate hunger and satiety signals. This leads to a reduced appetite, making it easier to stick to a calorie-controlled diet without feeling constantly hungry or deprived.

Delayed Gastric Emptying

These medications slow down the rate at which food empties from the stomach into the small intestine. This prolongs the feeling of fullness after a meal, helping to prevent overeating and reducing the desire for snacks or additional portions.

Calorie Intake Reduction

By curbing appetite and promoting a sense of fullness with smaller meals, GLP-1 agonists naturally lead to a decrease in calorie intake. This caloric deficit is essential for weight loss as it forces the body to burn stored fat for energy.

Improved Insulin Sensitivity

Some GLP-1 agonists have been shown to enhance insulin sensitivity, which means your body can more effectively use glucose for energy rather than storing it as fat. This can be particularly beneficial for individuals with insulin resistance or type 2 diabetes, who often struggle with weight management.

Inhibition of Glucagon Release

GLP-1 agonists not only stimulate insulin release but also inhibit the secretion of glucagon, a hormone that raises blood sugar levels. By promoting a balance between insulin and glucagon, these medications help regulate blood sugar levels and reduce the risk of overeating due to blood sugar fluctuations.

Potential Effect on Food Cravings

While still under investigation, emerging evidence suggests that GLP-1 agonists may also impact food cravings and food reward pathways in the brain. This could further support adherence to a healthy diet by reducing the desire for high-calorie, indulgent foods.

Long-Term Weight Maintenance

Beyond just initial weight loss, GLP-1 agonists have shown promise in helping individuals maintain their weight loss over the long term. By addressing both the physiological and behavioral aspects of weight management, these medications offer a comprehensive solution for sustainable results.

Other Issues GLP-1 Agonists Can Treat

While GLP-1 Agnostics such as semaglutide have made headlines for their ability to help people lose weight, they are used for health issues that extend far beyond simply shedding pounds. These medications also hold significant promise in addressing a spectrum of metabolic and systemic conditions.

Health issues that GLP-1 agonists are known to effectively address include:

Type 2 Diabetes Management

GLP-1 agonists are widely used in the management of type 2 diabetes. By enhancing insulin secretion in response to meals and suppressing glucagon release, these medications help control blood sugar levels and improve glycemic control.

Cardiovascular Risk Reduction

Several GLP-1 agonists have demonstrated cardiovascular benefits beyond glycemic control. They have been shown to reduce the risk of major adverse cardiovascular events, including heart attack, stroke, and cardiovascular death, in patients with type 2 diabetes and established cardiovascular disease.

Blood Pressure Regulation

Some GLP-1 agonists have been associated with modest reductions in blood pressure, which can be beneficial for individuals with hypertension or those at risk of cardiovascular complications. Lowering blood pressure levels helps protect against heart disease, stroke, and other cardiovascular conditions.

Improvement in Lipid Profile

GLP-1 agonists may also have favorable effects on lipid metabolism, including lowering levels of triglycerides and LDL cholesterol (the “bad” cholesterol) and increasing levels of HDL cholesterol (the “good” cholesterol). These lipid-modifying effects contribute to overall cardiovascular risk reduction.

Non-Alcoholic Fatty Liver Disease (NAFLD)

There is growing evidence to suggest that GLP-1 agonists may have therapeutic potential in the management of non-alcoholic fatty liver disease, a condition characterized by excess fat accumulation in the liver. By improving insulin sensitivity and reducing liver fat content, these medications can help alleviate liver inflammation and fibrosis associated with NAFLD.

Polycystic Ovary Syndrome (PCOS)

GLP-1 agonists have shown promise in the treatment of polycystic ovary syndrome, a common hormonal disorder in women of reproductive age. These medications can help improve insulin sensitivity, regulate menstrual cycles, and reduce symptoms such as hirsutism (excessive hair growth) and acne in women with PCOS.

Neurological Disorders

Emerging research suggests that GLP-1 agonists may have neuroprotective effects and could potentially be used in the treatment of neurodegenerative disorders such as Alzheimer’s disease and Parkinson’s disease. These medications may help reduce inflammation, promote neuronal survival, and improve cognitive function in affected individuals.
