      The Evolution of GLP-1 Agonists in Weight Management

      The Evolution of GLP-1 Agonists in Weight Management
      Posted on June 28, 2024

      We can’t deny there has been a lot of hype around weight loss medications in the past couple of years. So, what is all the hype about, and how did it start?

      Among the most significant advancements in this field are GLP-1 agonists, such as Semaglutide and Tirzepatide. These medications have revolutionized the approach to weight loss and management.

      Let’s explore the history and development of GLP-1 agonists and what’s in store for the future.

      Understanding GLP-1 Agonists

      First, let’s get a better understanding of what a GLP-1 agonist is and its role in weight loss.

      GLP-1, or Glucagon-Like Peptide-1, is a hormone produced in the intestines in response to food intake. It plays a critical role in regulating blood sugar levels and appetite. By stimulating insulin secretion, inhibiting glucagon release, slowing gastric emptying, and promoting satiety, GLP-1 helps maintain healthy blood sugar levels and reduces hunger.

      GLP-1 agonists are medications that mimic the action of this hormone. Initially used primarily for managing type 2 diabetes, these drugs have recently gained attention for their weight loss benefits.

      Early Developments in GLP-1 Agonists

      The first GLP-1 agonist, Exenatide (Byetta), was approved in 2005 and may surprise you as to where it comes from. Derived from the saliva of the Gila monster, a lizard native to the southwestern United States, Exenatide was initially used to improve blood sugar control in patients with type 2 diabetes. Turns out, it showed moderate weight loss effects as well.

      In 2010, Liraglutide, known as Victoza for diabetes, hit the market along with another leader in GLP-1 agonists, Saxenda, in 2014. These drugs marked a significant step forward in what was possible for weight management with medication. Liraglutide's approval for weight management indicated a shift towards using GLP-1 agonists explicitly for this purpose, highlighting their dual benefits in controlling blood sugar and reducing weight. This medication did require daily injections, however.


      Fast forward, and here we are with the now well-known weight loss medication- Semaglutide. Semaglutide represents a major advancement in GLP-1 agonist development. Approved for type 2 diabetes under the brand name Ozempic in 2017 and for chronic weight management as Wegovy in 2021, Semaglutide is administered weekly, offering a more convenient option compared to daily injections. Clinical trials have shown that Semaglutide leads to substantial weight loss, with patients losing an average of 15-20% of their body weight. Additionally, Semaglutide has been found to improve cardiovascular outcomes, making it a comprehensive treatment option for obese patients with related health issues.

      So, how does Semaglutide work? Semaglutide involves several key processes:

      • Enhancing insulin secretion: This helps the body regulate blood sugar levels more effectively.
      • Inhibiting glucagon release: By reducing the release of glucagon, a hormone that raises blood sugar levels, Semaglutide helps maintain better glucose control.
      • Slowing gastric emptying: This slows down the rate at which food leaves the stomach, leading to reduced appetite and lower caloric intake.
      • Activating brain regions associated with satiety: Semaglutide influences brain areas that control feelings of fullness, helping patients feel satisfied for longer periods, which is crucial for effective weight management.


      Introduced in 2022 under the brand name Mounjaro, Tirzepatide is a medication that combines the effects of GIP (Glucose-Dependent Insulinotropic Polypeptide) and GLP-1 receptor agonists. This dual-action mechanism offers superior blood sugar control and weight loss benefits compared to previous treatments. By enhancing the insulinotropic effects of GLP-1, GIP amplifies Tirzepatide's efficacy, making it a promising option for patients with type 2 diabetes and obesity.

      Clinical trials have demonstrated unprecedented weight loss results with Tirzepatide, with some patients losing up to 25% of their body weight. In addition to its weight loss benefits, Tirzepatide also provides improved glycemic control, offering a comprehensive solution for managing diabetes and obesity.
