GLP-1 receptor agonists have transformed the landscape of medical weight loss. With average weight loss of 15-25% of body weight, these medications represent a paradigm shift in obesity treatment.

How GLP-1 Medications Work

These medications mimic the GLP-1 hormone, which regulates appetite, blood sugar, and gastric emptying. By activating GLP-1 receptors in the brain, they reduce hunger and increase feelings of fullness after meals.
