According to Deng et al. (2022), liraglutide and semaglutide therapies have led to weight reductions ranging from 48.2% to 88.7%. These figures emphasize liraglutide and semaglutide clinically significant weight loss in obese or overweight adults without diabetes.
Semaglutide and liraglutide fall into the category of glucagon-like peptide-1 (GLP-1) receptor agonists, which play a crucial role in appetite regulation. These hormones effectively assist individuals dealing with obesity or overweight by promoting weight loss. Notably, Wegovy and Saxenda incorporate these GLP-1 receptor agonists and have undergone rigorous testing to ensure their safety and efficacy in weight loss management.

Mechanism of Action
Wegovy and Saxenda offer prescription weight loss medication for individuals seeking solutions for their obesity or overweight concerns. Due to glucagon-like peptide-1 (GLP-1) receptor agonists as their active ingredients in these injectables, Wegovy and Saxenda have a similar mechanism of action.
GLP-1 receptor agonists are naturally occurring hormones that play a crucial role in regulating appetite and glucose levels. These medications mimic the effects of GLP-1 receptor agonists, activating increased insulin secretion and delayed gastric emptying. These injectable treatments improve blood sugar control and reduce appetite, contributing to significant weight loss.
- Wegovy’s Influence on Appetite and Metabolism: Wegovy contains semaglutide, which targets appetite regulation. Activating GLP-1 receptors in the brain reduces hunger and promotes satiety. The once-weekly injection of Wegovy provides sustained effects, making it a practical option for long-term weight management. It also has an additional impact on lowering blood sugar levels.
- Saxenda’s Influence on Appetite and Metabolism: Saxenda utilizes liraglutide, which decreases appetite and increases feelings of fullness. This injectable can also slow stomach emptying, aiding in controlling meal size and calorie intake. Its daily injection requires consistent use to maximize the benefits.
Clinical Efficacy
These injectables have undergone thorough and numerous clinical trials to prove their safety and efficacy in addressing weight-related concerns. Understanding these results can help medical professionals compare Wegovy vs Saxenda to patients seeking a better solution for their condition.
Wegovy’s FDA approval highlights the injectable’s proven safety and efficacy in promoting weight loss. According to the Prescribing Information, after 68 weeks of treatment, Wegovy demonstrated a statistically significant reduction in body weight compared to the placebo group.
Notably, a higher proportion of patients treated with Wegovy achieved weight loss milestones of 5%, 10%, and 15% compared to placebo patients. Another 68-week trial had shown that the administration of 2.4 mg of semaglutide once weekly, combined with lifestyle intervention, led to a sustained and clinically significant reduction in body weight.
On the other hand, Saxenda underwent clinical testing and was validated in a study involving 3,731 adult patients. This resulted in 85% of individuals taking the liraglutide injectable experienced weight loss. It’s worth noting that individuals lost an average of approximately 12 lbs from the start of the study.
An evidence review emphasizes that liraglutide aids in initiating and maintaining weight loss in obese patients. Its effectiveness is on par with other available treatments, but it uniquely provides the benefit of improved glycemic control. Notably, Saxenda has also received its FDA approval for chronic weight management.
