What is Saxenda?

Saxenda is a prescription medication that was first used as a diabetes management medication. It is a brand name for liraglutide, a GLP-1 receptor agonist and synthetic analog of the naturally occurring hormone GLP-1 (glucagon-like peptide-1). Other GLP-1 agonists include Ozempic and Wegovy. 

Saxenda was first developed as a treatment for type 2 diabetes under the name Victoza. It helps regulate blood sugar levels by mimicking the action of GLP-1. The small intestine releases this hormone in response to food intake and stimulates insulin secretion, which lowers blood glucose levels. It also suppresses the glucagon secretion, which tends to raise blood sugar.

Patients using Victoza for diabetes treatment began to report another beneficial side effect: weight loss. This unexpected discovery prompted further research, and Saxenda, with its higher dose of liraglutide, was developed and approved specifically for weight loss.¹

How Does Saxenda Work for Weight Loss?

Saxenda has several mechanisms that support weight loss. Understanding its mechanism of action is key to appreciating its effectiveness in helping individuals shed unwanted pounds.

GLP-1 and Saxenda have an appetite-suppressing effect. They act on the brain to reduce feelings of hunger, leading to decreased food intake. This reduction in calorie consumption results in weight loss.

Saxenda also slows digestion by delaying stomach emptying, which has a dual benefit. It slows the absorption of glucose from food, helping to keep blood sugar levels steady, and it contributes to a sense of fullness, further reducing the desire to eat.

Some individuals using Saxenda have reported changes in food preferences, particularly a decreased desire for high-calorie and high-fat foods.

Saxenda has demonstrated notable effectiveness in promoting weight loss as part of a comprehensive body weight management program. Clinical trials have shown that, on average, individuals using Saxenda can achieve significant weight loss compared to those receiving a placebo.^2,3

Saxenda is approved for use in adults with a body mass index (BMI) of 30 or greater or for those with a BMI of 27 or greater who have at least one weight-related medical condition, such as hypertension (high blood pressure), type 2 diabetes, or high cholesterol. Its primary purpose is to promote weight loss when used in conjunction with lifestyle changes, including a reduced-calorie diet and increased physical activity.⁴

The amount of weight lost can vary from person to person. The effectiveness of Saxenda is often influenced by factors such as adherence to a reduced-calorie diet and increased physical activity, as well as metabolic health and lifestyle. However, for many, Saxenda has proven to be a valuable tool in achieving and maintaining a healthier weight.
