The results from GLP-1 weight loss therapy can begin to show within a few weeks of starting treatment, though noticeable changes may take several months. In clinical trials, individuals typically start to see a reduction in appetite and improvements in satiety within the first month of using the therapy. As the therapy suppresses hunger and slows gastric emptying, it becomes easier to stick to a reduced-calorie diet, leading to gradual weight loss. However, significant weight loss, such as the loss of 5-10% of body weight, is often achieved after 12 to 16 weeks of consistent use.

It is important to note that the rate of weight loss can vary depending on individual factors such as metabolism, adherence to dietary changes, and the level of physical activity. Some individuals may experience more rapid weight loss, while others may see slower, steady progress. GLP-1 weight loss therapy is most effective when used as part of a comprehensive weight loss plan that includes healthy eating and regular exercise. Continued use and adherence to the prescribed regimen are key to achieving and maintaining the desired results over time.
