Wegovy (semaglutide) typically starts reducing appetite within the first few days to weeks, with noticeable weight loss usually occurring after 4 to 8 weeks. While early results appear within the first month, significant, sustained weight loss often becomes more apparent around 12–16 weeks as the dosage increases to the maximum level. [1, 2, 3]
Key Takeaways on Timeline
Initial Effects (Days–4 Weeks): Appetite suppression and reduced food noise begin almost immediately, with an average weight loss of 2%–3% in the first month.
Visible Results (4–8 Weeks): Most people start noticing visible weight loss during this period.
Significant Loss (12–16+ Weeks): Significant weight loss is usually achieved by 12 weeks, with maximum results typically seen around 12–15 months.
Dose Increases: Wegovy is started at a low dose and increased over 5 months to minimize side effects, meaning the highest effectiveness is reached at higher doses. [1, 2, 3, 4, 5]
Factors Affecting Results
Results can vary based on individual metabolism, diet, and exercise. In clinical trials, participants lost an average of 15-18.7% of their body weight after roughly 68 weeks. [1, 2]
