Did you know that participants in the SURMOUNT-1 trial lost up to 20% of their body weight using Tirzepatide?
How quickly does tirzepatide work for weight loss? But before answering this, let us discuss what is Tirzepatide, Tirzepatide —marketed as Mounjaro for type 2 diabetes and emerging as a promising option for weight management—is a dual GIP and GLP-1 receptor agonist. How quickly does Tirzepatide work for weight loss? By mimicking incretin hormones, it enhances insulin secretion, regulates blood sugar, and suppresses appetite.
Although approved by the FDA for type 2 diabetes, its significant off-label weight loss benefits have captured the attention of healthcare professionals and patients alike.
(Note: The “up to 20%” figure represents the maximum weight loss observed in some participants under optimal conditions in the SURMOUNT-1 trial.)
Mechanism of Action
Tirzepatide works by:
- Activating GIP and GLP-1 receptors: Boosts insulin secretion and lowers glucagon levels.
- Delaying gastric emptying: Helps reduce hunger and control caloric intake.
This dual action not only improves glycemic control but also supports significant weight loss over time.
Weight Loss Timeline & Summary
The table below summarizes key weight loss milestones, with data derived from the SURMOUNT-1 trial:
| Phase | Expected Weight Loss % | Timeline |
| Initial Phase | Up to 5% reduction | Weeks 1-4 |
| Intermediate Phase | 5-10% reduction | Months 1-3 |
| Long-Term Phase | 15-20% reduction | Beyond 3 months |
