A plateau on a GLP-1 is not failure — weight loss on these drugs typically happens in the first year and then levels off, and trials show exactly this pattern. Before assuming the drug 'stopped working', check the food-side levers: protein still at target, portions creeping back up, or snacking filling the gap.
Weight loss slows as the body adjusts; appetite suppression can fade slightly over time; eating habits can quietly drift back. Plateaus are expected in the long-term curve.
The steep early loss (fluid and initial appetite change) gives way to a slower curve — this is the normal pattern in trials. Check the food side: protein still 1.2-1.6 g/kg, portions not creeping, no liquid calories. Then it is a conversation with your provider about the plan.
No — plateaus are part of the expected curve. The drug's metabolic and appetite effects continue; the weight curve simply levels off. Your provider can review whether the dose or plan needs adjustment.
Re-tighten the food basics: protein targets, fiber, water, and honest portions. Increase daily activity. And keep the long view — the plateau is where maintenance habits get built.
Rapid weight regain during a plateau, or plateau with concerning symptoms — discuss with your healthcare provider.
