Hormonal

Discontinuation of incretin-based therapies (GLP-1/GIP agonists) consistently leads to rapid and clinically meaningful weight regain, typically recovering two-thirds of lost weight within one year, alongside the reversal of cardiometabolic improvements.

If you stop taking incretin-based weight loss medication, you will likely regain about two-thirds of the weight you lost within a year. This is not a failure of willpower but a biological response to the loss of the drug's hormonal effects. To maintain your weight loss, you likely need to continue the medication long-term or use very aggressive, sustained lifestyle interventions, though even those are often insufficient to prevent significant regain.
