Intensive lifestyle interventions (diet and exercise) alone are insufficient to prevent significant weight regain after discontinuation of incretin-based therapy, although they may modestly attenuate the rebound.
Even if you commit to intense diet and exercise after stopping your weight loss medication, you will likely regain a significant amount of weight. Lifestyle changes are important for your health, but they are not a substitute for the medication's hormonal effects in preventing regain.
GoodQualifiesHIGH confidence
Intensive lifestyle modification can attenuate body weight rebound after withdrawal of incretin treatment, but the effect is limited and highly variable, with most individuals experiencing significant weight regain.

- 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.Strong
- Dose de-escalation (tapering) or low-dose maintenance therapy may modestly limit the rate and magnitude of weight regain compared to abrupt cessation, but robust randomized evidence is currently lacking.Moderate
