Weight Regain After Stopping GLP-1s: What the Evidence Shows
What trials such as STEP 4 show about weight regain after stopping semaglutide, and what it means for long-term GLP-1 planning.
Do you regain weight after stopping a GLP-1?
Evidence indicates many people regain a substantial portion of lost weight after stopping GLP-1 therapy. In the STEP 4 trial (JAMA, 2021), participants who switched from semaglutide to placebo regained much of their lost weight over the following year, while those who continued largely maintained it. GLP-1 therapy is generally a long-term treatment.

What STEP 4 showed
STEP 4 ran an initial semaglutide phase, then randomized participants to continue or switch to placebo. The continuation group maintained weight loss; the placebo group regained a large share, underscoring obesity as a chronic condition requiring ongoing management.
Planning for the long term
Because stopping often leads to regain, discuss a sustainable plan — including cost and continuity — with your clinician before starting. Predictable long-term pricing matters; see an independent cost comparison.
Frequently asked questions
Will I regain weight if I stop semaglutide?
Trials such as STEP 4 show substantial regain after stopping, while continued treatment maintains loss; plan for the long term with your clinician.
Is GLP-1 therapy lifelong?
It is generally a long-term treatment for a chronic condition; duration is an individual clinical decision.
