Summary

This trial compares different ways to help people manage their weight after they stop taking certain medications. They will measure the weight change after 12 weeks to see which treatment works best.

Who is the study for?
This trial is for individuals who have been using semaglutide or tirzepatide for obesity but are stopping these medications. Participants should be adults looking to manage their weight post-discontinuation.
What is being tested?
The study examines three treatments: a combination of Bupropion-Naltrexone-Metformin, just Bupropion-Naltrexone, and a Weight Watchers Clinic program. The goal is to see which helps maintain or reduce weight after stopping GLP-1 meds over 12 weeks.
What are the potential side effects?
Possible side effects may include nausea, headaches, constipation from the medication combinations, and potential mood changes due to Bupropion. The WW Clinic program may not have direct medical side effects.
