No full reta trials exist yet, so the closest data comes from tirzepatide work like SURMOUNT-4, which points to reduced results if you stop and later restart.
I know many think these meds are lifelong, but suppose someone wants to stop eventually. I began at 420 pounds, dropped to 240, and held that for a year and a half by eating well without pushing further loss. Now that I am on reta, I wonder how others handle coming off once they hit their target.
