It’s no different from people who undergo gastric bypass surgery. Those with food addictions/habits manifest them elsewhere such as gambling, or if they are seriously addicted, they continue to eat which bursts their band.
My wife is back devouring cookies after being on mounjaro for 4 months. Thankfully she lost most weight all by herself so wasn’t totally reliant on the medication. But it’s crazy how noticeable the difference of one’s eating habits when on and off it.
