Same thing with intermittent fasting. One deviation and the appetite comes back with a vengeance and you have to restart from scratch the process of getting used to fasting (which is the hard part, the appetite is what makes the caveman go out chase the mammoth, it's a strong force).

Experimenting with Mounjaro right now + intermittent fasting. So far so good, but only one week into it. I am hoping to use it as a guardrail in case of any accidental deviation.
