How to keep the weight off after done with glp1?

I got a trial dosage and unfortunately will not be able to afford them once I am off. I have lost 20 lbs and prob will lose a little more before I’m done with the microdosing.

How do I keep the weight from coming back? Obviously eat healthy and stuff like that but any other hacks or things you did that helped keep it away?

I’m more worried about the food noise. My brain has never been so quiet and I’m adhd as well.
