I don’t understand the mechanics of the weight coming back, like you use this, your appetite changes you eat less etc, doesn’t your body adjust to the lower caloric intake and all that.
How is it that once you stop taking everything reverts?

In response, your body secretes more hormones, so you take more GLP-1 drugs. Increase until you reach a stable balance that adequately controls the hunger.
Now, when you stop taking the GLP-1 drugs, you have a flood of surplus hunger hormones... and the hunger comes back with a vengeance. Plus, you probably haven't learned any effective coping skills for dealing with that hunger while taking the drug - so you're likely to revert to old lifestyle practices.
Or at least that's my understanding. The endocrine system is complicated. However, mechanism aside, the data is clear that people regain the weight once they stop. There's a relevant study here:
