I have gone the fairly extreme route of more or less completely banning myself from eating any high calorie / highly rewarding / high glycemic index foods. And kept on that for 3 1/2 years, and lost 80kg.
In my case every previous diet got messed up by extreme hunger that I could not override, that occurred an hour or 2 after eating even small amounts of that type of food, so some sort of hormonal or neurochemical stuff up in response to what I guess are blood sugar spikes and dips. I then found it extremely hard to stop. My current diet is specifically designed to prevent those spikes and dips as much as possible.
I would guess whether indulging occasionally in high calorie foods is an issue or not depends on if you have binge eating disorder or food addiction, ( which is very common in people with obesity ) and if so your prior ability to control eating amounts and for how long when eating rich food. If controlling your eating was an issue, it might be much harder to do that after losing a lot of weight. Post weight loss, I found that extreme hunger response to be amplified to very high levels.
If you did not have those types of eating issues then indulging sometimes is not likely to be a problem.
GLP drugs definitely reduce hunger and cravings for rich food, so if you are experiencing increased hunger or cravings it might be a sign that increasing the dose might be required. Assuming no problematic side effects and doses not at maximum.
But eliminating cravings entirely is not realistic, even tirz15mg/reta5mg/cagri0.5mg does not get rid of them for me but does make overall hunger much more reasonable and a lot less cravings for unhealthy food.
