There are a few things here. Developing willpower is a thing. Having depression or other mental health issue is another. It is easy to dismiss it as lack of willpower, but it is a bit more complicated.

I also don't think you understand how living with kcal deficiency works on the long run. Have a look at the Minnesota starvation experiment. When in deficit for long the mind constantly goes to "what/when are we going to eat?" and it only gets worse from there. It becomes an obsession. It takes over everything. My understanding is that glp-1 reduces that.

It also helps for people who have too much extra weight, or incapable (waiting for hip replacement, or the elderly) of exercising.

I have been on diet and managed to go back to the target weight (lost around ~16% of bodyweight) but the food noise was real and constant. It is not a one off "I am not going to eat anymore" that was a decision to be made every minute until next meal came around. I do cycle 10-12 hour a week and the occasional footbal game but finding the deficit that is not causing the food noise is different for everyone.
