Food drive is a thing in humans too, and it's something that's largely genetic -- and it's something that you can modify with anorectic drugs like GLP-1 RAs and stimulants. How much you eat is a combination of intrinsic food drive and trait conscientiousness.

Everyone knows someone who will eat like 3 potato chips and move onto something else, while others will sit and mow down the whole bag. Taking a GLP-1 will basically just convert you from one kind to the other in a dose-dependent way.

The same kind of variability is present in dogs - but without the conscientiousness axis.
