I don’t think this is healthy. I have a similar experience when writing where my body/brain just doesn’t want to work anymore - however instead of eating, I go for a run with music that has a fast tempo and a lot of bass. I think my brain just likes a change and the exercise + music is an activity I like. Maybe your brain is just looking for some novelty to break up the monotony of work. It doesn’t have to be food, it could be something else - but should be something that you enjoy. While indulging in fave foods sometimes is not a problem - regular binge eating may have some negative health consequences later down the track so if you can mix it up, and maybe not do it as a weekly thing that would probably be good for your overall health and wellbeing
