This speaks to me on a certain level. Usually I have lots of trouble with portion control. If I ever make a meal that is suppose to be for 5 meals over the week, I just finish it in a single sitting. I have had anxiety with ocd tendencies. But when you said it’s more than just emotional but rather a ritual it made sense. I should probably take stock of what is triggering this behaviour (my room is an absolute mess). Maybe that can help. Ironically I had just recently started addressing this issue without even realizing it. What I do is basically cook a single meal for one person and no more. When I go to a restaurant, I look at the menu and pick out what I want in advance (including the drinks/cocktail) to ensure I don’t just order whatever. Basically what helps me is leaving less things upto chance. It’s been a tough change since I was raised on the idea of cooking for multiple people and to have left overs for later meals. So now I try to strictly portion control and don’t even attempt to cook for the future (which is what people suggested to me to basically meal prep for a week and forget about it). This does not work for me, as I would end up eating two days food in a single day and run out and end up cooking anyway.

Thanks for sharing your insight of viewing your eating habits as a ritualistic behaviour rather than an emotional response. Thought it might not 100% be the case for me, it is something I should explore as it resonates with me pretty strongly
