I’m approaching this as a “stupid brain won’t do what I want” situation as I used to eat the double portion also. My work around was to cook out of sync to what I ate. This meant I didn’t need to worry about what I was eating “now” because everything I cooked was for later. So as an example, I would cook some chilli, but that day I would be eating some curry that was already sitting in the fridge. If you are wondering how to start the cycle, the simplest solution to avoid your cravings messing it up is to cook and then order takeout somewhere so you don’t eat it any of it.

It could be that the improvising is getting in the way. Does this mean you don’t know what to cook until you do?
