For me, when my emotional state is not good, it's not about enjoying the food. It's the act of eating it. I could be eating cornstarch packing peanuts (yes, Mudpie enjoyed one of those on the weekend though I didn't try one
) or nuggets of sawdust. It's getting as much food into my mouth as fast as I can, without tasting much.
I don't do it often now and I eat waaay less than I used to during a binge but sometimes I am still triggered. Always when I am emotionally disturbed in a negative way - anxiety, anger, boredom, etc.
And sometimes it's not a binge at all but merely an item of food that is THERE. I don't really want it or enjoy it but I eat it anyway. I still haven't puzzled this behaviour out.
