Well, why you emotionally eat, solve whatever problem the emotion is pointing to and just leave the food out of the equation? I will be reading something and be triggered and suddenly find myself in front of the refrigerator. I put a book in there and that reminded me to think back to what I was thinking before I got up. I go re-read the passage and feel whatever it is and work on that instead of getting something to eat. There's nothing saying you cannot reward yourself with a carrot versus a cookie is there?

I use to do something with that, too, when I would read too much and chew off all my fingernails unconsciously. So, I got a stick of cinnamon and chewed on that instead. I'm sure my intestines did not thank me (splinters :-) but if I'm going to chew, I guess I'd rather it was something other than my fingernails, don't care what?

There's a lot of symbols and allegory there; gnashing of teeth, chewing someone out, so hungry I could eat a horse, dreams of teeth (falling out, especially) and they're related to emotions rather than actual eating.

Play a game where you have to do something "silly" if you catch yourself trying to emotionally eat. Or, overeat something "safe" (have you ever eaten a pound or two of grapes in one sitting?) and suffer the actual consequences and use that as a reminder of what is happening to you but unbeknownst to you (gaining weight doesn't have those immediate consequences).
