Hi OP! I'm also addicted to food, as it sounds like you are. Not the funnest addiction lol! What has been working for me, albeit slowly, is starting with triggering "times" of the day. For instance a lot of my empty calories come in the evening after DD is in bed. Now I go to the gym during that time or craft (funny I always complained I never had time to do that, but had plenty of time to stuff food in my face...).
Once that was done I focused on one meal at a time. I had to cut out sweets 100%. For me it's honestly like telling an alcoholic to have a sip of wine/beer/vodka once a day. One sip/bite is going to lead to a LOT more. If I don't allow myself any of it, I don't slip.
Now I hope at some point I will be able to do it, but looking at the past 35 years I rather doubt it
