Upon further research....
I really think this is the root cause of my binge eating disorder.

I notice I never 'binge' on typical "comfort foods" like chocolate, nutella etc but actually foods heavy in gluten and casein! Annndd it is usually triggered by a physical pain response. My cravings for stuff like Greek yogurt (not normal yogurt), quark cheese, French bread, pizza, phillidelphia and such is always when my back is in significant pain. Whenever it gets manipulated by a physio and it doesn't hurt the cravings stop regardless of calorie deficit or not.

Perhaps my brain is craving the opiate activities of these products to dull the chronic pain? I do notice that hwhen my diet is high inbthese products my pain tolerance is very high
