I'm no expert, but I reckon you should probably talk to your mental health professional about your plan BEFORE you start following it. They may help you gain some insights into whether aspects of it are dangerous to you. And I think meditation, or other healthy outlets for your emotions are going to be massively important, because taking away the numbing effect of overeating might expose you to some uncomfortable emotions. You need to take care of that as you go along, and not wait till you reach a crisis.
