hunger panic

Hi I have been working on overeating for almost 2 years now, still when I am low on the hunger scale my primitive brain panics, tells me I am going to die and my higher brain finds impossible to judge my bodily sensation (the hunger,emptiness, dizziness, restlessness) as neutral. Could you remind me some thoughts I could practice in the moment to move beyond the fear? I remember Brooke speaking about it many times but I have a hard time finding back those resources, maybe you could also point me at them, thanks
