personally i had to start listening to the dialog in my head and be counter to it. for years i woudl tell myself i was not hungry. after 11 months of following a new protocol i realize that i am still doing that , just so fast i dont see/hear it. so just this week i decided that if the thought came thru my head " you are not hungry" that meant i was.
I eat until i no longer feel jittery or stomach stops growling.
for me it is a very sensitive state
