When I have that feeling, it usually means I've had a BE spike of some sort. For instance, I used to feel that way all day the day after drinking. No matter what I ate, I still felt hollow and hungry. I will get it mildly after something like going to a concert and staying up much later than normal. It all made sense after Kathleen explained that we have BE receptors in our digestive system. Now that I know it's not physical hunger, I can ride it out. I eat a little bit of extra fat and that helps too. But I don't know if that is what you are experiencing or not.
