If you are in ketosis you cannot have "true" hunger... however, I learned while doing LL to listen to my body -- if I was feeling hungry, then I was instructed to sit down and take out my journal and "explore" my feeelings. I realised pretty quickly that when I was upset, angry, stressed -- that I mistaked those feelings for hunger. And, don't get me wrong... I felt HUNGRY. But, if I did something to destress, deal with anger, etc. then the hunger disappeared.
