Center of Doom

My daughter fasting in Bible College for a weekend, I think. I honestly couldn't tell you what she was studying at that point. What I understood from her was that she had fluids all planned out thus freeing her thoughts from anticipating food or it's preparation. Something along the lines of taking your mind off the corporate for it to be more fully involved in your thoughts ??? I didn't put that very well but perhaps you know what I mean.
She honestly felt that God protected her from the munchies and stomach growling hunger. She neither lost nor gained weight.
