I have been a non breakfast eater for years. I am just not hungry in the mornings. I have noticed the same thing, when I eat breakfast my stomach "wakes" up and demands some food. -- Lately though, since starting Fast 5:2 plan, I have been eating 2 hard boiled eggs each morning. -- I still get the hunger pains at lunch time on fast days, but so far I have been able to ignore them.
