I typically go from 1900-2000 (dinner) to 1200 (lunch) the next day. Everyone is different, and then there's the fact that this is daily habit training. I start getting hungry around 1100 and 1800, because ¡surprise!, I typically eat about an hour later. I have no doubt that if I started eating breakfast when I woke up, I'd probably wake up hungry also. EDIT: I should also point out that I trained myself to fast during college. One day a week I wouldn't eat at all. Now, when I get hungry, the feeling will last for a little bit then go away.
