I went for a few months recently just pushing my breakfast forward as far as I could. It seemed at first I could push it as far as 1pm or even 2pm once or twice. Gradually I could push it only to 11, then 10, then 9, then 8:30. Now I'm back to eating breakfast before I head off to work.
Other "protocols" I've been able to do are the "oh my, I ate too much last night so I won't eat until I'm truly hungry again" protocol. I'll go out for a big hike to make sure I am really hungry before I eat.
