Dawn Phenomenom in the Afternoon?

According to my nurse I should eat little and often. My old habit of having my lunch as my main meal and then possibly nothing else is unacceptable to her. She says I definitely must not leave it more than 5 or 6 hours.

Since our conversation I have never thought of it as the dawn phenomenon. It is more of a fasting phenomenon and can happen at any time of the day if you don't eat.

I suppose it got called the dawn phenomenon because most of us don't eat much overnight.
