King, prince, and pauper

I heard a skinny holistic health person talking about the concept of the king, prince, and pauper in regard to weight loss and meals.  Breakfast is supposed to be the king, the biggest meal of the day.  Lunch (the prince) is smaller, and you should barely eat any supper at all.  Sarah actually does that; Noah does the complete opposite. He usually skips breakfast, eats a huge lunch, and a gigantic supper.  So yesterday I explained the king, prince, and pauper principle to him.  This morning, I was loading the crockpot with food for supper, and Noah said, "Looks like the pauper is having dinner with the king tonight!"
