The One Bowl Philosophy

Years ago I went on this diet where everything you ate had to fit inside of one bowl, and you had to eat it with your hands. It was actually a very simple way of curtailing how much you eat and realizing you don't need more than a bowlful for a meal. The whole act of eating became so simplistic, eating became consequential to living. Anyone out there ever try this? I wish I had the book on it again.
