Thinking about food can make you less hungry?

I was flipping channels yesterday and came across CBS talking about a new study being done at Carnegie Mellon, by researcher Carey Morewedge, about thinking about your food. The hypothesis is that if you concentrate on eating your food and every part of the process of consuming that food item (smell, taste, texture) that it would make you have less of a craving to eat said food.
