There's A Name For It - Volumetrics

I have been a proponent of eating high volume, low calorie density foods as a means of losing weight. I had thought it was called volumizing, but recently heard it referred to as "volumetrics" and on seaching the term, quickly found that that seems to be the term that's used. It appears that Penn State is the research center leading this concept. I can say that from my experience, it works at letting you lose weight without hunger.
