A study in the International Journal of Obesity found that eating a high-fat diet may cause the palate to fail to recognize fat-rich items, which may in turn alter a person's eating habits. "The response to fat is important because fat is a very potent initiator of our satiety or fullness mechanisms. If you don't have something telling you that you are full or it is time to stop eating ... you are going to keep eating more or initiate another eating event sooner," lead researcher Russell Keast said.
