Smaller Portions Help You Eat Less - as part of the news series by GeoBeats.

It is believed that increases in portion size are directly related to eating more, but if the same portion is separated into smaller pieces, people and animals tend to consume less.
A study done by researchers at Arizona State University has shown food split into smaller portions is more filling and gives a greater sense of satisfaction than one bigger piece of food with equal caloric value.

The study involved testing rats and college students to see how the subjects felt and reacted when given the same food, presented in different ways. It showed that the rats ran faster for the pile of ten pellets than they did for one pellet with the same caloric value. As for the college students, they were given a bagel; some subjects were given bagels that were cut into smaller pieces and some were given whole bagels. The students were then presented with another meal twenty minutes later. The students who were given the bagel in small pieces ate less of the second meal than the subjects who ate the bagel whole, which shows that portions do factor into how much we eat.
