It might be time to rewrite the diet books. Israeli psychologists have questioned the widely held belief that eating from small plates helps you control food portions and make you feel fuller, Scientific American
. influence the amount of food that people eat. In a 2012 study, participants who received larger bowls ended up eating more soup than those who received smaller bowls.
However, researchers at the Ben Gurion University of Negev in Israel concluded in a study published in the newspaper The Appetite that the effectiveness of the Illusion depends on how empty your stomach is. The team of scientists studied two groups of participants: one who ate three hours before the experience, and another who ate an hour before. When participants showed images of pizzas on platters of different sizes, the group that had not eaten for several hours was more accurate in badessing the size of the pizzas. In other words, the more hungry they were, the less likely they were to be deceived by the different plateaus.
However, both groups were also deluded by the illusion when asked to estimate the size of non-food items, such as as black circles in the interior white circles and hubcaps in the tires. Researchers say it demonstrates that motivational factors, such as appetite, affect how we perceive food. The findings also concur with findings from an earlier study, which found that overweight people are less likely to fall into the illusion than people of normal weight.
So go ahead and get a big plate once in a while. At the very least, this can save you a second trip to the buffet table.
