Using a smaller plate does not reduce calorie intake according to a study from researchers at Pennsylvania State University in University Park, Pennsylvania, USA. Plate Sizes
Plate size of 6.7 inches or 8.7 inches or 10 inches did not change calorie intake
People who ate from plates that were 6.7 inches, 8.7 inches or 10 inches ate the same amount of food within 34 calories.
Subjects and conditions
Subjects and conditions: 3 studies to determine the results
Three studies were conducted to determine these results.
Study 1: Three plate sizes
In the first study, 45 people were given plates that were 6.7 inches, 8.7 inches or 10 inches and served the main course from a large dish. Calorie intake was similar regardless of the plate size.
Study 2: Served an equal amount of food on either the 8.7 inch plate or 10 inch plate
In the second study, 30 people received an equal amount of food on the 8.7 inch plate and on the 10 inch plate. They ate a simlar amount of food regardless of the plate size.
Study 3: Ate at buffett with different plate sizes
In the third study, 44 people used each of the three plates and selected from five foods from a buffett which were all had a similar amount of calories per quantity of food. The people ate a similar amount of food regardless of the plate that they were using. When using the smallest plate, they simply went back to the buffett more times than when they were using the larger plates.
Conclusion: Smaller plates do not change calorie intake
This is somewhat of a surprise because some researchers have suggested that putting food on smaller plates should help to reduce calorie intake, however, this study found that this was not the case.
“These findings show that using a smaller plate did not lead to a reduction in food intake at meals eaten in the laboratory,” the researchers concluded.
