The size of your plate can determine how much food you actually eat. This was the finding of a study published in the Journal of the Academy of Nutrition and Dietetics.
The study suggests that the size of the dishes used for food serves as a reference in choosing the quantity of food eaten. The larger the dish size, the more likely a person is to put more food on the plate.
This means that using a smaller plate might just be what a person who wants to eat less should consider.
