In other words, larger plates can cause us to eat more and smaller plates can help us eat less. Larger dishes can make portion sizes appear smaller, and smaller plates can lead us to believe that the same quantity of food is more than it actually is. Wansink and van Ittersum found that the effect applies to the plates and bowls we use. Delboeuf found that when you look at two identical circles, they are seen differently, depending on the size of the circle placed around them. These findings are part of an optical illusion known as the Delboeuf illusion, named after a Belgian scientist who discovered it in 1865. In addition, reducing the color contrast between dishes and the table, tablecloth, or placement helped reduce over-serving by as much as 10 percent.
