than the blue circle on the left. Actually, this is an illusion when something is surrounded

by large objects it looks relatively small - take away the surrounding objects and you

can see that the blue circles are actually the same size. This simple illusion affects

your waistline. When you place a portion of food on a small plate it looks relatively

large and so you end up putting less on the plate. In fact, psychologist Brian Wansink

has discovered that just moving from a 12-inch to a 10-inch plate causes people to eat about

20% less. So if you want to lose weight the easy way, simply switch to smaller plates.
