8. Eat From a Smaller Plate
Since 1900, the size of a plate has increased from 23 to 28 centimetre. Research has shown that this caused mankind to eat around 50 extra calories every day. The Delboeuf-illusion explains why we eat more from a bigger plate: two identical circles aren’t identical when you place the one in a big and the other in a small circle. In other words: it’s an optical illusion.
It looks like you eat more from a smaller plate, which causes you to put less food on the plate in the first place. Besides, people usually feel satisfied once their plate is empty, regardless (to a certain extent) of how full or big the plate was.
