Of course this is an optical illusion. And, of course, the black circles are the same size.
But how can this illusion help you lose as much as 18 pounds?
Studies by professor Brian Wansink at the Cornell Food and Brand Lab show we tend to to serve ourselves in proportion to the plate size we’re given.
And because of the Delboeuf illusion(illustrated above), an appropriate serving of food that should be filling looks like it’s not enough for you when it’s served on a larger plate.
So, you naturally eat more.
Reducing plate size from 12 inches to 10 inches typically resulted in 22% fewer calories served.
[Note, however, that once plate size dropped below 9.5 inches “people begin to realize they’re tricking themselves and go back for seconds and thirds.” – Wansink]
The study predicted that using a 10 inch plate for a year would lead to a weight loss of 18 pounds for the average adult.
Simple, huh?
Give it a shot and let me know how you do.
