Use smaller plates.

".....Bigger plates mean bigger portions. And that means you eat more. According to a study conducted by Wansink and his research team, if you made a simple change and served your dinner on 10-inch plates instead of a 12-inch plate, you would eat 22% less food over the course of the next year.
On a related note, if you’re thinking “I’ll just put less food on my plate” … it’s not that simple. The picture below explains why. When you eat a small portion off of a large plate, your mind feels unsatisfied. Meanwhile, the same portion will feel more filling when eaten off of a small plate. The circles in the image below are the same size, but your brain (and stomach) doesn’t view them that way...."
