NEW YORK --One new bit of research claims you might eat less if you use a white plate.Research says using a white plate allows a person to see the amount of food a person is getting. ABC News' chief health and medical editor Dr. Richard Besser put the theory to the test at a restaurant in New York City. "It turns out people with the red plates took an average of two ounces more of pasta than people with white plates," said Besser. "That might not sound like a lot, but that can add up over time." Besser said two ounces of the pasta was equal to 200 calories or two extra pounds over the course of a month. Besser said the key is contrast, so white plates work well. The worst choices are red and gold plates, according to Besser, since those colors blend in with a lot of food.
