The color of your dinnerware can actually help you lose weight, suggests a study soon to be published in the Journal of Consumer Research. Folks who ate from plates that matched their food in color (think: pasta Alfredo on a white plate) were more likely to overserve themselves than those who ate from non-matching plates. While you’re probably not going to keep a rainbow of different-colored place settings on hand, if you’ve got a weakness for , say, mac and cheese, dish it into a bright blue bowl to help cut calories.
