In the study (subscription required), 10 overweight and 10 normal weight women participated in the study; each was randomly assigned to dine with either an 8.5-inch or a 10.8-inch dinner plate. Told to eat until they felt satisfied, the women were studied over one meal (lunch) on two different days and each used a different-sized plate every time they ate.
The plate size did not affect the amount of calories that participants ate at either meal. However, overweight/obese women in the study reported feeling less hungry prior to the meal and less full afterward.
Reading the results, I’m left wondering whether a longer study would have told a different story or if more direction about what to eat would have made a difference. But you can read more about the study in this HealthDay News story.
