The size of your dishes and eating utensils might influence how much you eat and how much you weigh, according to Cornell University researchers. Their study was based upon a simple idea-that people would take, and consume, more foods when provided with larger serving utensils and dishes than when they were given smaller ones.

To test this idea, the researchers looked at a group of 85 nutrition experts-a population with extensive education about healthy eating habits. At an ice cream social held in 2002 to celebrate the success of a colleague, the nutrition experts were given either a larger (34 oz.) or smaller (17 oz.) bowl or a larger (3 oz.) or smaller (2 oz.) ice cream scoop. The participants were allowed to serve themselves, and their ice cream portions were weighed.

Interestingly, the nutrition experts who had been given larger bowls and larger ice cream scoops served themselves substantially more ice cream than the participants with smaller utensils and bowls. Those with larger bowls took 31% more ice cream than those with smaller bowls, and those with the bigger scoops took 14% more than those with the smaller scoops.
