In the above video, it is shown how the size of the bowl, plate, or spoon that you use can significantly influence how much food and how many calories you consume. In the study Ice cream illusions: bowls, spoons, and self-served portion sizes, 85 nutrition experts at an ice cream social were randomly given either a smaller (17 oz) or a larger (34 oz) bowl and either a smaller (2 oz) or larger (3 oz) ice cream scoop. After serving themselves, they completed a brief survey as their ice cream was weighed. The researchers found that when nutrition experts were given a larger bowl, they served themselves 31% more without being aware of it. In addition, their servings increased by over 14% when they were given a larger serving spoon.
In a study from the University of Pennsylvania, psychologists conducted an experiment in an upscale apartment building in which they left out a bowl of chocolate candies with a small scoop. The next day they refilled the bowl with M&M's, but left out a much larger scoop. When the scoop size was increased, people took 66 percent more M&M's!
The conclusion: use smaller plates, bowls and utensils, even if somebody laughs at you for eating your soup with a teaspoon.
