Study Points To Portions For Weight Loss, But What’s Missing?

Filed under: Study — @ July 27, 2006

Cornell University food consumer researcher Brian Wansink conducted an experiment with 85 food and nutrition experts by inviting them to an ice cream social and randomly distributing one of two sizes of bowls (17-ounce or 34-ounce) and one of two sizes of serving scoops (2-ounce or 3-ounce).

The results of his study found that the people with the larger bowls got nearly one-third more ice cream than the smaller bowl group and the larger scoops generated 14.5 percent more ice cream than the smaller scoops.

Of course, Wansink and the press are using this study as an argument in favor of portion control for weight loss, but there’s a serious flaw in Wansink’s research that cuts to the heart of one of the most instinctive human behaviors.
