Jumbo portions lead to overeating: Study

Larger portions and oversized tableware do contribute to overeating, a new study reports. Eliminating jumbo servings of foods and beverages could reduce caloric intake among Americans by 29 percent, British researchers found.
"Helping people to avoid 'overserving' themselves or others with larger portions of food or drink by reducing their size, availability and appeal in shops, restaurants and in the home, is likely to be a good way of helping lots of people to reduce their risk of overeating," said the study's co-leader, Dr. Gareth Hollands, a behavior and health researcher at the University of Cambridge.
Until now, the evidence for this effect has been fragmented, so the overall picture has been unclear, Hollands said in a university news release.
"There has also been a tendency to portray personal characteristics like being overweight or a lack of self-control as the main reason people overeat," he added.  It has long been known that overeating leads to obesity, increasing your risk for serious chronic health issues, including heart disease, diabetes and cancer. The researchers analyzed the results of 61 high-quality studies involving more than 6,700 participants. The study, published Sept. 14 in the Cochrane Database of Systematic Reviews, found that people routinely offered larger portion sizes consistently ate more food and drank more non-alcoholic beverages.
This effect didn't vary much between men and women or by body mass index (a measure used to assess a healthy weight), the study authors said.
With improved portion control, daily energy consumed from food among U.S. adults would drop 22 to 29 percent (up to 527 calories a day), the investigators determined.
But new legislation and marketing tactics may be needed to help bring about significant reductions in food consumption, the study suggested.
Potential actions the study authors recommend include setting limits on the serving sizes of high-calorie foods and drinks -- such as desserts and sugary beverages -- and restricting the size of plates, bowls, utensils and glasses.
