Researchers at the University of Illinois at Urbana-Champaign report dramatic evidence of the importance of visual cues in the control of food intake in the current issue of Obesity Research, a leading nutrition journal.



The researchers served a free soup lunch to 54 adults, half of whom ate from normal 18-ounce soup bowls, while the other half ate from identical bowls that, unbeknownst to the participants, were slowly refilled through tubing connected to out-of-sight soup cauldrons.

Those who ate out of the refilling bowls consumed 73 percent more soup than did participants who ate from the normal soup bowl during the 20-minute lunch.


Although they averaged 113 more calories than those eating from normal bowls, those eating from the bottomless bowls believed they consumed the same number of calories as the other participants and rated themselves as being no more full.

"People use their eyes to count calories and not their stomachs," lead researcher Brian Wansink, professor of marketing and of nutritional science at Illinois, said. "This can be dangerous to our diets."

Because we appear to judge our food intake by visual cues, such as an empty bowl, Wansink said that people worried about overeating should carefully consider the size of portion servings in restaurants and in their kitchens.

He suggested, for example, repackaging snacks and other bulk foods into small plastic bags. The visual cues from the filled bags can lead families, especially children, to think that a smaller-than-normal serving was a satisfying full serving.

The paper, titled "Bottomless Bowls: Why Visual Cues of Portion Size May Influence Intake," was co-written by James E. Painter, a professor of family and consumer science at Eastern Illinois University, and Jill North, a graduate student in food science and human nutrition at Illinois.

Im Focus: Why we need erasable MRI scans

New technology could allow an MRI contrast agent to 'blink off,' helping doctors diagnose disease

Magnetic resonance imaging, or MRI, is a widely used medical tool for taking pictures of the insides of our body. One way to make MRI scans easier to read is...

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
