Importance of visual cues in the control of food intake
http://www.medicalnewstoday.com/medicalnews.php?newsid=22294#"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.
