The weekend is finally here, and to make sure that you don't stray off your diet, we'll leave you with a new video on the science of overeating. Basically your eyes are your enemy. The evidence lies in a bottomless soup bowl experiment devised by the 2007 Ig Nobel prize winner in Nutrition, Brian Wansink. Participants in the experiment were 73 percent more likely to eat a larger portion of soup if their bowl was imperceptibly refilled as they ate, according to the research titled Bottomless Bowls: Why Visual Cues of Portion Size May Influence Intake, published in the journal Obesity. For Wansink's take on the results, check out the episode: Related Content: Newsflash: Swallowing Swords Is Bad For Your Health Discoblog: Beer Brawls and Bras at the 2009 Ig Nobel Awards Discoblog: Crunchy Chips and Smart Slime Mold Win 2008 Ig Nobel Prizes
