Back in 2007, a group of researchers compared the amount of food consumed between two groups. They were curious to discover if the evidence of food already eaten (in this case, individuals were given chicken wings to eat while watching a football game) would impact the amount they ate altogether. They found that the participants ate less at the tables where the bones were left out in plain sight in comparison to the tables where the bones were removed. “The results suggest that people restrict their consumption when evidence of food consumed is available to signal how much food they have eaten.” (Brian Wansink, Cornell Chronicle, April 9, 2007).
