Brian Wansink from Cornell observed 213 randomly-selected patrons of 11 all-you-can-eat Chinese buffets across the United States. Heavier patrons were more likely to: Face the buffet while eating. Begin serving themselves immediately instead of surveying the buffet. Pick up a larger plate vs. a smaller one. Use a fork instead of chopsticks. Leave less food leftover on their plate and Chew fewer times per bite. Find the original article here: http://the-f-word.org/blogfiles/ChineseBuffetStudy.pdf
