A nutrition expert who was not involved in the study praised the research, but questioned whether these strategies might really be powerful enough help.
"As with all of Wansink's observations, these are insightful and useful," said Dr. David Katz, director of the Yale University Prevention Research Center, in New Haven, Conn. "But in some ways, they are like looking for the reasons why some people got wet sooner than others when the Titanic went down. The bigger issue was: The ship was sinking, and everyone was in the same boat."
Katz said the best advice for dieters might be to avoid a buffet's temptations in the first place. "By all means, survey the scene and choose a small plate," he said. "But, better yet, avoid the all-you-can-eat buffet altogether."
