Most everyone has heard that if you want to lose weight, you should take smaller portions, put your fork down between bites, chew slowly, etc. etc. etc.
But researchers have found that a bevy of other behaviors may cause people to gorge, especially at buffets (which, really, Congress should just outlaw until we get over this obesity crisis).
To wit, researchers found that overweight diners sat 16 feet closer to the buffet than normal weight diners. They were also more likely to face the food, use larger plates, eat with forks instead of chopsticks, and serve themselves right away instead of browsing the food.
One assumes that counseling people NOT to do these things has a shot at stopping them from eating quite so much. Perhaps something to pass along to your portly patients who are planning a trip to a buffet-laden place like Vegas. Or a cruise.
