Scientists say that dieters should take a small plate to a buffet, and then look at everything being offered before choosing what they want.
A recent study found that skinny people are more likely to scout out the food and look at the different alternatives before they pounce on something.
However, heavy people just tend to pick up a plate and look at each item and say, "Do I want it? Yes or no."
Slim diners are seven times more likely to take a small plate than larger people are, and larger people sit about 16 feet closer to the buffet than thin people and chew their food for less time.
