　　If you’re concerned about gaining weight over the upcoming holiday season，consider eating more slowly and you might consume less，a study suggests.Diet experts have been promoting this advice for years，and now nutrition scientists at the University of Rhode Island have some new data to back it up.

　　They had 30 normal-weight，college-age women come into a laboratory for lunch on two separate occasions.Each time the women were offered a huge plate of tomato-vegetable sauce plus a glass of water.They were asked to eat until the point of comfortable fullness.On one

　　occasion，they

　　were

　　instructed

　　to eat as quickly as they could；on the other occasion，they ate slowly and put down their spoons between bites.

　　They didn’t know the food and water was weighed before and after the meal to determine the amount consumed.Findings：When eating quickly，the women consumed 646 calories in about nine minutes.When eating more slowly，they had an average of 579 calories in about 29 minutes.

　　“They ate 67 calories more in nine minutes than they did in 29 minutes，”says lead researcher Kathleen Melans.“If you add that up over three meals a day，that’s a big difference in calories.”

　　Upon completion of the meal and an hour afterward，the women were less satisfied and hungrier when eating quickly compared with when they ate slowly，she says.They said they enjoyed the meal more when they were taking their time.Not surprisingly，the women drank more water when they ate more slowly，and researchers are doing a follow-up study on whether that factor contributed to their feeling of fullness.
