People Who Postpone a Snack Craving Have Less Desire for It; Eat Less Over Time, Study Finds
Jan. 30, 2012 -- Got a craving for chocolate ice cream, greasy chips, or something else that you're trying not to eat?
People who postpone a snack they crave actually desire it less and are able to delay eating it, says researcher Nicole Mead, PhD, an assistant professor at Catolica-Lisbon School of Business and Economics in Portugal.
What's more, they then eat less of that food over the next week, she has found.
One key? Postponing has to be to some vague time in the future.
"When you postpone to some indefinite time in the future, the desire for the food actually decreases," Mead says. She presented her findings at the annual meeting of the Society for Personality and Social Psychology in San Diego.
Coping With Cravings
When a craving hits, people often think they have two choices, Mead says: giving in or resisting.
"If you give up, you are usually feeling guilty," she says. If you resist, you often feel deprived and ''you might overindulge later on."
"We propose a third option: To say to yourself, 'I can have it later.'"
It takes you out of that ''yes-no,'' ''should I or shouldn't I?'' conflict, she says.
Postponing vs. Not: The Studies
Mead tested the strategy using different snack foods.
In one study, she invited 99 men and women to watch film clips. She put a bowl of candies in front of each participant. The participants weren't told what the researchers were actually studying. She assigned them to one of three groups:
- One group was told they could eat the candies freely.
- Another group was asked not to eat them.
- A third group was told they could have them later.
After the film clip viewing, Mead asked the participants unrelated questions, such as whether the temperature in the room was OK, again to throw them off.
Then she told all of them it was OK to eat the candies. The participants weren't told that the researchers were going to measure how much candy they ate.
The group told not to eat the candies while watching the film ate the most, about a third of an ounce. Those told to eat freely and those asked to postpone each ate about half that amount. The postponing group ate a little less than the eat-freely group.
"We also measured chocolate consumption over one week," Mead says. The postponing group ate chocolate candy only once during the week after the experiment. The group told to eat freely ate it three times. The group told not to eat it at the film viewing ate it about four-and-a-half times.
