If you painstakingly contemplate eating the food you're about to dig into, there's a good chance you'll eat less of it. Karen Hopkin reports

��Tis the season when many of us go on a seafood diet: we see food and we eat it. But if you want to avoid packing on the pounds, a new study suggests that you should spend more time thinking about food. Because the more of a thing you imagine eating, the less you��ll actually eat.

Common sense suggests that daydream eating is not the best idea. Once you picture a piece of pecan pie, chances are you��ll go out and get some. But what if you did more than give the pie or cookie or candy a passing thought? What if you mentally ate your fill?

To find out, scientists had people imagine eating M&Ms. Thirty-three of them. One after another. They asked a second group to imagine an activity that was equally repetitive, but less filling: pumping 33 quarters into a clothes dryer. Then they put out a bowl of M&Ms.

Sure enough, people who��d already maxed out on M&Ms in their mind ate fewer than the folks who��d been doing their mental laundry. The results appear in the journal Science. [Carey Morewedge, Young Eun Huh and Joachim Vosgerau,"Thought for Food: Imagined Consumption Reduces Actual Consumption"]

So when visions of Haagen-Daz dance through your head, don��t think twice. Just pull up an imaginary spoon. And don��t skimp on the fantasy hot fudge.
