‘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.

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,
