The study published this month in Obesity observed 53 college students as they looked at posters from an exercise campaign and later looked at posters that did not mention exercise. The participants were given a handful of raisins after each session. And after looking at the exercise posters they ate one-third more than they did after looking at nonfitness picsan average of 18 calories, compared with only 12.
Similar results were found with a second test, in which different students played a computer game involving either action words like "active" and "go" or neutral words like "pear" and "moon." Those who heard the action words ate more peanut M&Ms afterward than the neutral group.
Where and when these ads appear is also an important factor, says Dolores Albarracin, the study's lead author and a professor of psychology at the University of Illinois. "When the setting of the advertising is more conducive to eating than exercise, people eat," she told The New York Times last week. "If you just wallpaper everyplace with these kinds of posters, it may not do much good."
I admit, when I'm really being good about working out every day, I tend to allow myself a few (hundred) extra caloriesespecially in the form of desserts, drinks, or other "rewards" for making it to the gym. So maybe that's what subconsciously happened to the people in this study. They thought about exercising and decided to indulge a bit more in return.
But this makes me wonder about the age-old practice of using motivational photos or objectssuch as hanging up a bikini, a pair of skinny jeans, or a picture of a celebrity role modelas an inspiration to lose weight or get in shape. I recently replaced that old half-marathon ad with the brand new Team in Training jersey that I'll wear for my first triathlon in July. Now, whenever I spot it in my bedroom, I'll try to be aware of any mysterious hunger cravings!
Have you ever used fitness-related props like these as a gentle reminder of your goals? Have they worked? And do you think we need to watch out for absent-minded eating?
