Fitness ads may have an unintended affect on us; they may actually make us eat more. In a recent study published in the journal Obesity 53 students where asked to study posters from an exercise campaign and on another occasion were asked to study posters that did not mention exercise. They were told they would be given a few raisins afterward; those who studied the exercise posters ate more raisins than those who studied the non-exercise posters. The lead author, Dolores Alberracin, stated that the setting of the advertisement was important. If the advertisement was more conducive to eating than exercise than the participants ate.
