The study involved the 3 day recall of both diet and media use among 473 individuals.
Plainly, researchers found that meals that were consumed along with some form of media distraction contained 149 more calories. They also found that people consuming those extra calories at a media meal did not compensate by eating less at their next meal.
Given how easy it is to do this, and how by doing so you might even strengthen some interpersonal relationships by eating with friends or family around a table, you really have almost nothing to lose by trying, except perhaps a few calories.
