In this study, eating lunch in front of the computer led to negative outcomes. Subjects again ate more later in the day.
"Distracted individuals were less full after lunch, and they ate significantly more biscuits in the taste test than did nondistracted participants."
"These findings provide further evidence that distraction during one meal has the capacity to influence subsequent eating. They may also help to explain the well-documented association between sedentary screen-time activities and overweight."
