A March 2020 study by the University of Illinois found a significant decrease in the amount of food eaten whilst using technology. They said,
"It's fairly simple but distracting enough that you have to really be watching [the game] to make sure that you don't miss a number and are mentally keeping track."
"That was a big question for us going into this - how do you ensure that the participant is distracted? And [the game] was a good solution for that."
"It really seemed to matter whether they were in that distracted eating group first … Something about being distracted on their initial visit really seemed to change the amount they consumed during the nondistracted meal. There may be a potent carryover effect between the mechanism of distraction and the novelty of the food served.”
