New research from Rice University indicates that mindless switching between digital devices is associated with increased susceptibility to food temptations and lack of self-control, which may result in weight gain.

"Increased exposure to phones, tablets and other portable devices has been one of the most significant changes to our environments in the past few decades, and this occurred during a period in which obesity rates also climbed in many places," said Richard Lopez, a postdoctoral research fellow at Rice and the study's lead author. "So, we wanted to conduct this research to determine whether links exists between obesity and abuse of digital devices -- as captured by people's tendency to engage in media multitasking."
