Abstract
Recent literature highlights that the use of smartphones during meals increases the number of calories ingested in young people. Although the distraction interferes with physiological signals of hunger and satiety, a social facilitation effect has also been suggested. Cognition is a pivotal component in regulating food intake, and activities requiring high perceptual demands should be discouraged during meals.
Highlights
In recent decades, the use of smartphones has gradually increased worldwide
In the United States, cell phone access in young people has increased from 40% in 2004 to 75% in 2013 (Rideout et al, 2010, 2013), and 53% report having a smartphone from the age of 11, with an increase of more than 80% to 14 years (Anderson and Jiang, 2018; Rideout and Robb, 2019)
These results showed that smartphone use during meals, as well as reading a printed text, significantly affects the number of calories ingested
Summary
The use of smartphones has gradually increased worldwide. Currently, more than three billion people in the world own a smartphone with an expected increase in the few years of several hundred million (O’Dea, 2020). Related to owning a mobile device, teenagers report a growing increase in media multitasking activities during their ordinary daily activities: in the bathroom, in bed, on the street, and especially during mealtimes (Webby Awards, 2015). It has been highlighted that media multitasking via smartphone provides a distracting effect for tasks including reading an article and crossing the street (Stavrinos et al, 2009; Chen and Yan, 2016) Drawing on this observations, in our review, we will analyze the first experimental evidence that smartphone use, similar to other technological devices (Bellisle et al, 2004; Brunstrom and Mitchell, 2006; Hetherington et al, 2006; Robinson et al, 2013), promotes food intake by distracting users from eating behavior
