Your TV can make you pack on the pounds! Wondering how? A team of researchers seem to have the answer.
While watching television is a good time pass, it can play havoc on your waistline, say a group of researchers, who claim that food advertisements have a powerful influence on its viewers, especially university students.
"The transition from adolescence to adulthood has been shown to be a time for taking on many negative health behaviors including increases in smoking and alcohol use and decreases in physical activity and fruit and vegetable consumption," said Kim Raine, director of the University of Alberta's Center for Health Promotion Studies.
What the researchers found was quite alarming.
University students who reported medium or high television viewership snacked more frequently while watching TV and recognized more advertising than students who were considered low TV viewers.
The students who watched over four hours or more of TV per day snacked more frequently while watching TV, recognized more TV advertisements and consumed more energy-dense snacks than students who viewed less than one hour of TV per day.
Specifically, male students and medium-to-high television viewers had higher odds of being overweight or obese.
"The link between how much a person snacks while watching TV was directly related to viewing food advertisements, specifically when choosing to eat an energy-dense snack," said John Spence, co-author of the study and U of A professor in the Faculty of Physical Education and Recreation.
"The exposure to the advertising seems to stimulate a desire to eat that particular food product. Also, sitting watching TV provides a prime opportunity to snack," he added.
The study has been published in the American Journal of Health Promotion.
