According to statistics, almost 50% of all of us eat with the television on, and many even do it alone. This trend grows even more with the use of the smartphone. We simply eat distracted. And eating distracted is not a good idea if we want to stay in line.
In fact, eating while watching television means that, on average, people eat 15% more food than if they have the television turned off .
Depends on the program
Having the television on is bad nutritionally, but it also depends on the program we are watching, as explained by Charles Spence in his book Gastrophysics :
For example, in Australia, Dick Stevenson and his colleagues found that women who watched an episode of Friends a second time ate significantly more food than those who watched different episodes of the same series.
In short, the more sensory signals associated with food that we consciously perceive, the less we will eat.
