Like to watch TV or play with your phone while you eat your dinner?Watch out—it could make you pile on the pounds.Not paying attention to our food makes us tend to more snacking later.
Over a series of experiments were carried out by researchers.For the first experiment,39 normal-weight young women were randomly assigned to one of three experimental conditions: a high-distraction group,a low-distraction group,and a no-distraction group.Each person was given the same 400-calorie lunch consisting of several food items presented in a fixed order,and instructed to eat all of the items.
In the high-distraction group,the women were told to play a computer game while eating,and that they would win money if they did well.In the low-distraction group they were just told to play the game while eating; and in the third group they were just told to eat their lunch.Later in the afternoon,each participant had access to a variety of biscuits on a plate,and the amount each person ate was assessed by weighing the plate before and afterwards.
There was a significant difference between the groups.Those in the high-distraction condition ate 69 per cent more snacks than the no-distraction group,and those in the low-distraction group eating 28 per cent more (than those in the no-distraction group) .
A second experiment,involving a further 63 people,was similar,but involved watching TV (in the distraction condition) and eating soup and bread.This found that those who watched TV while eating their lunch ate 19 per cent more biscuits later on than those who had eaten their meal without any distractions.
A third experiment was also carried out,in which 45 normal-weight people were allocated to three groups.The first listened to an audio clip instructing them to imagine they were watching themselves eat—making them extremely focused on their own food intake.The second listened to a clip instructing them to imagine they were watching a celebrity—specifically David Beckham—eat (making them still focused on the food,but to a lesser degree);the third,which was the control group,just ate their lunch in silence.When all participants were given access to biscuits later,those in the self-imagining group-i.e. those who had really paid attention to what they were eating—ate far fewer than the other groups.
