Don't eat in front of TV if you want to lose weight
If you watch TV while eating lunch, you're likely to snack more later in the afternoon. Appetite psychologists discovered this when they did an experiment with sixteen female students. Watching TV increases your appetite.
Distraction increases our food intake. If you listen to music or watch TV while eating, you eat more. It seems that distraction delays the process of reaching satiety in the brain.
None of this is new, however. The British researchers wanted to know what the effect of eating-in-front-of-TV is on satiety after the meal. They wondered whether this kind of eating makes you feel hungry again more quickly, and therefore makes you more likely to snack.
After lunch – which contained four hundred kilocalories – the women were given bowls of cookies. The researchers recorded how many of these the women ate. The figure below shows that the women snacked more after a TV-lunch than after a TV-less meal.
Watching TV did not affect the way the women felt. A possible explanation of the increased consumption of snacks is that watching TV weakens one's memory of the meal. The better you can remember what you ate earlier in the day, the less likely you are to crave snacks.
Would what you watch while eating make a difference? We wonder.
Do you eat more cookies after watching a George Romero movie? Probably not...
