It might seem evident that sitting in front of the boob tube can turn you into a couch potato, but with all the commercials centered on junk food, the results are even more staggering. According to a study by some University of Liverpool researchers, TV ads about food increased the amount of food eaten by already obese children by 134 percent. A study of 60 kids between 9 and 11 years of age found that overweight children ate 101 percent more (and normal weight children, 84 percent more) after being shown a series of TV food and toy ads, in between a cartoon. When the watching period was over, children were provided with a variety of foods, and obese children consistently selected chocolate and jelly-filled sweets. The researchers also have plans to study whether or not public responsiveness to kids watching too much TV can actually avert childhood obesity.
