While it is obvious that inactivity, diet, and genetics play a role in obesity, the actual number one factor found is alarming. The number one cause they found contributing to the rapid rise of obesity among children was social influences- commercials, media influences, and advertising.
It seems that advertisers are doing more and more research and getting smarter and smarter about how to entice viewers and markets to buy their flavorful fattening foods and products. Essentially, what happens is a food company's board of advertisers conducts intensive research as to what flavors are irresistible to the palette, as well as what phrases and slogans stimulate the most craving for their product. This powerful combination influences the children to want to eat those foods that are full of sugar, fat, but plenty of flavor.
While it doesn't help that inactivity, or sedentary lifestyles, have also increased, the number one factor was the potency of commercial advertising and its' effect and influence over the mind that persuades kids to have to want to eat their foods. In other words, one of the best counters to preventing and diminishing childhood obesity would be to educate them on the harmful effects of such foods, as well as the reason behind the advertising and how it is meant to convince them to want to have the unhealthy food, even though it is not good for them. In the same way parents and teachers have spent efforts to teach kids to say no to drugs, which are sold by drug dealers, they should now begin to teach kids to say no to sugary foods and fattening foods, which are sold by corporate junk food dealers.
