Children, Obesity, Television announcements, and Infrastructure

I am seeking to study the effect of lifestyle on obese children. From my previous work, Nutrition field is one that expected to solve many problems in future, so we shall look at the physical, biochemical and psychological aspects of eating and lifestyle. As a biochemist, I understand the relation and biochemical interaction between foods, and its metabolites that reacted with the human body. But, what about the procedure that brings foods to our body, what about the psychological, environmental interaction with our body. I realized that we first should look to the cause before we deal with symptoms, who is responsible for children obesity, who target the psychology of our dear children, the answer is television advertisements? Television announcement is trying to make you enjoy by buying and eating. You don't need to eat something to feel happy. Some opinions can agree with me and others will not. Should, we prevent our children from watching TV anymore, or that is not the solution. Kids should get used to both the positive and the negative viewpoints of our society from an early age. The book for whom is motivating in children obesity, nutrition, and psychology.
