The responsibility shall be taken by us first. The blame is on us. Children are not obese because they like to eat fast food. Our lifestyle habits have made them weaker and lazier by day. The society entertains the idea of going out and eat stuff which is not only delicious but also fast to cook and ready to eat.
Children should be encouraged to drink juices and eat green vegetables more. This is the only difference between children of today and children of past. Families knew that children should play outside and take part in social activities than just sitting in front of the computer like most of them do today.
