Children all over the world are putting on weight mainly due to their sedentary lifestyle, too much fast food, too few fruits and vegetables and TV advertising that encourages children to make unhealthful food choices. In effort to make them lose weight U.S. researchers introduced a monitoring device that cut TV and computer time in half helped young, overweight children eat less and lose weight.

Leonard Epstein of the University at Buffalo, the State University of New York and his team studied 70 children aged 4 to 7 whose body mass index or BMI was at the 75th percentile or higher for their age and gender. A BMI is a ratio of height and weight. All of the children regularly watched TV or played computer games at least 14 hours per week at home.
