A group of Doctors, scientists and researchers conducted a two-year study of overweight and obese adolescent children (12 and 13 years old). The group tried to to modify dietary behavior by incorporating a web-based computer-tailored intervention program. The program aimed to increase physical activity, decrease sedentary behavior, and promote healthy eating among adolescents. The "FATaintPHAT" study did not produce the desired positive long-term outcome researchers were hoping for. However, there were positive short-term effects on eating behaviors, according to the report published online by Archives of Pediatrics & Adolescent Medicine and on the JAMA/Archives journals.
