<![CDATA[Obesity is a health problem that can occur in various circles, including adolescents. The prevalence of obesity in adolescents continues to increase, although various efforts have been made to prevent and control obesity. Health education with the lecture method is less effective to be applied to today's youth.

Nutrition education began with giving a pretest, then continued with the provision of material containing indicators of obesity, causes, impacts and how to prevent obesity with animated video media, to see the increase in knowledge, students were given posttest and discussion and question and answer.
