Background: Frequent junk food consumption, characterized by high calorie, sugar, fat, and salt content with limited nutritional value, may increase the risk of overweight and unhealthy eating habits among adolescents. Nutrition education using attractive visual media, such as flipcharts, may improve adolescents’ understanding and attitudes toward healthier food choices. Objective: This study aimed to determine the effect of nutrition counseling using flipchart media on knowledge and attitudes regarding junk food among overweight adolescents at SMP Muhammadiyah Palangka Raya. Methods: A pre-experimental one-group pretest-posttest design was employed. The population consisted of overweight students in grades 7, 8, and 9. A total of 31 respondents were selected through purposive sampling. Nutrition counseling was delivered using flipchart media, while respondents’ knowledge and attitudes were assessed before and after the intervention. Differences between pretest and posttest scores were analyzed using the Wilcoxon signed-rank test. Results: Before counseling, 45.2% of respondents had poor knowledge regarding junk food. After counseling, 90.3% demonstrated good knowledge. Attitudes also improved: 74.2% of respondents had negative attitudes at pretest, whereas 71.0% demonstrated positive attitudes at posttest. Statistical analysis showed a significant difference in knowledge and attitudes before and after the intervention (p=0.001). Conclusion: Nutrition counseling using flipchart media significantly improved the knowledge and attitudes of overweight adolescents regarding junk food. Flipcharts can serve as an effective educational medium to help adolescents understand the health effects of junk food, limit its consumption, and make more informed and healthier dietary choices. This medium is practical, engaging, and suitable for school-based nutrition education
