Unbalanced diet consumption is a major contributor to adolescent nutritional problems at international and local levels. This educational program aims to improve students' knowledge of balanced nutrition at SMP Negeri 03 Kendari. This pre-experimental study used a one-group pre-test post-test design involving 33 seventh-grade students. The intervention was delivered through interactive socialization using the educational game “Ranking 1” and the icebreaker “Guess the Picture.” Data were collected through questionnaires administered before and after the intervention. The data were analyzed descriptively and bivariately using a paired t-test, with a significance level of p < 0.05. The results showed that the average student knowledge score increased from 70.60 in the pre-test to 83.23 in the post-test (p = 0.000). These findings indicate that interactive learning can improve adolescents' understanding of balanced nutrition in the school environment. Consistent nutrition education in schools is therefore important to encourage adolescents to adopt healthier eating patterns independently and support optimal growth and development.
