In 2023, the prevalence of malnutrition among adolescents in Indonesia was 7.6% for thin and severely thin, 12.1% overweight, and 4.1% obese. In East Java, adolescent overweight prevalence reached 13.3%, exceeding the national rate. In Malang Regency, the Health Office reported in 2022 that 19.7% of male and 32.9% of female adolescents were obese. This issue of imbalanced nutritional status is also found at SMK Plus Almaarif, due to the absence of a healthy school canteen and students’ low level of understanding regarding balanced nutrition.
