Background. Weight loss among teenagers who are overweight and obese is an issue that is gaining more attention in Malaysia. Although short-term weight loss interventions have shown positive results, their long-term effectiveness is still debated. Objectives. This study aims to evaluate the effects of the ECNYB program, which combines balanced nutrition and physical activity, on weight loss over 8 weeks. Methods. This quasi-experimental study involved 40 students randomly assigned into two groups: the treatment group, which followed the ECNYB program, and the control group, which only continued their usual Physical and Health Education (PHE) classes. Data were analyzed using descriptive and inferential statistics, focusing on weight, height, and Body Mass Index (BMI) changes. Results. The results showed a significant weight reduction in the treatment group (M = 33.8 kg, SD = 4.2 in the first term, M = 31.1 kg, SD = 3.9 in the second term), while the control group did not show significant changes. A paired sample t-test confirmed significant differences between the treatment and control groups. Conclusion. This study suggests that the ECNYB intervention could have positive short-term effects, and further studies are recommended to extend the intervention to 12 weeks to evaluate its long-term effects. © 2025, Society of Aging and Physical Activity (SAPA).
