The rapid development of technology in the 4.0 era has led to a decrease in physical activity among adolescents, resulting in a sedentary lifestyle. This is characterized by adolescents spending significant time (approximately 56 hours daily) sitting or lying down while using gadgets, which reduces exercise frequency and promotes excessive fat accumulation. The prevalence of overweight and obesity in children aged 5-18 years is reported to be 19.7%. This study aimed to determine the relationship between physical activity and fast-food consumption habits with the incidence of overweight among adolescents at SMA Negeri 8 Jambi City. This quantitative, cross-sectional study was conducted from May to June 2025. The population comprised 360 adolescents, with a sample size of 78 participants selected using Proportional Random Sampling. The instruments used for data collection were the Physical Activity Level (PAL) for physical activity, the Food Frequency Questionnaire (FFQ) for fast food consumption habits, and a digital scale and microtomies for measuring overweight status. Data analysis included univariate and bivariate analyses using the Chi-Square test to examine the relationship between the independent variables (physical activity and fast-food consumption habits) and the dependent variable (incidence of overweight). The results showed that the majority of participants exhibited light physical activity (62 adolescents, 79.5%), frequent fast-food consumption (50 adolescents, 64.1%), and were overweight (47 adolescents, 60.2%). A significant relationship was found between physical activity and the incidence of overweight (p=0.021), and between fast food consumption habits and the incidence of overweight (p=0.01). It is recommended that adolescents reduce their fast-food consumption, increase their physical activity, and make it a habit to consume more vegetables and fruits to prevent overweight.
