Participants were divided into two groups: the control group received health education only, while the observation group received additional dietary and exercise interventions. Pre- and post-intervention changes in anthropometric indicators, body fat levels, lipid profiles, inflammatory markers, physical activity levels, and parental satisfaction were assessed.Results: Baseline characteristics were similar between groups (P > 0.05). After intervention, the observation group showed significantly lower body weight, BMI, waist-to-hip ratio, body fat percentage, visceral fat area, and lipid levels (TG, TC, LDL-C), along with higher basal metabolic rate (P < 0.05). Physical activity increased and sedentary time decreased significantly in the observation group (P < 0.001). Additionally, inflammatory markers (IL-6, IL-8, TNF-α) were markedly reduced in the observation group (P < 0.05), and parental satisfaction was significantly higher compared to the control group.Conclusion: A combined dietary and exercise intervention significantly improves body composition, lipid metabolism, physical activity levels, and inflammatory status in obese children. This comprehensive model may be an effective, non-pharmacological strategy for promoting healthy growth and managing childhood obesity.Keywords: obese children, combined diet and exercise intervention, physical measurements, blood lipid levels
