Background/Objectives: Low physical activity (PA) is becoming an increasingly serious health problem among overweight school-age children. This study aimed to evaluate the influence of elevated PA during school hours on the nutritional behavior and fat mass of overweight and obese children. Methods: The study involved 11-year-old children (n = 148) who were overweight and obese. In the control group, children received physical education lessons in the standard dimension (4 h a week) while the intervention group received 10 h. Body mass index (BMI), fat mass (FM), and nutritional behavior were analyzed. Results: Compared to baseline, at the end of the intervention, the proportion of obese children increased in the control group and decreased in the intervention group. Regarding nutritional behavior, low consumption of vegetables, fruits, whole grains, poultry, and fish was observed. After a 12-month period, the intervention group showed a slight decrease in the consumption of fruits, vegetables, cold cuts, fried dishes, sweets, and fast food, and an increase in the consumption of white bread, whole-grain bread, poultry, red meat, and dairy products (milk, yogurt). In the control group, children exhibited an average increase in the consumption of fruits, vegetables, poultry, red meat, sweets, and fast food Conclusions: Although extended physical activity during school hours was correlated with a decrease in the number of obese children, the observational nature of the study precludes the drawing of definitive conclusions. The intervention may have contributed to an increase in energy expenditure, which could account for the improvements in BMI and FM. Nevertheless, the impact on nutritional behavior was limited.
