Background Obesity is a global health challenge linked to reduced physical activity, poor sleep, and increased fatigue. While diet is central to weight management, resistance training may offer additional benefits, but its combined impact on sleep and activity patterns in individuals with obesity remains unclear. This study aimed to compare the effects of a 12-week resistance training program combined with calorie-restricted dietary intervention (Diet + RT) versus diet alone on self-reported physical activity levels, sleep quality, fatigue, body weight, and waist circumference in individuals with obesity. Methods In this randomized controlled trial, 40 individuals with obesity were assigned to either a calorie-restricted Diet group or a Diet + RT group for 12 weeks. The exercise program targeted major muscle groups at moderate intensity, performed three times per week under professional supervision. Outcomes included the International Physical Activity Questionnaire (IPAQ), Pittsburgh Sleep Quality Index (PSQI), Fatigue Severity Scale (FSS), body weight, and waist circumference, measured at baseline, mid-intervention, and post-intervention. Data were analyzed using repeated-measures ANOVA and chi-square tests. Results Groups were comparable at baseline (all p > 0.05). Significant time x group interactions were found for body weight (F = 25.83), waist circumference (F = 27.38), sleep quality (F = 22.19), and fatigue severity (F = 53.94) (all p < 0.001), favoring the combined intervention. Self-reported physical activity levels, measured via the IPAQ, also differed significantly between groups at baseline (chi(2) = 8.44), mid-intervention (chi(2) = 16.41), and post-intervention (chi(2) = 14.40) (all p < 0.01). Conclusions Diet + RT yields superior improvements in self-reported physical activity, sleep quality, body weight, fatigue, and waist circumference compared to diet alone in individuals with obesity.
