Background: Obesity is a major risk factor for many diseases. In Persian Medicine, much emphasis has been put on the balanced weight that maintains health. Therefore, the treatment of obesity is a top priority for health care in Persian and Classical Medicine. Objective: To compare the efficacy of therapeutic packages in Persian Medicine with Classical Medicine in overweight treatment. Methods: This randomized clinical trial was conducted at Ghaem Hospital in Mashhad, Iran, from August 22, 2016 to December 20, 2016. Sixty-nine overweight women with body mass index (BMI) of 27-29.9 and waist circumference more than 88 cm based on inclusion and exclusion criteria, were included in the study. To control bias in sampling, with considering that the age variable is an interventional factor in the process of effective treatment, in addition to using the random allocation method, the population were studied in three groups of 18-30 years old, 31-50 years old and >50 years old, who were classified by blocking method, and three types of treatment interventions were performed in each age group: Group A (Classical diet and orlistat), Group B (Persian diet and MDB) and Group C (classical diet and MDB). Calorie consumption was equivalent in the three groups. Blinding was done only for patients. The treatment period was three months in all three groups. Subsequently, we analyzed the effectiveness of the therapeutic packages on anthropometric index, body composition and laboratory parameters in the three groups. The data were analyzed using SPSS version 16. We used descriptive statistics, Kolmogorov-Smirnov, ANOVA, paired-samples t-test, non-parametric Wilcoxon test and regression methods for the analyses of primary and secondary outcomes.
