This trial aimed to assess the effects of high protein (HP) (45% carbohydrate, 25% protein, and 30% fat) and balanced diets (BD) (55% carbohydrate, 15% protein, and 30% fat) on weight loss and plasma adiponectin levels in overweight and obese women who do aerobic activity. A parallel double blinded randomized clinical trial. Demographic data were collected at baseline. Body weight and adiponectin levels were measured at the baseline and after eight weeks of intervention. We used SPSS software for data analyzing and Nutritionist IV for analyzing dietary intakes. The study was an eight-week trial that consisted of 56 women with BMI ≥ 25kg/m², aged 20-46 years who were randomly assigned to intervention. Body weight with adherence to HP and BD diets decreased significantly, however; the reduction in the HP group was more than the BD group (P<0.001 in both groups). Adiponectin significantly increased in HP and BD (P=0.001 and p<0.001 respectively). These changes did not significantly differ between the two groups. In conclusion, our trial showed that high protein and balanced diets resulted in desirable effects on body weight and on circulating adiponectin during the eight weeks.
