Evaluation of the effects of diet and exercise on body weight loss, body composition, anthropometric measurements and biochemical parameters in adult obese women.

This is a prospective cohort study, conducted on adult women, aged between 20-45 years, living in Adana, during 3 months in the years of 2009-2010. The overweight and obese participants were seperated into two groups according to body mass index (BMI) >27 kg/m². While the first group (n:20) had performed weight loss diet therapy alone, the second group (n:18) had performed weight loss diet therapy and exercise. The weight loss of the participants in the diet + exercise group and diet grup has decreased 86,91±12,70 kg to 79,80±12,80 kg; and 87,26±21,60 kg to 80,79±22,32 kg respectively. Significant differences within the groups on body weight (kg), body fat mass (kg) and body fat percentage (%) were found (p<0,01). Decreases in hip circumference measurements were statistically different between the two groups(p<0,01). Hip circumference measurement decreased 7,15 cm in the diet + exercise group and 4,94 cm on diet group. Significant changes in blood pressure levels also were determined in individuals of both groups (p<0,05). Triiodotironin hormon (T3) and albumin values in biochemical results between the two groups showed a significant differences(p<0,05). Results of this study showed that, a well planned weight loss diet application have positive effects on weight loss, body composition and measurements of body circumference in both of the groups. Moreover exercise is more effective on decreases of hip circumference and systolic blood pressure.
