Home delivered diet meal service is used in weight loss diets as a result of the need for new diet-based concepts in weight management. This study was planned to evaluate some biochemical parameters, antropometric measurements and nutritional status of pre-obese and obese women who participated in weight loss program and receiveved (case=30) or not receive (control=30) home delivered diet meal service. This research; It was performed on 60 voluntary pre-obese and obese women whose body mass index (BMI) 25-35 kg/m2, between the ages of 25-45 who applied to a private instution providing healthy nutrition service in Kayseri and were scheduled for weight loss treatment. The case and control group were followed for 8 weeks. Participants’ general information, food consumption records, physical activity status, anthropometric measurements, bioelectrical impedance analysis (BIA), resting metabolic rate with ergospirometer (FITMATE) and eating behavior with the Three-Factor Eating Scale were evaluated. Some biochemical parameters (fasting blood glucose (FBG), HOMA-IR, lipid profile etc) of all individuals were recorded. Adequate and balanced nutrition plan (55-60% carbohydrate, 15-20% protein, 25-30% fat) was planed for all individuals, taking into account their general nutritional habits and healt status. Some parameters examined at the beginning (1st week) and at the end (8th week) of the study; body weight (p>0.05), body mass index (BMI) (p>0.05), waist circumference (p<0.01), hip circumference (p<0.05), body fat percentage (p>0.05), resting metabolic rate (p<0.05) values’ difference were found higher in individuals who received home delivered diet meas than in the control group. During the research process, an increase in dietary protein (p<0.001 and p<0.001, respectively) and fat (p<0.001 and p<0.001, respectively) intake and a decrease in carbohydrate (p<0.001 and p<0.001, respectively) intake were determined in case and control groups. During the study, fiber intake decreased in the case group (p<0.001) and increased in the control group (p<0.001). When evaluated in terms of groupxtime, the difference between them is statistically significant (p<0.001).While uncontrolled eating and emotional eating scores were lower in individuals who received home delivered diet meal service, conscious restraint scores were higher (p<0.05). In case group, there was a significant positive correlation between the difference in body weight loss at the beginning (1st week) and the end (8th week) of the study and waist circumference (p<0.001), hip circumference (p<0.05), serum fasting glucose (FBG) (p<0.05), serum insulin (p<0,001), HOMA-IR (p<0.01); and also negative correlation between HDL (p<0.05). In control group, there was a significant positive correlation between the difference in body weight loss and waist circumference (p<0.001), hip circumference (p<0.001), neck circumference (p<0.001), FBG (p<0.001), insulin (p<0.001), HOMA-IR (p<0.05). As a result of this study, when the groupxtime effect was evaluated, no statistically significant difference was found in terms of weight loss (p>0.05). When evaluated together with other health markers (glycemic control, lipid profile, blood pressure, etc.), it is thought that home delivered diet meal service may be a good alternative for obese individuals who cannot prepare healthy meals and cannot adapt to diet because they cannot control portion sizes.
