Design outcomes

Primary

MeasureTime frame
Blood pressue. Timepoint: The beginning of the study (before the start of the intervention), the end of the study (12 weeks after the start of the intervention). Method of measurement: Blood pressure will be measured at the beginning and end of the study. To do this, patients will be at complete rest for 5 minutes. After 5 minutes, blood pressure will be measured twice on the patient's right arm with an Omron digital upper arm blood pressure monitor (made in Japan) at least 30 seconds apart and the average will be recorded.;Inflammatory factor IL-6. Timepoint: The beginning of the study (before the start of the intervention), the end of the study (12 weeks after the start of the intervention). Method of measurement: ELISA test.;Glycemic indices. Timepoint: The beginning of the study (before the start of the intervention), the end of the study (12 weeks after the start of the intervention). Method of measurement: Glycemic indices including FBS and Insulin will be examined by calorimetric and quantitative luminescence methods, respectively. Insulin resistance will be calculated through HOMA-IR index according to the following formula:HOMA-IR : Fasting glucose (m mol /l)* Fasting insulin (µU/ml) / 22.5Insulin sensitivity will also be calculated in this study through QUICKI index according to the following formula:QUICKI: [log fasting glucose (mg/dL) + log fasting insulin (µU/mL)] -1.;Lipid profile. Timepoint: The beginning of the study (before the start of the intervention), the end of the study (12 weeks after the start of the intervention). Method of measurement: TG, HDL-C, and TC concentrations will be measured calorimetrically, and LDL-C concentrations will be calculated using the Friedewald formula.LDL-C (mg/dL) = TC (mg/dL) - HDL-C (mg/dL) – (TG (mg/dL)/5).;Liver enzymes. Timepoint: The beginning of the study (before the start of the intervention), the end of the study (12 weeks after the start of the intervention). Method of measurement: Measurement of liver enz

Secondary

MeasureTime frame
FLI. Timepoint: The beginning of the study (before the start of the intervention), the end of the study (12 weeks after the start of the intervention). Method of measurement: Fatty liver index predicts hepatic steatosis through calculation.
