BLOOD
We conducted a single-center, randomized, and double-blind clinical trial. Participants, researchers, and statisticians were blinded. All subjects were initially randomly assigned by simple randomization procedures (computerized random numbers) to the intervention group (Patients in Furthermore, the validated Persian language version [Venous blood samples were collected after 12 to 14 h of overnight fasting before and after 12 weeks of intervention. The serum samples for measuring FBS and hs-CRP were frozen at -80 ˚C until measurement. Systolic and diastolic blood pressure were recorded after rest (at least 5 min), in the sitting position, using an OMRON M6 Comfort Automatic Blood Pressure Monitor (Tokyo, Japan) at baseline and after 12 weeks of study. Participants' weight and height were measured by using a standard calibrated scale (Seca, Hamburg, Germany) and Waist circumference (WC) were assessed by a practiced researcher. Body mass index (BMI) was calculated according to the following equation BMI = weight (kg)/length2 (m2).
