Outcome Measures

Primary Outcomes (10)

  • Change in body weight

    Body weight (kg) was measured using the InBody 270 brand device.

    Baseline, 8 weeks

  • Change in body mass indexs

    The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m\^2, resulting from mass in kilograms and height in metres.

    Baseline, 8 weeks

  • Change in fat mass measured by bioelectrical impedance analyzer

    Fat mass (kg) was measured using the InBody 270 brand device.

    Baseline, 8 weeks

  • Change in fat-free mass measured by bioelectrical impedance analyzer

    Fat-free mass (kg) was measured using the InBody 270 brand device.

    Baseline, 8 weeks

  • Change in resting metabolic rate (RMR) measured by bioelectrical impedance analyzer

    RMR (kcal) was measured using the InBody 270 brand device.

    Baseline, 8 weeks

  • Change in interleukin 6 (IL-6)

    Blood was drawn from participants for assessment of IL-6 (pg/mL) at the beginning and end of the study after fasting for at least 8 hours

    Baseline, 8 weeks

  • Change in tumor necrosis factor alpha (TNF-α)

    Blood was drawn from participants for assessment of TNF-α (pg/mL) at the beginning and end of the study after fasting for at least 8 hours

    Baseline, 8 weeks

  • Change in malondialdehyde (MDA)

    Blood was drawn from participants for assessment of MDA (mmol/L) at the beginning and end of the study after fasting for at least 8 hours

    Baseline, 8 weeks

  • Change in total antioxidant status (TAS)

    Blood was drawn from participants for assessment of TAS (mmol/L) at the beginning and end of the study after fasting for at least 8 hours

    Baseline, 8 weeks

  • Change in total oxidant status (TOS)

    Blood was drawn from participants for assessment of TOS (µmol/L) at the beginning and end of the study after fasting for at least 8 hours

    Baseline, 8 weeks

Secondary Outcomes (4)

  • Change in waist circumference

    Baseline, 8 weeks

  • Change in hip circumference

    Baseline, 8 weeks

  • Change in dietary inflammatory index (DII)

    Baseline, 8 weeks

  • Change in oxidative stress index (OSI)

    Baseline, 8 weeks

Study Arms (1)

Mediterranean Diet

EXPERIMENTAL

In the study, the participants were applied a diet compatible with the Mediterranean diet for 8 weeks.

Behavioral: Mediterranean Diet

Interventions

While calculating the energy of the Mediterranean diet applied to the individuals participating in the study, Mifflin-St. Jeor equation is used. The macronutrient composition of the Mediterranean diet was calculated as 36-40% fat, 40-45% carbohydrate and 15-20% protein. This diet is enriched with natural foods (fruits, vegetables, legumes, whole grain foods, fish, olive oil and oilseeds such as walnuts and almonds). In addition, anthropometric measurements and body composition analysis of the participants were performed both at the beginning and at the end of the study, and some biochemical parameters (IL-6, TNF-α, CRP, MDA, TAS, TOS and routine blood parameters) were evaluated.
