Exclusion criteria were: pregnancy, lactation, patients with chronic diseases as arthritis, CVD, T2DM, hypothyroidism, hypertension, and intake of drugs that can affect weight e.g. corticosteroids, anti-depressive medications and insulin. A convenient sample was chosen for selection of enrolled participants, mainly from Taibah University as well as, graduated students in addition to students’ relatives and friends. The questionnaire concerned with demographic data, family history of obesity, physical activity level, and the age of introduction of olive oil in the dietary pattern was filled by face to face interview. Anthropometric measurements were obtained by trained team based on a standardized procedure. Using the World Health Organization (WHO) criteria to define BMI categories (WHO, 1999). A BMI result of less than 18.5kg/m2 is considered underweight, 18.5-24.9 kg/m2 is normal, 25-29.9kg/m2 is overweight, while 30kg/m2 and above is obese. Waist circumference was measured using flexible measuring tape. The Waist circumference cut-offs based on ethnic specific values for European, Sub-Saharan African, Eastern Mediterranean and Middle Eastern (Arab) which is >94 centimeters for men and >80 centimeters for women. Standardized methods were used for measurements. The weight was measured using electronic weight scale, while the height was measured using a stadiometer. Regarding Waist circumference measure, participants were asked to stand with back straight. Heavy clothing was removed from the waist line. The tape was aligned at the top of the hip bone (iliac crest) parallel with the edge of the last palpable rib (nearly 2 centimeters above the navel). The waist measure was taken at the end of a normal expiration and approximated to the nearest 0.5 cm. In accordance to WC definition, exclusion was done for obese and underweight participants (WHO, 2008). Detailed 24-hours recall were taken for two days and the mean level was calculated.
