| 1. Anthropometric and clinical variables measured at baseline and 3 months as follows: 1.1. Weight (kg) measured using a calibrated digital scale 1.2. Height (cm) measured using a stadiometer 1.3. Body mass index (BMI, kg/m²) calculated from weight and height 1.4. Systolic and diastolic blood pressure (mmHg) measured using a validated automated sphygmomanometer 2. Serum biochemical parameters, including glucose, glycated hemoglobin (HbA1c), triglycerides, total cholesterol and HDL cholesterol (HDL-c), are measured using routine commercially available enzymatic assays (Roche Diagnostics, Basel, Switzerland), at baseline and at 3 months 3. Biomarkers of food intake (exploratory outcomes) are measured at baseline and 3 months as follows: 3.1. Hydroxytyrosol and tyrosol are measured in urine samples using liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) 3.2. a-linolenic acid and carotenoids are measured in plasma samples using liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) 4. Dietary variables are measured using the Mediterranean Diet Adherence Screener (MEDAS), a Food Frequency Questionnaire (FFQ), structured dietary records, and image-based dietary records collected via the LogMeal app, at baseline and 3 months 5. Usability of the LogMeal app measured using the LogMeal App Usability Questionnaire at baseline and 3 months 6. Sociodemographic variables: age (years) self-reported at baseline and 3 months | — |
