Design outcomes

Primary

MeasureTime frame
Measured using blood test: 1. Haptoglobin gene polymorphism genotype (fixed outcome), serum CD136, and serum haptoglobin were determined at baseline 2. Serum CD136, and serum haptoglobin levels were measured after four-week consecutive intermittent fasting

Secondary

MeasureTime frame
Measured at baseline, and after four weeks intermittent fasting: 1. Body weight (kg), BMI (kg/m²) 2. Inflammatory (IL-6, TNF-alpha, IL-10) and metabolic markers (lipid profile, glucose homeostasis) measured using blood test
