Method of measurement: Immunoturbidometric method.;Apolipoprotein B. Timepoint: The beginning of the study (before the start of intervention), the end of the study (8 weeks after the start of the intervention). Method of measurement: Immunoturbidometric method.;Inflammatory factor IL-6. Timepoint: The beginning of the study (before the start of intervention), the end of the study (8 weeks after the start of the intervention). Method of measurement: ELISA test.;MDA. Timepoint: The beginning of the study (before the start of intervention), the end of the study (8 weeks after the start of the intervention). Method of measurement: ELISA test.;Lipid profile. Timepoint: The beginning of the study (before the start of intervention), the end of the study (8 weeks after the start of the intervention).
