- Primary Outcome Measures
Name Time Method Endothelial function. This will be measured by using a SphygmoCor system.[At baseline and at 12 weeks after intervention commencement];Inflammatory markers. Plasma high-sensitivity C-reactive protein (Hs-CRP) will be measured by using a Cobas Mira Plus Analyser. Plasma intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) will be measured by using Quantikine enzyme-linked immunosorbent assay (ELISA) Kits.[At baseline and at 6 and 12 weeks after intervention commencement];Plasma lipids and lipoproteins. Plasma total cholesterol, high density lipoprotein cholesterol (HDL-C) and triglyceride concentrations will be measured by enzymatic methods using a Cobas Mira Plus analyser. Plasma low density lipoprotein cholesterol (LDL-C) concentration will be calculated using the Friedewald formula.[At baseline and at 6 and 12 weeks after intervention commencement]
- Secondary Outcome Measures
Name Time Method Body composition. This will be measured by using a bioelectrical impedance analysis.[At baseline and at 6 and 12 weeks after intervention commencement];Oral fatty acid sensitivity. This will be determined via triplicate sensory evaluations (triangle tests).[At baseline and at 12 weeks after intervention commencement]
