Primary Outcome Measures

Name	Time	Method
Change from Baseline (0 hr) in untargeted PBMC gene expression profile at 2 hr and 4 hr	Prior to the initial intervention at 0 hr and after intervention at 2 hr and 4 hr.	The venous blood samples will be taken for isolation of peripheral blood mononuclear cells. Extracted total RNA will then be used for running RNA-seq/whole-transcriptome shotgun sequencing (Illumina, San Diego, CA, USA)

Secondary Outcome Measures

Name	Time	Method
Subjective appetite ratings using standard subjective 100 mm VAS	Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min.	Appetite will be assessed using standard subjective 100 mm VAS (visual analogue scale) at time intervals throughout each visit
Metabolic biomarkers	Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min.	The capillary blood samples will be taken for blood glucose analysis. The venous blood samples will be taken for further assessment of insulin, triacylglycerol, NEFA and inflammatory biomarkers (i.e. IL-6, IL-8, CRP)
Metabolite profile	Prior to the initial intervention at 0 min and after intervention at 15, 30, 45, 60, 90, 120, 180 and 240 min.	Metabolite profile will be analyzed using Liquid Chromatography-Mass Spectrometry based methods
