Primary | Changes to the gut microbiota | The primary objective of this study is to determine the effect of a synbiotic formulation called ProSynbiotic (administered at 3 capsules/day) containing 4 billion CFU of a probiotic blend of Bifidobacterium lactis BB-12, Lactobacillus acidophilus LA-5, Lactobacillus casei 431 and Saccharomyces boulardii, along with 1 g of the prebiotic inulin and 100 mg of galactooligosaccharide (GOS) on the gut microbiota of healthy overweight adult subjects when compared to a placebo of maltodextrin. Changes in the gut microbiota will be determined by measuring specific bacterial population levels in the subjects' fecal samples, using 16S rRNA targeted oligonucleotide probes and fluorescence in situ hybridisation. | 0-weeks (Baseline), 6-weeks (midpoint of intervention), 12-weeks (end of intervention) and 16-weeks (4-weeks after end of intervention) | No |
Secondary | Body composition | The effect of Prosynbiotic on the subjects' body composition will be evaluated by BOD POD assessment carried out at baseline, 6-weeks and 12-weeks. | Baseline, 6-weeks and 12-weeks. | No |
Secondary | Expression of genes mediating dietary energy harvest and adiposity | This will be achieved by measuring the gene expression levels of ANGPTL4, PPAR-? and GPR41/43 in colonocytes isolated from stool and that of ANGPTL4, PPAR-?, NF-kB, IL-6 and TNF-a in PBMCs isolated from blood collected from the subjects at baseline and 12-weeks. | Baseline and 12-weeks | No |
Secondary | Adiposity-related metabolic markers | This will be achieved by measuring TNF-a, adiponectin, total cholesterol, LDL-C, HDL-C, triglycerides and glucose levels in fasting blood samples collected from the study subjects at baseline and 12-weeks. | Baseline and 12-weeks | No |
