Brief Summary

Background : Obesity prevalence rises among adults and leads to morbidity and mortality due to subsequent inflammation pathway activation. This activation is induced by higher lipid consumption which activates the Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) pathway and alters the microbiota profile. The Oryza sativa extract contains anthocyanin which possibly affects the microbiota composition and NF-kb pathway which eventually preserves the protective layer and tight junction of the epithelial cells. Therefore it is important to address the impact of this extract on these parameters. Objective : To assess the effect of Oryza sativa extract on microbiota profile (Lactobacillus, Firmicutes, Bacteroides, Bifidobacteria, and Escherichia coli), Lipopolysaccharide/ LPS, and the tight epithelial junction (Zonula Occludens-1) among obese adults. Method: A two-arm Quasi-Experimental will be conducted, followed by two repeated measurements, at the baseline and 3 weeks after intervention Hypothesis: Oryza sativa extract lowers the LPS level, Firmicutes sp, Bacteroides sp, and increases ZO1 protein, Bifidobacteria, and Lactobacillus sp.
