Fig. 4 — Pleiotropic effects of short chain fatty acids (SCFAs). Short chain fatty acids (SCFAs) have potent systemic effects which involve several organs and complex pathways referred to metabolic homeostasis. Main SCFAs are products of microbiome-dependent digestion from dietary fibers. Thus, qualitative, and quantitative qualitative shift in microbial diversity can derange several pathways at different levels, i.e., adipose tissue, immune cells, liver, pancreas, intestine, and brain involving gluco-lipid-inflammatory changes and food intake. **Abbreviations**: GLP-1, glucagon-like peptide-1; GLUT-4, activated glucose transporter protein-4; GPR, G-protein-coupled receptors; IL, interleukin; PYY; peptide YY; TNFa, tumor necrosis factor alpha; (+), increase; (-), decrease.
