Primary Metabolic Goal

Why SCFA Optimization Triggers GLP-1

When gut bacteria ferment specific soluble fibers (like inulin and resistant starch), they produce Short-Chain Fatty Acids (SCFAs)—predominantly acetate, propionate, and butyrate. These metabolites bind to Free Fatty Acid Receptors (FFAR2 and FFAR3) on colonic L-cells, causing direct, calcium-dependent secretion of endogenous GLP-1 into portal circulation.
