High-fat diets induce gut barrier defects and metabolic endotoxemia (elevated LPS), which triggers low-grade inflammation and compromises insulin sensitivity.
Reducing chronic high-fat intake can help maintain gut barrier integrity, preventing the leakage of inflammatory bacterial components (LPS) into the bloodstream, which may improve insulin sensitivity.
ModerateSupportsMEDIUM confidence
These studies documented that chronic high-fat diet (HFD) consumption induces defects in the intestinal barrier, which allow the migration of intestinal contents—such as food antigens, bacteria and bacterial by-products—into the systemic circulation, with bacterial lipopolysaccharide (LPS) being a key component.

- Dietary interventions that modulate gut microbiota composition (specifically increasing SCFA-producing bacteria and reducing dysbiosis) improve metabolic health outcomes including insulin sensitivity and glucose tolerance.Moderate
- Dysbiosis (specifically reduced SCFA-producing bacteria and increased pro-inflammatory taxa) contributes to the pathogenesis of Type 2 Diabetes through mechanisms involving gut permeability, LPS-driven inflammation, and impaired insulin signaling.Moderate
