We aimed to advance mechanistic understanding of lean NAFLD using guinea pigs fed a western diet (WD) during postnatal growing phase. Methods: Normally in utero grown guinea pig offspring were randomly assigned to receive ad libitum a control (CD) diet or WD (high fat/high sugar + 0.25% cholesterol) from weaning to postnatal day (PND) 150 (young adulthood). In vivo computed tomography (CT, ~ PDN 120), organ weight determinations and hepatic histology analyses (150 PDN) were undertaken. Hepatic differentially expressed genes (DEGs) were identified using the GeneChip™ Guinea Pig Gene 1.1 ST Array Plate and TAC software (-22, FRD p-value
