The effects of chronic fat overconsumption on intestinal physiology and lipid metabolism
remain elusive. It is unknown whether a fat-mediated adaptation to lipid absorption takes
place. To address this issue, mice fed a high-fat diet (40%, w/w) were refed or not a control
diet (3%, w/w) for 3 additive weeks. Despite daily lipid intake 7.7-fold higher than in controls,
fecal lipid output remained unchanged in mice fed the triglyceride (TG)-rich diet. In situ
isolated jejunal loops revealed greater [1-14 C] linoleic acid uptake without TG accumulation …
