What food makes rat livers fatty?
Dietary fat stimulates development of NAFLD more potently than dietary fructose in Sprague–Dawley rats

Surprising Findings
Fructose didn’t cause significant liver fat buildup in rats, despite being widely blamed for fatty liver disease.
Public health messaging often singles out fructose (from soda, processed foods) as the main villain in NAFLD. This study shows fat is far more potent in driving liver fat accumulation — at least in rats.
Practical Takeaways
Limit processed foods high in both saturated fat and cholesterol (like fast food, fried items, processed meats) to protect your liver.

Eating too many carbs and calories — especially from sugary or processed foods — is what mainly causes fatty liver, not eating fat. Cutting out carbs or going on a carnivore diet might help reverse it.
Feeding rats a diet super high in fat leads to fat building up in their livers after 16 weeks — kind of like what happens in fatty liver disease. Scientists saw this through lab tests, scans, and looking at liver tissue under a microscope.
Feeding rats a diet super high in fructose for 4 months doesn’t really hurt their liver overall, even though a few tiny signs of fat buildup show up under a microscope.
In lab rats, eating a diet high in fat, sugar, and cholesterol causes worse liver damage than just eating a high-fat diet — with more signs of inflammation and scarring in the liver.
In lab rats, eating a diet super high in fructose (like from sugary foods) makes their blood fat levels skyrocket—way more than other unhealthy diets—and this seems to mess up how their body handles fat overall, not just hurt the liver.
