Objective: Our objective was to create a pragmatic model of NAFLD/NASH. METHODS Sprague-Dawley rats were fed a high-fat, high sugar homemade diet ad libitum for seven weeks. The high-fat, high sugar diet included 59% of energy derived from fat, 30% from carbohydrates, and 11% from protein. Serum levels of fasting glucose, triglyceride, cholesterol, liver enzymes, insulin, and hepatic tumor necrosis factor-alpha (TNF-α) gene expression were determined. Hepatic histology was examined by H&E stain. RESULTS Rats fed the high-fat, high sugar diet developed hepatic steatosis, and a moderate inflammation, which was associated with increased serum levels of liver enzymes, glucose, insulin, triglyceride, cholesterol, and hepatic TNF-α gene expression. CONCLUSION This rat model resembles the key features of human NAFLD/NASH and provides a simple pragmatic experimental model for elucidating the disease prevention and treatment.
