The diet-induced fatty liver model is established by feeding animals with high-fat and high-sugar diets, leading to overnutrition – from excessive amounts of lipids, cholesterol, and/or carbohydrates in the food - which cannot be fully absorbed and utilized. This overnutrition results in lipids accumulation, further inflammatory changes, and fibrosis. This model is similar to human NAFLD and is the most commonly used NAFLD animal model. Different diet-induced models vary in characteristics.
