To date, very few studies have examined the effects of the ketogenic diet in treating NAFLD. Thus, there is not enough evidence to recommend the ketogenic diet in people with fatty liver. A recent meta-analysis suggests that low carbohydrate diets (less than 40% of total calories) and moderate carbohydrates diets (40 to 50% of total calories) combined with regular physical activity may be beneficial to improve the risk factors of metabolic syndrome, promote weight loss, improve liver function and treat fatty liver. In general, a moderate carbohydrate restriction can be achieved by limiting sugars that have a poor nutritional value such as sugary drinks, sweets, added sugars and refined grains (white bread, white rice, white pasta, etc.).
Vitamin E supplementation (800 IU of a-tocopherol daily) is recommended for nondiabetic adults with histologically confirmed NASH to improve liver enzymes and histology. The efficacy of vitamin E supplementation as an antioxidant in improving biochemical and/or histological abnormalities in NASH has been studied in several clinical studies. However, there is considerable heterogeneity among studies with respect to study power, entry criteria, vitamin E dosage, vitamin E formulations used, additional use of other antioxidants or medications, and histological data to assess outcomes. Despite these limitations, it has been concluded that vitamin E use is associated with improvement in liver enzymes (decrease in ALT, AST), steatosis and inflammation, as well as resolution of steatohepatitis.
