Changes to patients’ lifestyle, especially a modified dietary approach, play a key role in the treatment of nonalcoholic fatty
liver disease (NAFLD). A balanced, limiting and individually tailored nutritional scheme enables weight loss and an improvement
in the clinical picture of NAFLD. According to nutritional recommendations for patients with NAFLD, carbohydrates should
comprise 40–50% of total dietary energy. It is advisable to increase the amount of complex carbohydrates rich in dietary fibre.
A major role in the aetiology of NAFLD is played by excessive intake of fructose, which is related to the rise in consumption of
nonalcoholic beverages among subjects in developed countries. Fat intake should comprise < 30% of daily calories. It is essential
to increase consumption of food products rich in mono- and polyunsaturated fatty acids. Ingestion of protein should constitute
15–20% of total energy.
