To this single-centre randomized controlled comparative study it is planned to enroll 50 patients with non-alcoholic fatty liver disease. All these subjects will receive standard isocaloric diet for 14 days. Subjects of the main group will receive vegetable protein-and-fat cutlet or schnitzel insted of the same amount of standard (animal meat based) cutlet or schnitzel. Subjects of the control group will receive standard diet, with cutlets or schnitzels made of animal meat. It is planned to make repeated measurements of serum lipid profile and assess general well-being and tolerability of newly developed product compared to regular meal

• The intake of any medications that may affect the absorption, distribution, metabolism or excretion of investigational products or may lead to the induction or inhibition of microsomal enzymes (for example, indomethacin) - from the moment of randomization to the end of treatment.
• Any medical conditions that may significantly affect life expectancy, including known cancers;
• Any clinically significant immunological, endocrine, haematological, gastrointestinal, neurological or psychiatric diseases;
