Does liver function not affect fasting greatly

The main items of liver test are: alanine aminotransferase (ALT), aspartate aminotransferase (AST), aspartate/alanine aminotransferase (AST/ALT), glutamyl transferase (GCP), alkaline phosphatase (AP), total bilirubin (TBI), direct bilirubin (DBL), indirect bilirubin (IBIL), urea nitrogen (BUN), creatinine (CRE), total cholesterol (CHOL), triglyceride (TRG), uric acid (UA). Many tests of liver function are directly related to diet. Alcohol can cause serum enzyme values to rise, while eating too greasy food or animal fat can cause blood lipids to rise.
