Biochemical findings supporting excess liver fat. This simple figure signals the link between excess calories, leading to excess liver fat and the common biochemical findings of high glucose, altered liver enzymes (alanine aminotransferase (ALT) much greater than aspartate aminotransferase (AST)) and hypertriglyceridaemia. When these three biochemical features are present in overweight or obese individuals who are not excessive alcohol drinkers, the likelihood of non-alcoholic fatty liver disease (NAFLD) is high.
