Accumulation of excessive fat in the liver is the common denominator underlying the two most common and emerging causes of chronic liver disease, alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD), that are emerging public health issues globally. The burden of both ALD and NAFLD are increasing worldwide (1,2). ALD occur as a component of a broader perspective of alcohol abuse disorders, is frequently associated with psychiatric comorbidities and is the most frequent cause of morbidity, health care utilization and mortality in alcohol use disorders (3)(4)(5)(6). This is in contrast to NAFLD that occurs as an essential component of metabolic disorders that are associated with insulin resistance as the pathophysiological hallmark and is clinically manifest as hepatic, pancreatic, cardiac endothelial cell dysfunction and disease. In NAFLD, death is most commonly due to cardiovascular disease and often nonhepatic cancers apart from liver disease (7,8). The current global march of NAFLD as a public health challenge parallels the global upsurge for food intake, increase in per capita income, sedentary lifestyle, increasing body mass index and finally is an expression of an excess of caloric
