Dear concerned. It is like a marker of fat status of liver and also whole body. Most of the time this status of liver is reversible provided it is mobilized as might be applicable to whole body fat too. Its like keeping body weight as near to normal limits, might also keeps liver fat or fatty liver too within normal limits. Some times a long standing high grade fatty liver might go to irreversible liver disorder ie CLD or liver failure for which only final remedy might be liver transplantation.
