 Hi, I'm Dr. Olyth Selvan, Consulant Heptologist and Chairman Division of Liver Transplantation, Manipal Hospitals, Bangalore. The only treatment for fat liver disease as of now, which has been medically proven, is losing weight. Now losing weight, you can either do by having a healthy diet over a long period or by reducing weight with exercise. There are no medicines which have been proven to help fat liver over a period of time as of now.
