... increased caffeine intake may reduce fatty liver in people with non-alcoholic fatty liver disease (NAFLD).
Worldwide, 70 percent of people diagnosed with diabetes and obesity have NAFLD, the major cause of fatty liver not due to excessive alcohol consumption. It is estimated that 30 percent of adults in the United States have this condition,... There are no effective treatments for NAFLD except diet and exercise.
... caffeine stimulates the metabolization of lipids stored in liver cells and decreased the fatty liver of mice that were fed a high-fat diet. These findings suggest that consuming the equivalent caffeine intake of four cups of coffee or tea a day may be beneficial in preventing and protecting against the progression of NAFLD in humans.

An obese diabetic who has fatty liver, I didn't know that 70% of people like me have it too. I've been drinking about 8 cups of green tea daily, and still got this problem. It seemed strange to me that the author equated the caffeine of coffee and tea, as if he isn't well informed about caffeine content.
