According to "Perfect Health Diet" (I'm not necessarily recommending the book), on p. 320 is the following statement:
Choline prevents metabolic syndrome, fatty liver, and obesity. Choline deficiency by itself causes metabolic syndrome (insulin resistance, elevated serum triglyceride levels, and high serum cholesterol levels) and obesity. Add in a low-protein diet, and it causes fatty liver disease. Choline supplementation rapidly cures fatty liver disease. In a mere twelve days, supplemental choline can reduce liver fat from 15 percent" to 4 percent."

There is also a detailed discussion on the Weston A Price (westonaprice.org) website by Christopher Masterjohn on Non Alcoholic Fatty Liver Disease. I imagine that, in addition to Ted's recommendation of 1-2 T/day of lecithin, a choline supplement (I suggest CDP Choline) would work a treat on Fatty Liver Disease. I'll leave further discussion and conclusions/recommendations for those more studied on the subject than I.
