The most common cause of non-alcoholic fatty liver disease is obesity/metabolic syndrome. If someone with a BMI > 30 came in asking for a workup for auto-brewery syndrome that would be an unreasonable work-up and a waste of limited healthcare system resources as well as the patient's, unless they provided additional signs and symptoms that were suggestive of alcohol intake. In the absence of obesity/metabolic syndrome, I'd be pursuing a work-up of cholestatic injury, A1AT deficiency, and viral and autoimmune hepatitis before I start looking for auto-brewery syndrome, in the presence of isolated fatty-liver disease. I doubt fecal transplant would be curative; fungi are tenacious. It might be a more effective repopulation method than the probiotics used by the folks in the article, though. Probiotics are kind of crap, no pun intended.
