Which causes a fatty liver?

Causes of fatty live: Many things. They range from inborn metabolic disorders to just plain eating too much. The liver is the only organ capable to produce fat, everywhere else is storage space. So by default, fat will be stored in the liver as well. There are some disease that will result in increased fat production or decreased use and therefore the storage of fat begins.

Ingested Carbs, Etoh: Body ability to store sugar low & sugar used, in small amts, before fats. Sugar (ie. All carbs) in food (beyond low ongoing needs) quickly converted by liver into fat & if liver unable to export fat fast enough; fatty liver results. Thus eliminate all carbs, including fruit, so liver has to convert fat back to sugar & ketones (quite healthy). Study dietdoctor, taubes, lusting, attia, fatheadmovie.
