Is obesity really the leading cause of non-alcoholic fatty liver disease?
yes and no, hepatic steatosis ( or fatty liver ) without cirrhosis, is normally seen on fat people, but also on skinny people the problem is not the weight, the problem is the amount of triglycerides they have, and since normally overweight people do have high levels of triglycerides, they do get the fatty liver, but a skinny person with high levels of TRGs could have a fatty liver also (+ info)
