Robert Lustig explains how fatty liver disease raises your diabetes risk 3.5 times over. The condition causes insulin resistance, which exhausts your beta cells and leads to type 2 diabetes. Fatty liver can develop even in people with normal weight.

BMI binned on the X axis versus hazard risk ratio for fatty liver disease on the Y axis. What you can see is, yes, the obese have more, but take a look in the overweight. Even in the normal weight, you can still see the signal. And for diabetes, take a look at that. Look at the signal in the overweight and in the normal weight people. Bottom line, if you have fatty liver disease, you are 3.5 times more likely to develop type 2 diabetes in your lifetime than if you don't have fatty liver disease, because fatty liver disease is a precursor to that type 2 diabetes. If you develop type 2 diabetes, it's because you had fatty liver and because that fatty liver caused insulin resistance and then your beta cell burned out. So it is the precursor to the diabetes. And that's why we're talking about it. That's why I spent so much time talking about diabetes on the front end.
