Here is a good read explaining 
"In epidemiological studies including people with type 2 diabetes, 62 to 69% of them also had nonalcoholic fatty liver disease. Another study found that 50% of patients with dyslipidemia (abnormally elevated cholesterol levels) had nonalcoholic fatty liver disease.
Obesity, metabolic syndrome, and heart disease are also closely linked with nonalcoholic fatty liver disease. In fact, the most common cause of death for nonalcoholic fatty liver disease patients is heart disease.
Gut health is another important variable to consider. When many people first try a high-fat, low-carb diet, they may focus on all of the fatty meat and cheese they can eat and forget about eating vegetables. Excess fat consumption with very little fiber can cause the gut microbiome to change tremendously. This leads to more lipopolysaccharides being absorbed and more inflammation in the body and the liver.
To optimize your diet to reverse disease, especially fatty liver disease, it is imperative to have low-carbohydrate vegetables with every meal. The combination of vegetables and carbohydrate restriction is what makes an ideal fatty liver diet."
