Lean NAFLD, defined as fatty liver in non-obese individuals, is a significant subset of NAFLD (7-20%) and is associated with insulin resistance and metabolic dysfunction despite normal BMI.

You do not need to be overweight to develop fatty liver. Lean NAFLD affects 7-20% of NAFLD cases and is linked to insulin resistance and metabolic issues. If you have fatty liver, focus on metabolic health markers like blood sugar and insulin sensitivity, not just your weight.
