“Doctors recommend weight loss to treat nonalcoholic fatty liver disease (NAFLD), either nonalcoholic fatty liver (NAFL) or nonalcoholic steatohepatitis (NASH). Weight loss can reduce fat, inflammation, and fibrosis—or scarring—in the liver.

If you are overweight or have obesity, losing weight by making healthy food choices, limiting portion sizes, and being physically active can improve NAFLD—either NAFL or NASH. Losing at least 3% to 5% of your body weight can reduce fat in the liver. You may need to lose up to 7% to 10% of your body weight to reduce liver inflammation and fibrosis. Physical activity alone, even without weight loss, is also beneficial.

Doctors recommend gradually losing weight to improve NAFLD. Rapid weight loss and malnutrition can make liver disease worse.”.
