Losing weight—whether by eating better, exercising, taking medicine, or having weight-loss surgery—can help reduce fat, inflammation, and scarring in the liver of obese people with fatty liver...

When overweight people with fatty liver disease eat fewer carbs and calories, they lose weight and belly fat, but their body's ability to handle sugar doesn't really change.

In overweight adults with fatty liver disease, the more fat there is in the liver, the more sugar the liver tends to make, and this link is pretty strong even when considering other factors like body size.

After gastric bypass surgery, liver fat levels did not decrease significantly even though patients lost a lot of body fat, but when people lost the same amount of weight by eating fewer calories, their liver fat dropped substantially. This suggests that the method of weight loss affects liver fat differently.

After weight-loss surgery, changes in bile acids seem to help clean up fat in the liver and improve how the liver responds to insulin—even when people haven’t lost much weight yet.

If you're overweight and have too much fat in your liver, just changing to a healthier diet—without losing weight—might actually reverse early fatty liver in as little as two weeks.
