The Claim

In obese adults, a very-low-calorie ketogenic diet reduces liver fat fraction by a mean of 4.77% over two months, which is significantly greater than the 0.79% reduction observed with a standard low-calorie diet.

Source: MRI estimated changes in visceral adipose tissue and liver fat fraction in patients with obesity during a very low-calorie-ketogenic diet compared to a standard low-calorie diet.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

In obese adults, a very-low-calorie ketogenic diet reduces liver fat by 4.77% over two months, while a standard low-calorie diet reduces liver fat by only 0.79%.

See the scientific wording

In obese adults, a very-low-calorie ketogenic diet reduced liver fat fraction by a mean of 4.77% over two months, significantly more than the 0.79% reduction observed with a standard low-calorie diet, indicating a greater impact on hepatic steatosis.

Why this might work

When the body runs on ketones instead of glucose, the liver stops making new fat and starts burning existing fat for energy, which quickly reduces fat buildup in the liver.

What the research says

1 study
  1. Study: MRI estimated changes in visceral adipose tissue and liver fat fraction in patients with obesity during a very low-calorie-ketogenic diet compared to a standard low-calorie diet.

    In obese adults, a super-low-calorie keto diet cut liver fat nearly six times more than a regular low-calorie diet over two months, according to detailed MRI scans. This means the keto diet was much better at shrinking fatty liver.
