The Claim

In obese adults, a very-low-calorie ketogenic diet and a standard low-calorie diet, over a two-month period, do not significantly alter liver stiffness.

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.

Description
1 study reviewed
In plain English

In obese adults, two types of low-calorie diets—ketogenic and standard—did not change liver stiffness after two months.

See the scientific wording

In obese adults, neither a very-low-calorie ketogenic diet nor a standard low-calorie diet significantly altered liver stiffness over two months, suggesting that short-term fat reduction does not immediately impact liver fibrosis markers.

Why this might work

Even when fat in the liver decreases, the scar-like tissue inside the liver does not break down quickly because the proteins that form the scar stay in place and new ones keep being made at the same rate.

  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.

    Even though people lost fat from their liver on both diets, their liver didn't become less scarred after two months — meaning losing fat doesn't quickly fix liver scarring.
