The Claim

In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) and overweight or obesity, the type of dietary pattern (Mediterranean, low-carbohydrate, or standard recommendations) has no independent effect on changes in liver fat content as measured by controlled attenuation parameter (CAP) when weight loss and ultra-processed food reduction are controlled for.

What the research says

Supports is higher

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

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Among adults with MASLD and excess weight, changing the type of diet—such as Mediterranean, low-carbohydrate, or standard guidelines—does not alter liver fat levels if weight loss and reduced intake of ultra-processed foods are the same across diets.

See the scientific wording

In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) and overweight or obesity, the specific type of dietary pattern (e.g., Mediterranean, low-carbohydrate, or standard recommendations) does not independently influence changes in liver fat content, as measured by controlled attenuation parameter (CAP), when weight loss and ultra-processed food reduction are accounted for.

Why this might work

When a person loses weight and eats fewer ultra-processed foods, the liver makes less fat from scratch and becomes more responsive to insulin, so fat builds up less in the liver.

  1. Study: Impact of weight loss and reduction of ultra-processed foods on liver fat content in MASLD: a randomized controlled trial.

    When people with fatty liver and extra weight lose weight and eat fewer processed foods, their liver fat improves — no matter if they eat Mediterranean, low-carb, or regular food. The type of diet doesn’t matter as much as losing weight and cutting out junk food.
