The Claim

In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) and overweight or obesity, a reduction in ultra-processed food intake is independently associated with a significant improvement in liver fat content as measured by controlled attenuation parameter (CAP), regardless of the specific dietary pattern followed.

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

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

In plain English

Adults with MASLD and overweight or obesity who eat less ultra-processed food have lower liver fat levels, measured by CAP, no matter what other foods they eat.

In adults with metabolic dysfunction-associated steatotic liver disease (MASLD) and overweight or obesity, a reduction in ultra-processed food intake is independently associated with a significant improvement in liver fat content, as measured by controlled attenuation parameter (CAP), regardless of the specific dietary pattern followed.

Why this might work

When people eat fewer ultra-processed foods, their liver gets less fructose, which stops the liver from making new fat. At the same time, the gut barrier gets stronger, so fewer bacterial toxins enter the bloodstream and trigger liver inflammation. This combination causes fat to build up less in the liver.

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

    This study found that people with fatty liver and extra weight improved their liver fat simply by eating fewer ultra-processed foods—even if they followed different diets. It wasn’t the type of diet that mattered most; cutting out processed foods did.
