The Claim

In adults with metabolic dysfunction–associated steatotic liver disease (MASLD), intermittent fasting does not result in a statistically significant reduction in liver fat as measured by magnetic resonance imaging–proton density fat fraction (MRI-PDFF) compared to continuous energy restriction, despite a transient signal in ultrasound-based CAP measurements.

In plain English

In adults with MASLD, intermittent fasting does not reduce liver fat more than continuous calorie restriction when measured by MRI, even though ultrasound shows a temporary change.

See the scientific wording

In adults with metabolic dysfunction–associated steatotic liver disease (MASLD), intermittent fasting does not lead to a statistically significant reduction in liver fat measured by magnetic resonance imaging–proton density fat fraction (MRI-PDFF) compared to continuous energy restriction, despite a transient signal in ultrasound-based CAP measurements.

Why this might work

When a person goes without food for periods of time, the liver switches from using sugar to burning fat for energy. This increases the breakdown of fat inside liver cells, which should reduce fat buildup. However, the liver also continues to receive fat from the body’s fat stores and makes new fat molecules, so the total fat in the liver does not drop enough to be measured as a significant change.

  1. Study: Intermittent fasting versus continuous energy restriction in MASLD: a systematic review and meta-analysis

    For people with fatty liver disease, eating only during certain hours didn’t reduce liver fat more than just eating fewer calories every day—when measured by the best scan method (MRI). Even though a simpler test (ultrasound) hinted at a benefit, the more accurate scan showed no difference.
