The Claim

In adults with metabolic dysfunction–associated steatotic liver disease (MASLD), time-restricted feeding (16:8) is associated with greater reductions in body weight and BMI compared to continuous energy restriction, but is not associated with significant changes in liver fat, transaminases, or glucose metabolism.

In plain English

In adults with MASLD, eating within an 8-hour window each day leads to greater weight and BMI loss than eating throughout the day, but does not result in measurable changes in liver fat, liver enzyme levels, or blood sugar control.

See the scientific wording

In adults with metabolic dysfunction–associated steatotic liver disease (MASLD), time-restricted feeding (16:8) is associated with greater reductions in body weight and BMI than continuous energy restriction, but shows no significant effect on liver fat, transaminases, or glucose metabolism.

Why this might work

When a person eats only during an 8-hour window each day, their body switches from using sugar to burning fat for energy during the long fasting period. This increases the amount of fat released from fat tissue into the blood and used by muscles, which causes more weight and lower body mass index. However, the liver does not process less fat because the rate at which fat enters and leaves the liver stays balanced, so liver fat, liver enzymes, and blood sugar levels do not change.

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

    For people with fatty liver, eating only during an 8-hour window helped them lose a little more weight and lower their BMI than just eating fewer calories all day — but it didn’t do any better at reducing liver fat, liver enzymes, or blood sugar levels.
