The Study
Intermittent fasting versus continuous energy restriction in MASLD: a systematic review and meta-analysis
This study looked at lots of different experiments where people tried two kinds of diets and saw what happened. It found that one diet (intermittent fasting) helped people lose a little more weight and lower bad cholesterol than the other. But it didn't prove it fixed fatty liver for sure — the data was mixed, like when two different tools give different answers.
Analysis score
Maximum 100 for a systematic review with meta-analysis.
Where the score came from
This study looked at whether skipping meals on certain days (intermittent fasting) helps people with fatty liver disease better than just eating fewer calories every day.

Key takeaways
Summary
Based on the study abstract and findings.
- 1The weight loss difference is small and may not be noticeable to most people; the LDL drop is minor and its health impact is unclear; liver fat didn't improve more with fasting when measured by the most reliable scan.
- 2People who fasted lost a bit more weight (about 1.3 kg) and had slightly lower BMI and LDL cholesterol than those who ate less every day.
- 3But scans showing liver fat (MRI) didn't show any difference between the two diets.

Claims (5)
Among adults with MASLD, intermittent fasting leads to slightly more weight loss and lower BMI than continuous calorie restriction when followed for 8 to 52 weeks.
Among adults with metabolic dysfunction–associated steatotic liver disease, intermittent fasting is associated with a small decrease in LDL cholesterol compared to continuous calorie restriction, but does not significantly change total cholesterol, triglycerides, or HDL cholesterol.
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.
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.
In adults with MASLD, intermittent fasting (5:2) is linked to a larger decrease in liver fat measured by CAP than daily calorie restriction, but this difference does not appear when liver fat is measured by MRI-PDFF and vanishes when small studies are removed from the analysis.
