Diet rankings differed for weight and liver fat in fatty liver disease
A network meta-analysis ranked intermittent fasting highest for weight outcomes and the Mediterranean diet highest for liver-related outcomes, with important reporting gaps.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
For adults with metabolic dysfunction-associated fatty liver disease, intermittent fasting ranked highest for weight and waist outcomes. The Mediterranean diet ranked highest for liver-related outcomes, with reductions in liver fat and triglycerides. The abstract leaves the reference groups behind its estimates unclear, and the authors call for stronger long-term trials to validate these findings.
The abstract omits trial counts, participant counts, intervention durations and reference groups for the reported effects. Without those details, the size, precision and applicability of the reported diet differences are difficult to judge.
Different endpoints led to different rankings
Weight, waist circumference, liver fat and blood triglycerides capture distinct outcomes. The reported rankings therefore do not establish a single best diet across all of them, or show that changes in these measures prevent clinical complications.
Fasting intensity remains an open question
A sensitivity analysis suggested that more intensive fasting regimens might account for stronger improvements than time-restricted eating. The abstract does not describe those regimens or provide enough comparison detail to support a specific fasting schedule.
