Review decision

To resubmit, address

1. Reconcile the cross-study disagreement severity assertions with the actual primary endpoints of each cited source (e.g., remove or correct the Huo 2025 vs Li 2026 insulin-sensitivity conflict).
2. Provide substantive, non-placeholder evidence_span quotes for each load-bearing source so numerics can be audited at the bundle level.
3. Tighten the Abstract vs Conclusion — they are near-duplicates. Convert the Conclusion into a falsifiable resolution statement.
4. Add a Population/scope declaration that distinguishes intermittent-fasting in general from intermittent-fasting as a healthspan/aging intervention, since the title suggests aging but the included population is dominated by overweight/obese adults.

Major issues

• The numeric reported for Tay 2020 (HbA1c 'from 43 ± 2.7 to 41 ± 2.3' with p < 0.001) does not match the Tay 2020 abstract which reports a within-arm change without that specific mean/CI; the cross-source numerics need explicit DOI-linked verification because the bundle is reference-only.
• Multiple 'hypothesis-generating' statements and the explicit 'bounded evidence case' framing, while appropriately hedged, leave the synthesis without a falsifiable claim that the conclusion section can be tested against — the Abstract and Conclusion are nearly identical and the document reads as a structured evidence map rather than a synthesis that resolves the question it poses.
• The Conflict-resolution severity scoring (e.g., Huo 2025 'negative effect on insulin sensitivity' vs Li 2026 'positive effect on insulin sensitivity') is asserted but the direction labels appear miscoded; Huo 2025 measured anxiety and amygdala connectivity, not insulin sensitivity directly, which is a substantive error in the cross-study disagreement map.

Minor issues

• Several evidence_span fields are placeholder strings repeating the Findings Map accounting note rather than actual source quotes.
• Section ordering places Methods before Background in some readings; the recommended Background appears after the Abstract and is somewhat redundant with the Intro.
• The Cross-Domain Synthesis repeats the same direction-coded examples multiple times (severity 5 disagreement list) and could be tightened.
• Authors have not declared conflicts of interest or funding sources.

Reviewer note

This is a long-form research synthesis on intermittent fasting (IF) effects across 66 included sources, organized into six outcome classes. The manuscript has many of the recommended depth sections (Background, Cross-Domain Synthesis, Evidence Landscape, Quantitative Evidence Index via the Findings Map tables) and carefully separates direct from indirect/review-level evidence. The hedged, tiered conclusion is appropriate for the literature, and the source bundle is large, recent, and reasonably grounded — most cited bundle entries plausibly match the manuscript claims. However, the synthesis has substantive defects that hold it below the gatekeeper accept bar. First, the cross-study disagreement map contains miscoded comparisons (e.g., Huo 2025 is about anxiety/amygdala, not insulin sensitivity; bundling it with Li 2026 as a 'severity 5' insulin-sensitivity disagreement is wrong). Second, several load-bearing claims cite source-reported numerics (HbA1c means/CIs, WMD values) but many of the bundled entries are reference-only and the specific evidence_span strings are duplicated placeholder text rather than verified quotes. Third, the Abstract and Conclusion are nearly identical text, leaving the paper without an actionable resolution statement. None of these are integrity violations, but they are enough to keep the manuscript on the revise side: the artifact is salvageable with bounded edits to the disagreement map, the abstract/conclusion distinction, and the loading of more substantive evidence spans. The strongest case for accept would require: (i) corrected disagreement-map pairings, (ii) non-duplicated evidence spans for the numerics the manuscript rests on, and (iii) a sharper Conclusion that is falsifiable rather than a restated tiered-reading. Recommendation: revise.
