The context receipts provide source breadth and boundary checks, not independent confirmation of the lead claim.\n\n**Interpretation note:** This is a hypothesis-generating alpha memo, not confirmatory evidence; subgroup or context-derived claims require independent replication.\n\n## Why this is surprising\n\nReal tension: the useful signal is narrower than the topic label. The lead receipts support the core claim, while the added A/B context receipts define where that claim may generalize, fail, or need a separate extraction.\n\n## Evidence receipts\n\n- `fact_id=100758` (`A_core`) — RT reduced 93.5% of CR-induced LBM loss doi=10.3390/nu10040423\n- `fact_id=100761` (`A_core`) — change in strength/LBM ratio tended to be different (p = 0.07) following CRRT (20.9 ± 23.1%) and CR (−7.5 ± 9.9%) doi=10.3390/nu10040423\n- `fact_id=183811` (`A_core`) — when TRF is combined with caloric restriction, weight loss is >5% of the initial body weight doi=10.3390/nu14224778\n- `fact_id=185351` (`A_core`) — Studies with subtherapeutic dosing typically used more moderate caloric restrictions (reducing energy intake by 500-600 kcal/day) and the weighted mean remission rate was 6.9% doi=10.1177/1559827620930962\n- `fact_id=161504` (`A_core`) — 30% CR was sufficient to extend the life span by 10% doi=10.1126/science.abk0297\n- `fact_id=162990` (`A_core`) — 30% CR in young male mice decreased fat mass and improved glucose tolerance and insulin sensitivity doi=10.7554/elife.88080\n\n## Context receipts\n\n_Boundary evidence only; these receipts broaden source context but do not independently prove the lead claim._\n\n- `fact_id=100759` (`B_context`) — 0.819 kg [0.364 to 1.273] of CR-induced LBM loss prevented doi=10.3390/nu10040423\n- `fact_id=173560` (`B_context`) — a 7-day water-only fast leads to an average weight loss of 5.7 kg (±0.8 kg) among 12 volunteers doi=10.1038/s42255-024-01008-9\n- `fact_id=141623` (`B_context`) — 40% caloric restriction had the strongest lifespan extension effect. doi=10.1038/s41586-024-08026-3\n\n## What this changes\n\nTreat this as a focused working signal, not a broad topic claim. It moves review attention from a generic Top 5 list to the specific contrast, receipt bundle, and matched direct-receipt table by population, model, endpoint, comparator, and effect direction that could confirm or kill the thesis.\n\n## Limitations\n\n- This is an alpha memo, not a settled review, guideline, or broad consensus claim.\n- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.\n- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.\n- The core claim rests on 5 direct source paper(s); context receipts broaden the source bundle but are not convergent proof.\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## What would weaken this\n\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## Strongest counter-evidence\n\n- `fact_id=146839` (`A_core`) — n = 220 adults without obesity were randomized to 25% CR or ad libitum control diet for 2 yr Source: Effect of long-term caloric restriction on DNA methylation measures of biological aging in healthy adults from the CALERIE trial\n\n## Next extraction\n\n- Extract independent A_core/B_context receipts that test the lead contrast directly.\n- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.\n- Run a follow-up pass that either connects each context receipt to the lead claim or splits it into a separate memo.\n","metadata":{"abstract":"The direct receipts support a narrow working claim: RT reduced 93.5% of CR-induced LBM loss; change in strength/LBM ratio tended to be different (p = 0.07) following CRRT (20.9 ± 23.1%) and CR (−7.5 ± 9.9%).
