Abstract

Circadian clocks orchestrate periods of rest or activity and feeding or fasting over the course of a 24-hour day and maintain homeostasis. To assess whether a consolidated 24-hour cycle of feeding and fasting can sustain health, we explored the effect of time-restricted feeding (TRF; food access limited to daytime 12 hours every day) on neural, peripheral, and cardiovascular physiology in Drosophila melanogaster. We detected improved sleep, prevention of body weight gain, and deceleration of cardiac aging under TRF, even when caloric intake and activity were unchanged. We used temporal gene expression profiling and validation through classical genetics to identify the TCP-1 ring complex (TRiC) chaperonin, the mitochondrial electron transport chain complexes, and the circadian clock as pathways mediating the benefits of TRF.

  • CR delays age-associated muscle dysfunction in D. melanogaster and rhesus monkeys, and delays the onset of sarcopenia in rhesus monkeys.

    “Thus, despite the marked LBM reduction following CR in some species, CR delays age-associated muscle dysfunction in D. melanogaster [44] and rhesus monkeys [45], and delays the onset of sarcopenia in the latter [46].”

    From Resistance Training Prevents Muscle Loss Induced by Caloric Restriction in Obese Elderly Individuals: A Systematic Review and Meta-Analysis (2018) · cites this paper as [44]

    For the D. melanogaster claim attached to [44], the paper reports benefits from time-restricted feeding, not caloric restriction. Its unnumbered Abstract states that daily food intake was equivalent between groups and that the feeding regimen slowed age-related cardiac decline; it also says the flies’ gene-expression signature did not resemble dietary restriction. The rhesus-monkey claims have separate citations and are not judged here. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • Time-restricted feeding prevents body weight gain and decelerates cardiac aging in Drosophila.

    “Interestingly, the ability of TRF to prevent body weight gain and decelerate cardiac aging in Drosophila (86) indicates that it may represent a beneficial aspect of chrononutrition across species.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
