Abstract

Dietary restriction with adequate nutrition is the gold standard for delaying ageing and extending healthspan and lifespan in diverse species, including rodents and non-human primates. In this Review, we discuss the effects of dietary restriction in these mammalian model organisms and discuss accumulating data that suggest that dietary restriction results in many of the same physiological, metabolic and molecular changes responsible for the prevention of multiple ageing-associated diseases in humans. We further discuss how different forms of fasting, protein restriction and specific reductions in the levels of essential amino acids such as methionine and the branched-chain amino acids selectively impact the activity of AKT, FOXO, mTOR, nicotinamide adenine dinucleotide (NAD+), AMP-activated protein kinase (AMPK) and fibroblast growth factor 21 (FGF21), which are key components of some of the most important nutrient-sensing geroprotective signalling pathways that promote healthy longevity.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Dietary interventions such as caloric restriction and intermittent fasting might protect against age-related dysfunction and diseases based on animal studies.

    “Dietary interventions, such as caloric restriction and intermittent fasting, might be protective against development of age-related dysfunction and diseases based on studies in animal models134,135.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [135]

  • Dietary restriction mimetics reverse age-related declines in stem cell function.

    “In addition to dietary interventions, dietary restriction mimetics (for example, pharmacological compounds or metabolites that mimic dietary restriction) have also been shown to reverse age-related declines in stem cell function209 (TABLE 1).”

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.
