Abstract

Humans in modern societies typically consume food at least three times daily, while laboratory animals are fed ad libitum. Overconsumption of food with such eating patterns often leads to metabolic morbidities (insulin resistance, excessive accumulation of visceral fat, etc.), particularly when associated with a sedentary lifestyle. Because animals, including humans, evolved in environments where food was relatively scarce, they developed numerous adaptations that enabled them to function at a high level, both physically and cognitively, when in a food-deprived/fasted state. Intermittent fasting (IF) encompasses eating patterns in which individuals go extended time periods (e.g., 16–48h) with little or no energy intake, with intervening periods of normal food intake, on a recurring basis. We use the term periodic fasting (PF) to refer to IF with periods of fasting or fasting mimicking diets lasting from 2 to as many as 21 or more days. In laboratory rats and mice IF and PF have profound beneficial effects on many different indices of health and, importantly, can counteract disease processes and improve functional outcome in experimental models of a wide range of age-related disorders including diabetes, cardiovascular disease, cancers and neurological disorders such as Alzheimer’s disease Parkinson’s disease and stroke. Studies of IF (e.g., 60% energy restriction on 2 days per week or every other day), PF (e.g., a 5 day diet providing 750–1100 kcal) and time-restricted feeding (TRF; limiting the daily period of food intake to 8 h or less) in normal and overweight human subjects have demonstrated efficacy for weight loss and improvements in multiple health indicators including insulin resistance and reductions in risk factors for cardiovascular disease. The cellular and molecular mechanisms by which IF improves health and counteracts disease processes involve activation of adaptive cellular stress response signaling pathways that enhance mitochondrial health, DNA repair and autophagy. PF also promotes stem cell-based regeneration as well as long-lasting metabolic effects. Randomized controlled clinical trials of IF versus PF and isoenergetic continuous energy restriction in human subjects will be required to establish the efficacy of IF in improving general health, and preventing and managing major diseases of aging.

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

  • Intermittent fasting can protect neurons in animal models of disease, reduce the number of dopaminergic neurons and improve motor function in Parkinson's disease.

    “Intermittent fasting can protect neurons in animal models of disease, reduce the number of dopaminergic neurons and improve motor function in Parkinson's disease.250”

    From The role of gut dysbiosis in Parkinson’s disease: mechanistic insights and therapeutic options (2021) · cites this paper as [250]

    Section 2.1 reports that mice on alternate-day fasting had reduced loss of dopaminergic neurons and improved functional outcomes in a Parkinson’s disease model. This supports the neuroprotection and functional-outcome portions of the claim, but contradicts its statement that fasting reduces the number of dopaminergic neurons. (LLM, conf=0.90)

    Checked by a reasoning model — may be wrong.

  • Inducing starvation via alternate-day fasting or intermittent fasting reduces caloric intake and improves health markers related to cardiovascular risk in populations irrespective of obesity status.

    “Besides, inducing starvation via dietary regimens of alternate-day fasting [38] or intermittent fasting [39] has shown to reduce caloric intake and improve health markers related to cardiovascular risk in populations irrespective of obesity status.”
  • Healthy lifestyles, such as regular physical activity and healthy diet, are associated with weight loss and reduced risk of dementia by 0.68 times.

    “Therefore, healthy lifestyles, such as regular physical activity and healthy diet, are associated with weigh loss and reduced the risk of dementia by 0.68 times.375,376”
  • Intermittent fasting in rodents improved insulin and leptin sensitivity, increased ketone body levels, and reduced adiposity and inflammation.

    “Intermittent fasting in rodents improved insulin and leptin sensitivity increases ketone body levels and reduced adiposity and inflammation (235).”
  • Time-restricted eating has the potential to improve mitochondrial health and increase health span.

    “Interestingly, time-restricted eating, which involves regular periods of fasting, has emerged in the last few years as an intervention with the potential to improve mitochondrial health and increase health span [170,171].”

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.
