Abstract

During aging there is an increasing imbalance of energy intake and expenditure resulting in obesity, frailty, and metabolic disorders. For decades, research has shown that caloric restriction (CR) and exercise can postpone detrimental aspects of aging. These two interventions invoke a similar physiological signature involving pathways associated with stress responses and mitochondrial homeostasis. Nonetheless, CR is able to delay aging processes that result in an increase of both mean and maximum lifespan, whereas exercise primarily increases healthspan. Due to the strict dietary regime necessary to achieve the beneficial effects of CR, most studies to date have focused on rodents and non-human primates. As a consequence, there is vast interest in the development of compounds such as resveratrol, metformin and rapamycin that would activate the same metabolic- and stress-response pathways induced by these interventions without actually restricting caloric intake. Therefore the scope of this review is to (i) describe the benefits of CR and exercise in healthy individuals, (ii) discuss the role of these interventions in the diseased state, and (iii) examine some of the promising pharmacological alternatives such as CR- and exercise-mimetics.

  • Caloric restriction extends lifespan in many organisms and decreases the burden of senescent cells.

    “an intervention which has been shown to extend lifespan in a plethora of organisms and decrease the burden of senescent cells (Fontana et al., 2018; Mercken et al., 2012).”

  • Rapamycin and metformin can mimic effects of exercise and diet changes.

    “There are also drugs, such as rapamycin and metformin, that are able to mimic the effects of exercise and diet changes (Mercken et al., 2012).”

  • Prolongevity CR mimetics such as rapamycin and metformin have been proposed to modulate mitochondrial dynamics in obesity and age-related diseases.

  • Healthspan has not increased at the same pace as lifespan.

    “The fact that healthspan has not increased at the same pace as lifespan is a source of grave concern (Mercken et al., 2012).”

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.
