Dietary restriction with adequate nutrition is considered the gold standard for delaying ageing and extending healthspan and lifespan in various species, as it impacts key nutrient-sensing signalling pathways to promote healthy longevity.
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. Dietary restriction in rodents and non-human primates affects key nutrient-sensing signalling pathways to increase healthspan and lifespan. This Review discusses these geroprotective mechanisms and recent insights suggesting that dietary restriction results in similar molecular and metabolic changes in humans, contributing to the prevention of ageing-associated diseases.
