title: Dietary restriction would probably not increase longevity in human beings and other species able to leave unsuitable environments.
abstract: This article argues that dietary restriction would not increase longevity in species able to leave a place where they are subjected to starvation. Human beings can emigrate when feeding conditions are a threat to survival and thus they would not live longer if subjected to dietary restriction.
