The article doesn't support "calori restriction" -> "longer lifespan"

No clinical trial has been performed involving humans. Two trials have been performed involving primates, but have not demonstrated increases in median lifespan. A study of rhesus monkeys begun in 1987 by the National Institute on Aging published results in August 2012 that found evidence of health benefits, but did not demonstrate increased median lifespan.[2] A study by the University of Wisconsin beginning in 1989 is still ongoing.[1][3][4] Research on maximum life span in that study is still ongoing.
