Doesn't really seem like calorie restriction. The monkeys who died younger would have definitely been considered unhealthy and gluttonous.
And it's no secret that being overweight causes premature aging, health problems and eventually premature death.
- defterGoose 9y agoThey controlled for diet, natural feeding tendencies, etc. presumably to match conditions in the wild. They never said the monkeys who "naturally" ate the most DIDN'T die first; they probably did. But that certainly doesn't mean that calorie restriction below the "average" feeding tendency doesn't provide benefit.
- jm2721 9y agoTotally agree. If you look at the two parallel studies, it seems like diet had a huge effect on the outcome. The NIA study found no significant difference in both groups, and fed the monkeys varied source of protein. The UW study found health improvements in the CR monkeys but fed them 'significantly higher amount of sucrose compared to the NIA diet'. https://www.nia.nih.gov/newsroom/announcements/2017/01/calorie-restriction-improves-health-survival-rhesus-monkeys https://www.nia.nih.gov/newsroom/announcements/2017/01/calor... https://www.ncbi.nlm.nih.gov/pubmed/28094793 https://www.ncbi.nlm.nih.gov/pubmed/28094793 https://www.nature.com/articles/ncomms14063 https://www.nature.com/articles/ncomms14063
