The Claim
Caloric restriction of approximately 30% in adult rhesus monkeys, initiated between 7 and 14 years of age and maintained for over two decades, is associated with a 2.9-fold reduction in the rate of death from age-related causes and a 1.8-fold reduction in all-cause mortality compared to control animals fed ad libitum.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Rhesus monkeys that ate 30% fewer calories than normal, starting between ages 7 and 14 and continuing for more than 20 years, died from age-related causes at 2.9 times lower rates and from any cause at 1.8 times lower rates than monkeys that ate without restriction.
See the scientific wording
Caloric restriction of approximately 30% in adult rhesus monkeys, initiated between 7 and 14 years of age and maintained for over two decades, is associated with a 2.9-fold reduction in the rate of death from age-related causes and a 1.8-fold reduction in all-cause mortality compared to control animals fed ad libitum, suggesting that sustained dietary restriction may delay aging and extend lifespan in non-human primates.
Eating less food lowers the amount of energy the body processes, which reduces wear and tear on cells and allows the body to focus on repairing damage instead of growing and storing energy. This keeps cells healthier for longer and prevents the buildup of problems that cause aging and death.
What the research says
1 studyStudy: Caloric restriction reduces age-related and all-cause mortality in rhesus monkeys
Monkeys that ate 30% less food than usual for over 20 years lived much longer and got sick less often from old age than monkeys that ate as much as they wanted. This suggests eating less might help primates, including possibly humans, live healthier, longer lives.
