The Claim
Caloric restriction extended the median lifespan of rhesus monkeys beyond the historical norm of approximately 26 years observed in control animals at the research center.
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 fed a reduced-calorie diet lived longer than the typical lifespan of 26 years seen in monkeys fed normally at the same research center.
See the scientific wording
The median lifespan of control rhesus monkeys in this study (~26 years) aligns with historical norms for the research center, indicating that caloric restriction extended survival beyond typical aging trajectories in this population.
Eating less lowers the amount of harmful molecules made during energy production, which reduces damage to cells and DNA. This lets cells repair themselves more effectively and stay functional longer, delaying the breakdown of tissues and organs that normally happens with age.
What the research says
1 studyStudy: Caloric restriction reduces age-related and all-cause mortality in rhesus monkeys
Monkeys that ate less lived longer than monkeys that ate normally, and the normal-eating monkeys lived about as long as other monkeys at the same place. So cutting calories helped them live beyond the usual monkey lifespan.
