The Claim
In male grey mouse lemurs, chronic caloric restriction of 30% initiated in early adulthood is associated with a 50% increase in median lifespan (from 6.4 to 9.6 years) and a 60% reduction in age-related mortality.
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.
Male grey mouse lemurs that eat 30% fewer calories starting in early adulthood live 50% longer on average and die less frequently from age-related causes compared to those eating normally.
See the scientific wording
In male grey mouse lemurs, a 30% chronic caloric restriction starting in early adulthood is associated with a 50% increase in median lifespan (from 6.4 to 9.6 years) and a 60% reduction in age-related mortality, suggesting that moderate calorie reduction may extend healthspan in primates.
Eating 30% less food lowers the body's energy use and reduces harmful byproducts from metabolism, which decreases damage to cells and tissues. This slows the breakdown of protective insulation around nerve fibers and reduces disease-causing inflammation, allowing the body to stay healthier longer and live more years.
What the research says
1 studyStudy: Caloric restriction increases lifespan but affects brain integrity in grey mouse lemur primates
Male mouse lemurs that ate 30% less food lived about half as long again and got sick less often, which means eating less helped them live healthier longer lives — even though their brains changed in some ways, it didn’t make them dumber.
