The Claim
In male grey mouse lemurs, chronic 30% caloric restriction is associated with preserved white matter volume in the genu and splenium of the corpus callosum and the fimbria hippocampi, and with accelerated loss of grey matter in the hippocampus, entorhinal cortex, and retrosplenial cortex over a four-year aging period.
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.
In male grey mouse lemurs, a 30% reduction in food intake over four years is linked to maintained white matter in certain brain regions but greater loss of grey matter in the hippocampus, entorhinal cortex, and retrosplenial cortex.

Eating less food slows down the breakdown of the brain's wiring by reducing damage to the fatty insulation around nerve fibers, but it speeds up the shrinking of brain cells in areas that handle memory and thinking because those cells get fewer signals to stay healthy and connected.
What the research says
1 studyStudy: Caloric restriction increases lifespan but affects brain integrity in grey mouse lemur primates
Eating 30% less food helped these tiny primates live longer and kept the brain's wiring (white matter) healthier, but made the brain's processing centers (grey matter) shrink faster — yet their thinking skills stayed the same.
