Can eating less slow down aging?
EFFECT OF LONG-TERM CALORIC RESTRICTION ON THE PACE OF BIOLOGICAL AGING IN HEALTHY ADULTS FROM THE CALERIE TRIAL

Surprising Findings
Caloric restriction slowed aging on DunedinPACE but not on PhenoAge or GrimAge
Many assume that if an intervention slows aging, it should show up across multiple biological age measures. The fact that only one clock detected the effect challenges the idea of a universal 'biological age'.
Practical Takeaways
Sustained caloric restriction may modestly slow biological aging in healthy adults, based on one epigenetic measure.

If you're already eating a really healthy and balanced diet, cutting back on calories probably won't help you live much longer.
If healthy-weight adults eat 25% less food for two years, it might slow down how fast their body ages—based on a special aging test—though not all aging tests showed a change.
Cutting calories doesn’t seem to slow aging in healthy-weight adults when measured with certain DNA tests, and the effect might depend on which test you use.
If your body ages just a little slower — like 3% slower — you might be 15% less likely to die sooner, especially as you get older. Even tiny changes in how fast you age could really matter for your health over time.
