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.

EFFECT OF LONG-TERM CALORIC RESTRICTION ON THE PACE OF BIOLOGICAL AGING IN HEALTHY ADULTS FROM THE CALERIE TRIAL

Randomized Controlled Trial

Human

The study looked at healthy adults who ate 25% fewer calories for 2 years and found they aged slightly slower based on a specific biological clock called DunedinPACE, just like the claim says.

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.

Cutting calories for two years doesn’t seem to change certain biological age clocks in healthy adults, even though other signs of aging improved.

Cutting calories helps people get healthier, and while a DNA aging test called DunedinPACE shows some of these benefits, it only catches a small part of the full picture.

A new aging test called DunedinPACE can spot small changes from healthy habits better than older tests, especially after just a couple of years of eating less — making it a better tool for testing anti-aging treatments quickly.
