Strong Support

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.

Effect of long-term caloric restriction on DNA methylation measures of biological aging in healthy adults from the CALERIE trial

Randomized Controlled Trial
Human
2023 Mar

The study found that a new aging test called DunedinPACE could detect slowing of aging after 2 years of eating less, while two older tests couldn’t, which supports the idea that it’s better at measuring the effects of anti-aging treatments quickly.

Similar Assertions

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 a bit for two years might slow how fast your body ages on a cellular level, according to a study on healthy adults who aren’t overweight.

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.

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.
