The Claim
The DunedinPACE DNA methylation biomarker demonstrates greater sensitivity than PhenoAge and GrimAge in detecting changes in biological aging resulting from caloric restriction over a two-year period in healthy adults.
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.
DunedinPACE measures biological aging more precisely than PhenoAge or GrimAge when people reduce their calorie intake for two years.
See the scientific wording
The DunedinPACE DNA methylation biomarker is more sensitive than PhenoAge or GrimAge to detect changes in biological aging induced by caloric restriction over a two-year period in healthy adults.
Eating fewer calories changes how chemical tags attach to DNA in blood cells, especially at sites linked to metabolism and inflammation. These changes make the body's aging process slower, and this slowdown is detected by the DunedinPACE biomarker because it is built from those specific DNA tags. Other aging biomarkers do not detect this change because they use different DNA sites that are not affected by calorie reduction.
What the research says
1 studyScientists found that eating fewer calories slowed down a specific biological aging clock called DunedinPACE, but didn't change two other popular aging clocks. This means DunedinPACE is better at noticing small, early changes in aging from diet.
