The Claim
In obese adults, DunedinPACE shows a stronger association with baseline cardiometabolic biomarkers compared to PCPhenoAge and PCGrimAge, and none of these epigenetic clocks exhibit meaningful changes following 12 months of weight loss.
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 obese adults, DunedinPACE is more closely linked to key metabolic health markers at the start of the study than two other epigenetic clocks, and none of the three clocks show significant changes after 12 months of weight loss.
See the scientific wording
DunedinPACE is more strongly associated with cardiometabolic biomarkers at baseline than PCPhenoAge or PCGrimAge in obese adults, suggesting it may be a more sensitive indicator of metabolic dysfunction in this population, but none of the epigenetic clocks change meaningfully over 12 months of weight loss.
When the body has excess fat and high levels of sugar and inflammation, it locks in a pattern of chemical marks on DNA that reflect accelerated aging. Even when fat is lost, these marks do not reset because the underlying metabolic stress continues to maintain them.
What the research says
1 studyIn obese adults, DunedinPACE better reflects metabolic health problems like high insulin and inflammation than other aging clocks, but none of these clocks changed much after a year of dieting — so they can't tell if someone got healthier in the short term.
