The Claim

In obese adults, higher baseline DunedinPACE epigenetic aging acceleration is associated with elevated insulin, HOMA-IR, and C-reactive protein levels and reduced high-density lipoprotein cholesterol, adiponectin, and ghrelin levels, while changes in DunedinPACE over 12 months are not associated with changes in these biomarkers.

In plain English

In obese adults, a faster epigenetic aging rate measured by DunedinPACE at the start of the study is linked to higher levels of insulin, inflammation markers, and lower levels of beneficial metabolic hormones, but changes in this aging rate over 12 months do not match changes in these metabolic markers.

See the scientific wording

In obese adults, higher DunedinPACE epigenetic aging acceleration is associated with elevated insulin, HOMA-IR, and C-reactive protein levels, and reduced high-density lipoprotein cholesterol, adiponectin, and ghrelin at baseline, indicating that this biomarker reflects a profile of metabolic dysfunction and inflammation, but changes in DunedinPACE over 12 months do not correspond to changes in these biomarkers, suggesting it may not mediate short-term cardiometabolic improvements from weight loss.

Why this might work

Long-term exposure to excess fat and high blood sugar causes cells to change their gene activity patterns in a way that speeds up biological aging. These changes are locked in and do not reverse quickly when weight is lost, so they stay high even as blood sugar and inflammation improve.

    In people with obesity, a biological clock called DunedinPACE is linked to worse metabolic health at the start, but when they lose weight, this clock doesn’t change in sync with their health improvements — so it’s not driving those changes.
