#386 - Aging clocks—what they measure, how they work, and their clinical and real-world relevance

The podcast explores the utility of aging clocks, which aim to predict biological age and rate of aging, as opposed to chronological age. It highlights the potential of aging clocks to compress the multidimensional aspects of aging into a single number, offering speed and individual feedback for clinical trials and personal health monitoring. The discussion centers on two studies: one examining the impact of omega-3, vitamin D, and exercise on epigenetic aging clocks, and another using brain imaging to estimate the pace of aging. While these clocks show promise in detecting early biological signals, the podcast cautions against their use as definitive health metrics for individual decision-making, given the limitations of current evidence and the availability of more reliable biomarkers.
