HDL Update: Age-Related Changes, All-Cause Mortality Risk, And Progress Towards The Optimal Range

2 Replies

In November 2020, I made a HDL video based on a meta-analysis in ~3.4 million subjects that was published in July 2020. In Dec 2020, a larger study (n=15.8 million subjects) was published-those data are presented in the video, and compared against the meta-analysis.

In addition, I’ve tested my HDL 2 more times since November 2020, so how’s my progress for getting it into the optimal range? Also, I attempt to derive clinical significance by identifying correlations for higher HDL with lower Lp(a) and hs-CRP.

Quantifying Biological Age With Aging.ai: 24 Blood Tests Since 2009

5 Replies

The maximal reduction for biological age when using the biological age calculator, Phenotypic Age, is ~20 years. In other words, if I’m 80 years old and my biomarkers are all reflective of youth, the lowest possible biological age will be ~60 years old. One reason for that is the inclusion of chronological age in the prediction of biological age, which adds strength to the correlation while simultaneously limiting the maximal biological age reduction.

To account for the possibility that youthful biomarkers at an older chronological age can yield a biological age that is more than 20 years younger, it’s important to quantify biological age using a tool that doesn’t include chronological age in its calculation. Aging.ai fits that criterion, and in the video I present biological age data with use of aging.ai for 24 blood tests since 2009.

Microbial Products Affect the Hallmarks Of Aging: 1) Mitochondrial Function

Leave a reply

The Hallmarks of Aging are well established, but what is less discussed is the impact of microbes and/or microbial products. The bacterial metabolite, LPS, increases during aging, and it negatively impacts mitochondrial function, thereby demonstrating a role for microbial products on one of the Hallmarks of Aging, mitochondrial dysfunction.

LDL Cholesterol: What’s Optimal For Health And Longevity?

Leave a reply

LDL is arguably the most debated biomarker in terms of what’s optimal for health. In the video, I present data showing that 100 – 140, not 50 – 70 mg/dL may be optimal in terms of minimizing disease risk and maximizing longevity.
