Summarized by Masters of Longevity from Fight Aging!.

Review of evidence that fat infiltration into skeletal muscle increases with age and varies by sex, race, and body location, proposing myosteatosis as a potential aging biomarker.

Fat Infiltration into Muscle Tissue as a Biomarker of Aging
Key Takeaways
  • So there is relatively little drive to compare, contrast, and optimize approaches shown to slow or reverse aging in laboratory species.
  • One might hope that a robust measure of biological age would speed up the research community's efforts to build a basis for greater human longevity.
  • There are obviously a great many existing biomarkers of aging , some of which are very straightforward to measure.
