Quantifying Biological Age: Blood Test #1 in 2021

Results for my first blood test in 2021 are in-what’s my biological age, and how am I optimizing it?

If you’re interested in calculating your biological age, the spreadsheet is included as an Excel file in this link:

  1. That was super helpful, a great video. Just this week I noticed what I thought was a link in my own diet of fruit intake making my phenoage worse so this was a timely video.

    Also, great catch on the salt. I wonder if getting salt in miso would be the way to go?

    1. Thanks Lee. I prefer to add the salt directly to cooked broccoli, rather than making miso soup. That said, I’m monitoring my BP regularly, and higher salt is correlated with worse creatinine and glucose levels, so I’m trying to be careful about its use.

  2. Hello Michael,

    Great video thanks. Would you mind sharing what’s your meals schedule? How many meals a day do you eat and when? And a sample of meals?

    Thanks a lot

    1. Thanks raphyduck. I usually eat all my food between 5AM – 3PM. I eat when I wake up between 5-6AM, including Brazil nuts, sardines, and a mix of nuts/seeds+dates, and green tea. Then I usually don’t eat until after I workout, ~9-10, and then eat most of the food for the day between 10-1PM.

      For representative dietary intake, see this video:

      There are small diet modifications since then, I’ll likely do a diet update video sooner rather than later.

  3. Congratulations on your latest results…which have to indicate you are on the right track (many right tracks, probably) toward health and longevity. And thanks for sharing, not only the results, but all the detailed inputs. Really informative and inspirational.

    1. Thanks Chicken Little. I put it all out there to share my approach (in part) for people to improve upon wherever I’m weak, so that lifespan can be further extended!

  4. do you use HsCrp or nomral CRP on this file?i get tested in 2 labs, one of the biggest and most reliable in europe and one small local lab and regularly get very very different results for HsCrp with same unit (0.017-0.016mg/dl vs 0.4-0.6mg/dl) did you notice anything similar according to lab machines used?

    1. The video is mostly about hs-CRP, and from my experience, it can vary not by 10-fold, but 4-5 fold depending on my diet, exercise training, etc. Also because the assay is performed using standardized protocols, I wouldn’t expect differences for different machines.
