1.7 Years of Biological Aging In The Past 3.6 Years

In an earlier post (https://michaellustgarten.com/2018/06/26/maximizing-health-and-lifespan-is-calorie-restriction-essential/), I documented my aging.ai biologic age for 13 blood test measurements from 2016 – 2019. If you missed that post, here are those data:
agingai2Note that note my average biologic age has slowly increased from 2016 to 2019, from 28y in 2016 (2 measurements), to 29.25y in 2017 (6 measurements), to 29.5y in 2018 (6 measurements), to 30y in my June 2019 measurement.

To gain more insight into my 2019 prediction for biologic age, I kept measuring. On September 17, 2019, I had my worst biological age to date, 33y, based on the blood test data below:

Seeing a biological age that high (for me) was the motivation that I needed to finally stick to a mild caloric restriction, which I hypothesized would positively affect my biological age. I wrote about this in my recent Phenotypic Age post (https://michaellustgarten.com/2019/11/01/biological-age-31-3y-chronological-age-46y/). Did it work? Shown below is my blood test data for October 29th.

Based on that data, my biological age was 28y, and when averaging the 3 measurements in 2019 (so far!), my average biological age is 29.67y. When considering that my average biological age in 2016 was 28y, it looks like I’ve only aged ~1.7 years in 3.58 years of elapsed time!

  1. Glad you finally added CR or CRON, whichever it was (likely the later)! Was going to recommend CRON which I’ve been trying for close to a year (1 meal at 10:00 and sometimes snack around 4:00). So many years of bad habits for me have my Levine P-age at 69 vs chrono. 75 but will try to use your results and others to slow my aging as you have! Great work! On 2g Metformin/d makes CRON (pescatarian) easy for me and I think I’m getting less protein siding w/ those who think less is better (about 50g most days, ~30g on low days).

    1. I’ve been CR before, but it’s incredibly tough for me, even a mild CR (4%) isn’t easy, and that’s on a high-volume, nutrient dense diet. but for the good of science, let’s see how the data looks with continued CR in a few months!

12-16 Years Younger Than My Chronological Age: What's My Diet?

Sun Nov 10 , 2019
My average biological age in 2019 is 12 years younger than my chronological age (46y) based on the Phenotypic Age calculator (https://michaellustgarten.com/2019/11/01/biological-age-31-3y-chronological-age-46y/), and 16y younger based on aging.ai (https://michaellustgarten.com/2019/11/04/years-of-biological-aging-in-the-past-4-years/). One factor that likely contributes to my relatively youthful biological age is my diet. Shown below is my average daily dietary […]
