best refs for blood lab ranges for CR practitioners for most common labs (eg CBC)

[kpfleger]

Has anyone built a list of normal ranges for common blood labs for CR diets? Or have links to good data on the subject?

Many labs are affected by CR or other healthy diets. Eg WBC is lower under WFPB vegan & CR diets. BUN levels are lower in low-protein diets. Etc.

I'm aware that Luigi Fontana has published some studies with some lab values (eg https://www.pnas.org/doi/10.1073/pnas.0308291101) but I haven't seen any papers that cover even the full range of stuff a super-common & inexpensive CBC would provide. Eg BUN is not in that paper. The CALERIE cohort has been studied extensively with several papers published---do any datasets publicly available anywhere present the summary stats for most CBC blood labs for this cohort? I know Fontana did some work with members of the CR Society a ways back---is there a summary table with labs for those tests that covers more than the basic half dozen CVD risk factors? I don't have time to trace down all the papers and study what's provided in the supplemental material at the moment, and curious if someone else has done that or if they know of a place where researchers have put the summary stats data for the broader list of markers.

I know Dean has shared his labs in these forums. Have there been any efforts to collect more than n=1 here, even if only n=5ish or something like that?

I submitted my numbers several years ago.  They haven't changed significantly.

Sure, I don't expect lots of people to share with attribution to the individual level. I'm more wanting summary stats from large cohorts like CALERIE or semi-large cohorts like the groups Fontana gathered data from, where the summary stats give away no one's individual numbers.

...Whereas others believe in flaunting their values ! There has been a recent thread on this topic, with some values discussed, but I don't remember where exactly.

Hi kpfleger,

Dr. Luigi Fontana does outline some of what you are looking for in this outstanding lecture of his. You’ll have to scroll the video ahead a few minutes before it begins.

By the way, here’s another great piece of work from Luigi Fontana from the Live Long and Master Aging Podcast.

This isn’t more than a N=1 sample as you’ve requested, but here’s my bloodwork results after 11.5 years of mild CR. I will also share my “visual” results since sometimes a picture tells a lot in addition to measurable metrics.

Well, actually we discovered, in another thread, that the N  raised to at least 4, me included (not practicing conscious CR but DR=dietary restriction).
