Selections from the CR (mailing list) archives

The recent interest in fasting, coupled with the fact that many -- perhaps most -- member profiles here on this Forum were never exposed to old mailing list, leads me to think some archival emails need resurfacing. I have all Main List postings roughly mid-2003 to "present" (in a Thunderbird database; easily searchable, filterable, and categorizable on myriad parameters including 'Subject", "Body", "Sender", etc. etc ). From roughly early 2000 to mid-2003, I was using AOL Mail, which I can data-mine (to a much more limited extent).

Times a wastin' ... so I'll get right to my first topic in the next post. Any objections .. Tim or another Mod can censor or delete as necessary.

Searching /filtering my "Michael Rae" email folder for header subject keyword "fasting" reveals 30 messages Feb. 2004-Jan. 2015.

That's actually a previous andn narrower report from the same group. The 
new paper identified by Bill is:


1: Chaix A, Zarrinpar A, Miu P, Panda S. Time-Restricted Feeding Is a
Preventative and Therapeutic Intervention against Diverse Nutritional 
Challenges.
Cell Metab. 2014 Dec 2;20(6):991-1005. doi: 10.1016/j.cmet.2014.11.001.

PMID: 25470547; PubMed Central PMCID: PMC4255155.

Because it is new, it is NOT free full-text.

Bill: the List software does not pass through attachments, and we don't 
have the server space for them anyway. The usual etiquette is (if you 
are willing to do it) to offer to send the pdf to anyone who asks for a 
copy -- OFF LIST, via direct request to your personal email. It's also 
helpful to post key extracts from the paper (not the full text, please: 
copyrighth issues, etc).

This looks interesting. my own review of the Time-Restricted Feeding 
data has left me somewhat puzzled by seeming inconsistencies; it's a 
surprising paradigm.

Participants take multivitamins to avoid nutrition deficiency, and they’re
encouraged not to exercise on fasting days.
 
I wonder if they take the multivitamins on fasting days only. Would you
happen to know?

The piece says that "This is not an absolute fast, because it does not 
require you to give up food for the entire day. Instead, Dr. Luigi 
Fontana, ... says to aim for 500 calories on a fasting day. "
 
I had assumed that if you eat well on the non-fasting days
it wouldn't matter on the fasting days.

The body is really very good at handling the non-intake of nutrients for 
a day or even a week; still, if it was me, and I was for some reason 
going to do an absolute fast for 24 h, I'd be inclined to take an RDAish 
supplement of water-soluble, minimally-stored vitamins (C, most Bs) on 
fast days just in case. (if, that is, I could even FIND such a thing as 
an RDAish B complex...).

So I recently got my fasting insulin results back.

And they were below the threshold of detection (<2)

I often notice that I feel really bad after eating too many carbs.

Could it mean that when I eat carbs, my insulin won't rise as fast as
it would in normal people, and that CRONites in general should eat
carbs only in small portions (e.g. < 100 calorie portions)?

I wouldn't conclude anything about your POSTPRANDIAL glucoregulation 
from your FASTING data. If you want to know about the former, go get an 
OGTT.

That said, the whole "CR-induced impaired glucose tolerance" thing 
happens in people with low fasting insulin, associated with low 
testosterone, thyroid hormones, and most robustly  IGF-1. Have you had 
the latter triad tested?
