CR, Fasting, Cell Proliferation, Cancer

[Guest guest]

Hi folks:

Someone sent me the pdf of this study a few weeks ago (yes we all

know who! ty!) and I have only just gotten down to reading it. It

looked at the cell proliferation effects in mice of various forms of

CR and fasting. It is not easy reading, but if I have it right, with

their mice they found that:

A) At 33% CR it doesn't make much difference whether fasting is also

involved or not.

At 5% CR, adding fasting to the mix - feeding only three days a

week, MWF in this case - had a sizeable beneficial effect.

C) Among the groups of mice they studied, those that appeared to get

the greatest cancer-protection benefit were the ones which started

out at 5% CR and went to 33% CR later.

But of course this was mice. .....................

I have added it to the studies listed in the files here.
