Info sought on later life onset of CR

[Guest guest]

From what I have read in the medical literature, it is unclear to

what it the maximum age at which a person may begin caloric

restriction and still have a reasonable expectation of an increased

maximum lifespan.

Can anyone direct me to some good resources on this, including

perhaps a section of these messages that may have dealt with this

very question?

Hi Physics,

I'm not sure if the topic has been covered on this list, but the other more

science-oriented CR listserv did discuss this extensively four or five years

ago.

Walford talks about it a bit in his _Beyond the 120 Year Diet_, and I think

the lab evidence with rodents pointed to benefits even late in life, but

shortly after puberty (or before maturity) had the greatest life-extension

benefits. However, this came at the cost of higher mortality in very early

life and reduced body size. As a result, Walford recommends CR only after

having become fully grown, and the extension of maximum lifespan in rodents

even well after reaching maturity are still quite remarkable.

As a worst case scenario, CR late in life will at least offer benefits with

preventing diabetes, cancer, heart disease, and stroke... Even if it

doesn't extend " maximum lifespan, " it could very well increase the length of

time one's around under that normal cap of 110 or so...

Cheers,

Hi All,

From the main list new web site at:

http://www045.heronetwork.com/

you can go to General information at:

http://www045.heronetwork.com/modules.php?

name=Sections & op=listarticles & secid=3

and then Compelling Graphs of CR Benefits at:

http://www045.heronetwork.com/modules.php?

name=Sections & op=viewarticle & artid=12

which shows that " A postive linear relationship is observed between

the duration of CR feeding and the maximum lifespan recorded in

rodent species. "

Cheers, Al.

Thanks for the responses to my questions....

I have been out of state recently, or I would have responded sooner.

I am now absorbing as much practical information as I need to ease

into a CR diet. I appreciate the existence of this group.
