mea culpa

[Guest guest]

It's been called to my attention that I may have offended some members when

I said below that moderate CR is " promoted on this list " . I apologize to

any that were so offended. We do not have an " official " policy on this and

of course everyone must find their own path. I should have specified that

it was " me " the support list member giving my opinion, not me the moderator,

or me the " authority " figure .........

What I was calling your attention to was Suz's notice of a passage that the

longest lived rats are somwhat underweight but not extremely so - IOW a

testimonial from the man himself that extreme CR ain't such a hot idea. And

by inference that moderate CR (which is promoted on this list) IS the way to

go...........

Sure the body attempts to adjust in some of the ways you mentioned, but most

often it adjusts by slowing the metabolism. What's the point in 'living

longer' if you have to be 'less active? " . 'Nuf said.

Well, actually you're right, it wouldn't 'limit' one's 'ability' to expend

energy upon demand, however it certainly would affect efficiently your body

converts nutrients to energy. Either way, to me the result sounds contrary

to the whole point of CR.

[Guest guest]

Not so.

1. if you eat “less that you need”

your body adjusts by (a) reducing highly active metabolic tissues ( using injected

calories more efficiently and © becoming less active. You might claim that

these effects are not “healthy”, but the evidence shows otherwise. In

other words: homeostasis can be maintained at different points. The $64K

question is which point. The evidence suggest that you get to this point by

eating less. How much less? Well… Depends whether you’re “moderate”,

“extreme” or “light” J

2. I agree that eating less than the SAD

diet will benefit health (and I heartily recommend it), but still, (1) holds.

Micky.

From a newcomer/observer to this list:

If CR stands

for caloric reduction and, in the context of what Dr. Walford

and other

scientists/doctors have hypothesized, its objective is enhanced

health and

longevity, there should be no such thing as " moderate CR, "

" extreme

CR " " CR-light " etc. The fact is, physiologically the human

body

requires a

certain amount of calories for homeostasis. That amount

(basal/resting

metabolic rate) is based on several key factors, one of which

is activity

level. Most of us, particularly in American society, consume way

above that

amount, so practicing CR can be achieved merely by eating more of

the

" right " things and taking in less empty calories. Others may

choose to

go a bit

farther, limiting calories even more, however, you still have to

remember the

basal metabolic rate. If we don't meet that need, enhanced

health and

longevity would not only be compromised but highly unlikely.

Whoa ~ does slower metabolism = less activity? I wouldn't think that one's metabolism dictates one's ability to expend energy upon demand, but then I never really thought about it. Dave Noel
