Re: if exercise speeds things up, is that compatable with CR philosophy?

[Guest guest]

We have a file called: " How much exercise? " under " CRON SCIENCE. That and

reading the portion about exercise in " BT 120 Y Diet " will answer your

question.

I'm not a CR veteran, nor a scientist, but I can tell you how I personally

resolve this issue. I've decided that the benefits of CRON are not worth

risking by doing a lot of calorie-burning exercise like running, or

aerobics.

I have a very active lifestyle to begin with, including lots of unavoidable,

brisk walking every day (1 hour+), and other forms of physical exertion. If

my life were completely sedentary, I would be sure to add exercise of some

kind to prevent atrophy, but not to burn calories. Even with an active

lifestyle, I engage in sports, and also do light weight training, but those

are purely for Quality of Life reasons, and I consider them to be a

worthwhile sacrifice in the personal game of " trade-off " that we all make

with CR.

The answer to your second question is really up to you to decide, but I feel

pretty safe in saying that, from a CR point of view, that treadmill stuff is

probably counterproductive.

Now I'd just like to take this opportunity to editorialize a bit. My

opinion is that every CRONie should be doing strength and, if possible,

flexibility training. These are not big calorie burners as long as you

don't go hog wild, so the CR impact is small, but the effect on your

well-being is enormous. When I started CR I was worried about " wasting

away " , but, while I've lost a lot of weight quickly, I've actually added

muscle and strength in my upper body all the while maintaining an average of

1,500 kcal/day.

My opinion, based on the science, is that aerobic exercise doesn't

increase your metabolic rate significantly. So what I think is

optimal for CRers is to exercise aerobically for no more than 20

minutes a day to burn up all your blood glucose (which averages about

15 grams I believe). That would only take up about 45 calories a

day. Past that point, you'll be burning fat, which is unnecessary on

a long-term CR diet. If you're already active to the tune of 20 mins

total a day and comfortable with your body composition, you may not

need to specifically do anything more.

Weight training is a different issue. I feel the safest way to deal

with this exercise is to keep it low-moderate and limit yourself to

increasing only protein to deal with the increased metabolic rate.

That way your body will know the appropriate amount of protein to

convert to glucose as needed.

And if you're addicted to the drugs released during exercise, well

that's an entirely different issue. :-)

Hi folks:

FWIW it seems to me the point about exercise is the following.

There is a survival curve. Where the lower right corner of your

particular survival curve is (probability of your survival) depends

overwhelmingly on your caloric intake.

For exercise, though, no matter what the location of the lower right

corner of your survival curve, an appropriate amount of the

appropriate kind of exercise is one of a multitude of factors that

can contribute to rectangularizing your curve.

(Of course it would be nice if we could define the 'appropriate's

above).

It seemed to me that Walford took huge amounts of exercise.

Especially when considering his age. A lot more than I am prepared

to take on, or even capable of.
