Re: An observation on activity

[Guest guest]

Hi Ray:

Welcome!

I am fairly sure that modest to moderate exercise is beneficial.

Specifically, it helps 'rectangularize the curve', the meaning of

which you will certainly understand if you have read Dr. Roy

Walford's 'Beyond the 120-Year Diet'. It will also make you more

capable of doing the things you will want to do when you get to old

age.

HOWEVER, it does not contribute much to **weight loss** - if that is

what a person is looking for - unless they do truly humungous amounts

of it. And humungous amounts of it, by definition, require large

amounts of calories which sort of runs counter to the idea of caloric

restriction.

For example, many (most?) people who believe they 'need to exercise

to lose weight' would have a hard time walking for any length of time

faster than three miles per hour. At that speed burning off one

pound's weight in calories requires walking about 70 (yes, seventy)

miles.

So the question for someone wishing to lose twenty pounds is: " Which

would you find easier: Walking 1400 miles? Or eating a bit less

each day instead? "

My congratulations go out to those who choose the exercise. They

have more guts than I have. But their maximum potential life span

would be lengthened by restricting food intake, and it (maximal

lifespan) will not be lengthened by the exercise.

I have exercised a fair amount over the past fifty years and I

suppose I am now 'fitter' than I would otherwise have been without

it. But as Dr. Henry (cardiologist) asserted in 'The

Exercise Myth' ........... " fitness has absolutely nothing to do

with health " .

Well, there was a recent study of elderly adults (average age 75),

http://jama.ama-assn.org/cgi/content/full/296/2/171

in which the death rate of the 1/3 least active was DOUBLE the death rate of the

1/3 most

active. I strongly suspect (without any proof) that this would hold true even

for a group of

calorie restricted humans.

My target is to spend at least 3 hours a day on my feet and moving (but I don't

exercise to

the point of shortness of breath).

Hi Ray:

Thinking about this a little more, it is probably more accurate to

say that exercise rectangularizes the survival curve, and so

increases average lifespan, but reduces maximum potential lifespan in

proportion to the extra number of calories required to fuel it.

This is based on the probably-fair assumption that maximal potential

lifespan is inversely related to average caloric intake.

(Naturally, assuming adequate nutrients)

Difficult to determine cause and effect.
