Should I cut activity to reduce calorie requirement?

Dave said:

I was wondering I am taking too much activity. The first topic I read
up on the internet, about 10 years ago, was life extension via calorie
restriction.

I have calculated that I am using about 500 calories a day (100
calories a mile) in activity, and to stop my BMI going below 23 I need
to eat quite a lot, which may be over an optimal number of calories
for maximum life duration. Should I stop walking and get the bus?

Maybe I should exercise more intensively, but for a much shorter
duration.

What you read was very poor science. The studies were poorly done. The
"food" that the lab animals were fed was a lab concocted pile of [censored]
food components so that they could quantify the amounts of fat,
proteins and carbs. The food was not selected for its quality but to
ease quantification. And those animals fed the less of this nearly
poisonous [censored] food concoction lived longer not from the "benefits" of
a low calorie diet, but from the benefits of eating less nearly
poisonous nutrient deficient refined [censored] food.

Eat real food with real nutrition and stay away from highly refined
proteins, fats and carbs and you will live a long healthy life. Food
is nourishment. Without real nourishment you will live a shorter less
healthy life. Less nourishment may help if the rest of what you eat is
crappy poisonous foods, but in the absence of nourishment you will not
live very long or healthy.

Common sense buddy.

What about sitting in a deep freeze for say half an hour a
day. 90% of our calorie intake goes to keeping us warm.

Are there any studies that demonstrate a life span increase by
substituting those commonly used pellets with whole foods?

"Not as good" (rather than poisonous) I'd consider a common sense
hypothesis, for any reductionist pellet diet, based on the premise
that something beneficial or even essential could be easily missed
when designing a pellet.

The fact that we evolved to eat a certain diet doesn't imply to me its
optimality for longevity.

In any case, there are CR studies that are too old and predate any of
the pellet lab-food practice. A 1955 review (http:/pmid.us/14384511)
cites old experiments (understandably none from the future) in favor
of CR, some dating back to the beginning of the last century. It also
states concerning animal CR experiments conducted at the time:

"Actually in life span experimentation nutritionists have preferred
natural food stuffs such as meat, milk and whole grain cereals to
purified diets".

This will increase metabolism due to thermogenesis, unless you want
him to freeze himself to death.

Sorry, correction "below" should read "above" BMI of 23, since if I
get thinner people think I look ill.

Calorie restriction is still being publicised as a key to a longer
lifespan:
http://www.telegraph.co.uk/health/main.jhtml?xml=/health/2007/06/18/nosplit/halzheimers118.xml
"Calorie restriction has long been known to enable animals, and
possibly humans, to live longer."

So the question remains and there is a new one: "Where are the studies
of people who lived to 100 and stayed healthy? What did they do
right? (besides having their parents)" I would pay GPB 12.99 for a
book with this knowledge.
