Hi folks:

I was reading p 78 of 'Beyond' again on the weekend. It only seems

to mention the problem of an excessively large drop in calories at

the initiation of CR. It does not discuss, at least not in that

section, a problem of an excessively low final level of caloric

intake, when established at targeted weight.

Does anyone know of any place Roy discussed, in 'Beyond', or

elsewhere, the latter issue?

>>>

On page 230, in the section " What calorie level to settle on " :

" If you change from the typical American high-fat diet to the diet

described in this book, you are apt to lose weight faster than

planned. That's all right for the first three to six months; it will

encourage you, but then you must slow down. Remember that animal

studies indicate that crash diets leading to rapid weight loss are

counterproductive: they *shorten* life span. "

There's a discussion on pgs 50-51 that is somewhat relevant. ....ending

with: ... " So what counts is not the absolute weight or the absolute degree

of leaness, but the weight relative to the set point of the....individual. "

On page 227 : " bodyfat should not be allowed to be below 5% in men and

10-15% in women. "

A 5'9" man aged 90 at 155# needs 1295 +200 kcals for just routine up and around.

I think 1500 may be a little "lite" for most men.

Here's an article on preventing the flu throughexercise and diet. Of interest to the topic at hand is this excerpt:"Eat enough calories. When intake dips too low, the immune system doesn'tfunction at optimal levels. What's too low a calorie count? Nieman and hiscolleagues have found T cell function is suppressed in women who eat lessthan 1,300 calories per day. No similar studies have been done in males, butNieman estimated 1,500 calories or above would be a safe level for men."

Anorexia is caloric restricton (CR) without optimum nutrition (ON) or

even adequate nutrition (AN). Diets low in protein prevent the body

from regulating the production of hormones (which are proteins

themselves). Diets low in fat damage the brain and nervous system.

The link below from the University of land School of Medicine has

some information about this medically recognized form of Extreme CR.

Neurological Problems

People with severe anorexia may suffer nerve damage that affects the

brain and other parts of the body. The following nerve-related

conditions have been reported:

* Seizures.

* Disordered thinking.

* Numbness or odd nerve sensations in the hands or feet (a

condition called peripheral neuropathy).

Brains scans indicate that parts of the brain undergo structural

changes and abnormal activity during anorexic states. Some of these

changes return to normal after weight gain, but there is evidence that

some damage may be permanent. Still, the extent of the neurologic

problems is unclear, and some studies have been unable to determine

specific mental problems associated with anorexia.
