Hello all.

The subject of CR has been something that has interested me for about

the past 5 years.

I have read some of the research, and it seemed that while early in

life was good, too early could have negative effects.

I resolved to wait until my 25th birthday, which would also give me

time to learn about any possible problems encountered by those

attempting this.

I'm not too concerned about the willpower aspect since hunger has

never been a big thing for me. I tend to eat what is available, not

have cravings, and if occupied with things, can sometimes forget to

eat for a couple of days or more (yes, I know, not healthy, just

absentmindedness).

My concern is with any potential negative effects. Studies in animals

have shown positive results with all sorts of species, but what things

have been tested?

Quality of life. Is there significant loss of energy?

Intelligence. Were any IQ tests run on the animals? I know the brain

is rather greedy in humans, demanding much heat, oxygen, and

nutrients. Is there a potential for a drop in IQ?

The advice for beginners indicates starting at current caloric intake

and slowly dropping. Unfortunately mine tends to fluctuate wildly.

Also, it *was* a little vague as to what point starvation becomes a

factor.

Has anyone on this list tested the limits? At roughly what percentage

of recommended body weight did problems set in?

Thanks for any answers! I'm very much interested in this, and plan to

start by that arbitrarily selected date unless evidence recommends

otherwise. (25th b-day is a little under a year away)

You certainly have given CR a lot of thought. Have you read Walford? All

the animal experiments are in his books. Check our files for information on

what to read such as our " bible " : Walford " s The 120 Year Diet.

Since you have a year before starting (if you decide to start) I recommend

you lurk (or post if you wish) on the list and monitor the posts to see if

CR is for you. This one year delay should also give you plenty of time to

access the archives of both groups. There is extensive information on

possible negative effects that some of us humans are definitely experiencing

such as: osteoporosis, low testosterone leading to reduced sex drive,

thinking and problem solving problems in some, and sharper thinking in

others, and related topics such as modified vs. extreme CR, and anorexia.

Unfortunately, most answers to the possible problems are not yet certain,

since we are the first humans in this experiment (unless you count the

Okinawans). If you have any more specific questions after reading Walford

and checking the files and archives, let us know, .

Hello Francesca,

From what I have gleaned in previous posts to both groups, wasn't

the osteoporosis related to low protein vegatarian diets prior to

people going on CR?

crsociety/message/20099

Also, I know there have been reports of osteopenia (bone mass

loss) as a results of CR but no osteoporosis as a result of CR.

crsociety/message/21095

The mental acumen issue seems to be related to too low of a protein

and fat CR regimen vs. carbohydrates.

I read this post and it also concerns me. Increased

fracture risk among animals on CR diet? With all

other factors equal? Same calcium intake? I've heard

high-protein diets can mess with one's calcium levels.

Any examination in these studies of the age at which a

significant amount of bone loss becomes evident? In

osteoporosis at least, it seems that by the time it is

noticed, it is irreversible.

This *does* concern me because I *do* have a fairly

light bone structure, and while I've managed to avoid

broken bones (well, p'raps the usual undiagnosed

stress fracture or two), my brother was notorious for

breaking them. Due to inherent defects in the bone.

Also, I practice kendo, which while it is fairly safe

as martial arts go, *does* involve a lot of abuse to

the feet and knees. It'd be a shame to have to give

it up. Quality of life matters too

Kyber
