Can a very low calorie diet extend life, and if so how? Animal studies seem to say yes, and one scientist is trying it out on himself.

Just as human beings show signs of stress and abnormal behavior when kept in captivity (Goffman 1961:11), so these animals often responded to crowded, confined conditions by exhibiting highly aggressive and sometimes pathological behavior. But many biologists assumed that the behavior of these imprisoned, neurotic creatures was the same as it would be under natural conditions.
The significance of the difference between these studies becomes clearer in the light of an experiment carried out with peaceable, forest-living baboons in Uganda (Rowell 1967). A troop of these baboons was captured and caged so that they were forced to live in crowded, confined conditions. The result? Fights and aggression became common, and a rigid dominance hierarchy emerged. Thus, as Pilbeam says, the baboons that were first used as models for early hominid society "probably were under stress, in a relatively impoverished environment, pestered by humans of various sorts. The high degree of aggression, the hierarchies, the rigid sex-role differences, were abnormalities"(1972:66).
It makes me wonder what role stress and aggression would play in the longevity of those calorie restricted animals?
It also reminds me of the psychology experiments I read about in psychology textbooks were rats and monkeys were either shocked or had electrodes implanted in the region of the brain associated with aggression in order to stimulate aggression. I thought I read somewhere recently where scientists were successfully breeding rats for an aggression trait.
Maybe if the Alliance for Aging Research obtains the substantial increase in funding it seeks for antiaging research it could do more complex animal experiments involving stress and aggression.

If they really did live longer, I'd think the benefits of CR would have become widely known centuries (or at least decades) ago.
You don't have to look hard to find quotes by historical figures about eating less.

I've been pondering something about calorie restriction. I realize that the effects of CR in controlled experiments with lab animals have been known about in the scientific community for quite some time. However, I'll bet most of the general population still doesn't know about CR.
Most of the population do know and have done CR lots of times, but its mostly obesity avoidence, nowhere near the degree needed to have any significant effect on longevity, also dieters don't stick to life long calorie restriction either.
But if CR was truly a human life extender, wouldn't it have become widespread common knowledge ages ago?.
There is some evidence of life extension in okinawa from their CR, but they were only really CR'd until the late 1960's, when they calorie intake averaged around 1600k/cal day. It's now somewhere around 2000k/cal a day. Plus they're quite short people also. In some villages in okinawa there are a high number of cetnenarians, one place equals 170~ centenarians per 100,000. I think okinawa as a whole went upto something around 50 centenarians per 100,000 (population 1.3 million) compared to americas average of around 6-10 per 100,000. If you read some of the interviews from the elder okinawans you will see that they say to eat less food. Okinawa though underestimates moderate to CRs life extending effects because they were not CR'd througout life, not everyone would have been CR'd, some of the elders are actually deficient in various minerals and vitamins.
Calorie Restriction is more than just being thin, or obesity avoidance, it extends the lifespan of rodents to un-natural levels. Have a read of Michael Rae's paper in response to aubrey de grey.
Jay Phelan an evolutionary biologist calculated that all calorie restriction would offer is around 2 years in life expectancy for the average male. I find this prediction absolutely absurd.
A recent hawaii study showed that if one avoids all 9 risk factors the they have around a 70% chance of reaching 85 years Also Seventh day adventist men typically live around 10 years longer than other americans. So SDA have much longer life expectancy, and by more than 2 years (which phelan predicted for CRs L.E) without the help of calorie restriction too. The average SDA male has a BMI of around 24-25, compared with CRers who are around BMI 19
You look at the data coming in about "CRONIES" health, you will see that people who do CR have all the characterists usually present in centenarians. Whether it be low cholesterol, larger LDL particle size, protection against age associated increase in inflammation, high insulin sensitivity, high adiponectin, low glucose, low bp, lower wbc. The risk factors for CRonies getting diabetes, heart disease is extremely low... plus humans die much less often from cancer than do rodents. Immunity is also preserved in every animal on CR. I'm not even convinced that *GENES* account for more 25% of longevity, it's probably less.
CR IS the most EFFECTIVE way to extend lifespan in all species tested, it primes the organism for long life. If anyone is going to have a very high shot at reaching the 100 mark it is a CRONie. We all have longevity genes within us, we just need to express them

Calorie Restriction started at middle age extends lifespan of mice. Videos of the mice from both groups are included in the video, and the CR mice appear to be very active in comparison to the ad lib fed group.

Thanks for posting that last one. I find BioMarker very interesting and have looked at geneessence also.

Calorie Restriction Fox News (CR Way)
Mike Linksvayer, a 36-year-old chief technology officer at a San Francisco
nonprofit group, embarked on just such a diet six years ago.
Eat Less, Live Longer?
Have we found the fountain of youth? Scientists are discovering ways to make
animals live dramatically longer through calorie restriction - a diet that
requires eating at least 30 percent fewer calories than normal.

I guess I'm saying that if CR significantly pushed the boundaries of normal human lifespan, we would already know about it. We'd not only know about it, we'd all be practicing it.
We don't know for sure if people in the past practiced a CR like diet though. Those that did (the poor) likely did not get enough nutrition. In ancient Greece they did emphasize a healthy diet for longevity, but the long lived societies were called macrobiotics and their diet is nothing like CR.

By the way, Matt, those two pictures of yours in your blog, you really do look older in that picture at 19! Incredible really.
Dmitri 06 Oct 2008
This is a fantastic video. They both look so young and full of energy.
Meredith doesn't look like the average 61 year old, but she still looks old and Paul looks like he's in his 50s which he is; I assume that's because they started CR in their mid 40s.

Paul is 60 years of age, and I believe Meredith is about 62. And yes they started CR late 40's.

Thank you! I know it's amazing, I was quite shocked when I came across the picture again to be honest. No wonder why I got all the comments about how young I look at college 'after' I started the CR lol. I'm hoping the results will be quite dramatic by the time I reach 30-40 or so, I expect they will be.

I just watched that, and what amazed me the most was that 110-year old Okinawan woman. Honestly, she didn't look much older than my grandmother, who's 70.Video with a small section on CR. Paul and Meredith are in it once again, also a small part on Okinawans too. The 110 year old okinawa is looking very good for her age. Also Meredith and Paul are in the video, they mention their ages and Paul is 60 and Meredith is 62!
