Caloric restriction and longevity in primates study

For 25 years, the rhesus monkeys were kept semi-starved, lean and hungry. The males’ weights were so low they were the equivalent of a 6-foot-tall man who tipped the scales at just 120 to 133 pounds. The hope was that if the monkeys lived longer, healthier lives by eating a lot less, then maybe people, their evolutionary cousins, would, too. Some scientists, anticipating such benefits, began severely restricting their own diets.

The results of this major, long-awaited study, which began in 1987, are finally in. But it did not bring the vindication calorie restriction enthusiasts had anticipated. It turns out the skinny monkeys did not live any longer than those kept at more normal weights. Some lab test results improved, but only in monkeys put on the diet when they were old. The causes of death — cancer, heart disease — were the same in both the underfed and the normally fed monkeys.
One of the downsides of the Internet is that it allows like-minded people to form communities, and sometimes those communities are stupid.

This experiment is akin to putting two plants in a dark cupboard, watering one but not watering the other and watching them both die.
Then concluding that there is no connection between water and healthy plants.

It also shows that taking a group of monkeys and mentally stressing them, by having them wonder if they will ever get fed enough, will cause them to die as early as monkeys who eat more but don't have that stress.

it is pretty fuct up to design studies where the fundamental conditions are inimical to a healthy lifecycle.

I predict that inside of 48 hours you will see a story based on this with a headline letting you know how people who restrict calories don't live any longer - translated as you should simply eat anything you feel like and not worry about it.

I find the CRON people interesting - would actually like to see some well-designed studies on this. Aren't some of the folks who eat this way more sensible than eating what was, I believe in this study, the equivalent of 800 calories daily? In the documentary linked to over here - http://irongarmx.net/phpBB2/viewtopic.php?f=2&t=221959 - the guy they featured didn't eat that much less than the reporter, for instance.

I viewed some cron website a couple of years ago. They had pictures of several of their adherants, both
men and women.

The people with pictures on that site just did not look healthy or happy.

Pretty much. I've had issues with food for a while and tend to be on the restricted end of things in a sort of "involuntary" way. Not anorexia but definitely below what would be considered maintenance level for the amount of activity I do. Kind of "if I run/ride X and eat Y and that gives me Z bodyweight, running/riding more than X and eating less than Y will be even better".

I always end up miserable, cranky, tired, sore, and hurt. I think the key, as always, is moderation. Eat enough to fuel a healthy bodyweight. Try to eat WFR when possible. But DO NOT sweat it when the opportunity comes along to go out and have a good meal and some beers with friends.
I don't have a lot of experience with vampires, but I have hunted werewolves. I shot one once, but by the time I got to it, it had turned back into my neighbor's dog.
