Calorie-restricted diet keeps heart young

Portable heart monitors were worn by study volunteers who practiced calorie restriction and others of about the same age who ate standard diets so that scientists could measure their heart rate variability.
People who restrict their caloric intake in an effort to live longer have hearts that function more like those in people who are 20 years younger.
Researchers at Washington University School of Medicine in St. Louis have found that a key measure of the heart’s ability to adapt to physical activity, stress, sleep and other factors that influence the rate at which the heart pumps blood, doesn’t decline nearly as rapidly in people who have significantly restricted their caloric intake for an average of seven years.
The study is available online in the journal Aging Cell.
“This is really striking because in studying changes in heart rate variability, we are looking at a measurement that tells us a lot about the way the autonomic nervous system affects the heart,” says Luigi Fontana, MD, PhD, the study’s senior author. “And that system is involved not only in heart function, but in digestion, breathing rate and many other involuntary actions. We would hypothesize that better heart rate variability may be a sign that all these other functions are working better, too.”
Fontana
The researchers hooked portable heart monitors to 22 practitioners of calorie restriction (CR) who ate healthy diets but consumed 30 percent fewer calories than normal. Their average age was just over 51. For comparison purposes, researchers also studied 20 other people of about the same age who ate standard Western diets. Heart rates were significantly lower in the CR group, and their heart rate variability was significantly higher.
“Higher heart rate variability means the heart can adjust to changing needs more readily,” says lead author Phyllis K. Stein, PhD. “Heart rate variability declines with age as our cardiovascular systems become less flexible, and poor heart rate variability is associated with a higher risk of cardiovascular death.”
Stein, a research associate professor of medicine in the Division of Cardiology, has measured heart rate variability in a number of different groups, from older adults to those with depression. This study was her first experience evaluating heart rate variability in the group often referred to as CRONies (Calorie Restriction with Optimal Nutrition), but members of that group have been studied extensively by Fontana, a research associate professor of medicine at Washington University and investigator at the Istituto Superiore di Sanita in Rome, Italy.
Stein
“The idea was to learn, first of all, whether humans on CR, like the calorie-restricted animals that have been studied, have a similar adaptation in heart rate variability,” Fontana says. “The answer is yes. We also looked at normal levels of heart rate variability among people at different ages, and we found that those who practice CR have hearts that look and function like they are years younger.”
Laboratory animals with a restricted calorie intake tend to live 30 percent to 40 percent longer than those that eat standard diets. Many humans who practice calorie restriction believe they also will live significantly longer, but that won’t be known for several more years. Still, Fontana says much of his research suggests calorie restriction with optimal nutrition contributes to significant changes in people that are similar to changes seen in animals.
“In many of our studies, we have found that a number of metabolic and physiologic changes that occur in calorie-restricted animals also occur in people who practice CR,” Fontana says.
And he says the finding that heart rate variability is better in people who practice CR means more than just that their cardiovascular systems are flexible. He says the better ratio suggests improved health in general.
“But we can’t be absolutely positive that the practice of CR is solely responsible for the flexibility of the cardiovascular system,” Stein says. “People who practice CR tend to be very healthy in other areas of life, too, so I’m pretty sure they don’t say to themselves, ‘Okay, I’ll restrict my calorie intake to lengthen my life, but I’m still going to smoke two packs a day.’ These people are very motivated, and they tend to engage in a large number of very healthy behaviors.”

It's somewhere in here as well....

Thought you had passed that milestone a few decades back?
-
how many calories should i eat to live a long time?
-
Old news.

Almost there! :D
-
Old news.
Agreed, this is common sense.

The article says "calorie restriction", not "teenage polio victim thighs".
-
no shit- caloric restriction keeps everything young. Pro bodybuilders and weightlifters who bulk alot look so old cause of all the food they eat, not just the drugs. there is a reason I look 25 and not 19

is this the opposite of the reason kevin levrone looks 30 and not 48?

;D
Who luvs ya old man........? ;D
-
.
That was an interesting documentary on calorie restriction, intermittent fasting, and the effects it has on blood markers for various things and body composition.
-
Agreed, this is common sense.
I want it to be the good old days where everyone was fighting me on this! >:(
-
Who luvs ya baby........? ;D

But you are finally right. :D

what's better - 80 years as a BBer getting laid and props every day...
or 100 years as a 107-pound vegan getting punked and mocked every day?

kevin didn't eat much food at all actually, he even said it. 4000 calories in the offseason isnt much at all especially when its not very long in kevins case it wasnt anyways.....throughout his life he said he never had much of an appetite ate 2000 calories when he shrunk down half the year..., lots of fish, vegetables. jack daniels ;D aside......wasnt pounding sugar and red meat like todays pros, didnt eat much beef either except in MMM

Total bullshit study! So the average age would go from 77 to 97? So my aunt who just died at 94 and over ate all her life and drank a 6 pack of pepsi everyday would have lived to 114? Why do you believe these stupid fucked up studies? Hope that made you feel better.

You must be a Bible Literalist as well eh?

I just woke up. ;D

Stfu you stupid gullible asshole! Post a pick that isn't from 2005 and show how easy it is to be ripped. ::) eat less to lose fat yeah what a new novel idea.
-
a long life of constant starvation, that will take some discipline even if you wanted it

Abs looking good bro!!! Nice job as always!!

Same thing is happening on the Political Board. Our resident morons are now openly admitting the fact that our involvement in the Middle East is about resources, and strategic positioning.
Getbig has gone topsy turvy!!! :o

I love this quote. Maybe you need to start a double split and eat chicken and rice every 3 hours and we can all trade places. :D

Almost there! :D
I was expecting this from you:
"You bastard!"

This thread is nothing but poppycock propaganda meant to discredit the Johnny Falcon principles and sabotage his image as a respected Caucasian champion and ruthless small businessman and I will have no part in it. The man gives his time, money, blood, sweat, tears, and semen to this board and this is how you thank him.
Shame on all of you.

Caloric restriction doesn`t make you live any longer. It only makes you feel like life is dragging on because you are constantly hungry.

x2 And no one is ever in a good mood on an empty tum. Food is a pleasure; enjoy yourself.

Truth, my wife knows when I am hungry before I do. :D

I can't believe I'm going to disagree with getbig's professor emeritus. If your diet is designed to minimize hunger and you are hungry anyway then you'll be miserable. But if your diet allows some level of hunger then it can actually be kind of enjoyable. Hunger is a great motivator. In small doses it makes you feel alive. Everyone should feel a little bit of hunger every day. Once in a while we should feel a LOT of hunger (fasting).

Gotta totally disagree with ya. 'Course, at heart, I'm a total pig. If I didn't keep active and eating sensibly/well, I'd be as dissolute as Baron Harkonnen. ;D
