Anyone know of a study/proponent of 'one day eating/one day fasting' quasi-CR...?

I've a friend who says he's heard of people doing it; but that's all I know:
I don't even know what it would be *called*...

Thanks!

Well, you've got The Warrior Diet, which advocates "fasting" for 16-18
hours. During that time you can eat some fruit, fruit juice, vegetable
juice. It doesn't recommend fasting for more than that. The book is
full of a lot of pseudo-science, not real hard data. "Clearing
toxins", and all that B.S. but nothing to back up the claim.

There was a study with mice in which they put some on calorie
restriction, and a second group fasted for a day then ate whatever they
wanted for the second day. Both groups showed improvement in ... well,
whatever they measure. Blood, body weight, etc. Don't know of any
study in humans.

Yes, that's the one. So if you're a mouse with Alzheimer's, that diet
is the ticket

But seriously, I was reading up on Roy Walford, one of the chief
researchers. He evidently is the pioneer of calorie restriction as a
way to extend longevity. He died in 1979 of ALS.

Calorie restriction is obviously not very workeable. (Just go to a
mall and look at the shoppers). But fasting a day and then over-eating
might be doable.

"Every Other Day Fasting"

Search for "EOD Fasting".
Also search PubMed for research by "Mattson M" (Mark Mattson).

This might be of interest to get you started:

Wolford did advocate fasting two days a week as a method of caloric
restriction, and there are studies showing intermittant fasting
prolongs lifespan in rats.

I have heard of a study in Sweden, leading to a diet promolgated by
Bill Phillips, a body builder magazine and supplement promoter.

The diet consisted of 2 weeks of caloric restriction, about 1800
calories a day for a 170 pound male, followed by deliberate but
nutricious overeating, no junk food. 3000 calories a day or more, at
least 1000 calories beyond ones caloric needs with workouts. It was
supposed to result in fat loss and muscle gain. I tried it for two
cycles, all I could manage. I lost 10 pounds, and as far as I could
measure it was mostly fat. My power did not decrease. The weight
change and body composition was permanent.

I've no idea how such a diet affects life extension, but the two week
fasting likely activated the sirt1 gene. In that metabolic state the
extra calories consumed for the following two weeks went into replacing
lost muscle, as after starvation, rather than into fat. But the body
kept on putting on muscle arter replacing what had been lost. That was
the body building angle.

I'd heard of him -- though it was actually in 2004 that he died, and he was
79!!

Alas, we can't tell much from one case: he might have had earlier, or worse,
ALS without his CR...

This was my thought! And what's more, I tend to have a kind of 'eating day /
fasting day' life at the moment anyway. Hence my interest...!

Check out the Yahoo group "fasting" at:
http://groups.yahoo.com/groups/fasting

"This group is devoted to intermittent fasting and its effects on
physiology and health. We expect that both practitioners of
intermittent fasting and scientists with an interest in the
physiological effects of intermittent fasting will want to join. The
founding members are both practitioners and scientists. We are
interested in the idea that intermittent fasting may be a preferable
way of obtaining the health benefits associated with caloric
restriction."

It's called intermittent fasting or alternate-day fasting. I and others
have posted studies on it here before. It's effective for M.S. I find
it beneficial for my autoimmunity - probably via the effect of mTOR
inhibition on regulatory T-cells. It tends to extend lifespan in animal
models, though not as much as strict CR. If I remember a chart posted
here some while back, unlike CR it does elevate growth hormone/IGF-I
levels, which may be one reason body-builders like it
http://www.pnas.org/cgi/content/full/100/10/6216/F2. It also boosts
ketones [PMID 16126250], which makes it good for epilepsy, juvenile
brain cancer and spinal trauma. It blocks mitochondrial ROS and
elevates SOD which makes it beneficial for a wide range of metabolic
disorders. I would encourage you to search through past postings on the
topic.
