this is nothing new - the theory that a low-calorie diet slows aging has been out there for quite a while. It looks like many of the people, like the Hunza, who used to become very old, had low-calorie diets.

And I think there have even been studies on  humans too, here just an example.

Low-Calorie Diet May Lead to Longer Life - New York Times

A low-calorie diet, even in people who are not obese, can lead to changes in metabolism and body chemistry that have been linked to better health and longer life, researchers are reporting.

The findings lend support to the theory that eating less, long known to prolong life in rats and mice, may do the same for people, by preventing heart disease, cancer, diabetes and other diseases, and by slowing aging.

The notion that going hungry could be the fountain of youth has captivated scientists and the public. Calorie restriction, the scientific name for a regimen high in nutrients but low in calories, is the subject of intense research, and some people have already begun trying it on their own.

There is a Calorie Restriction Society with members all over the world, and its president, Brian M. Delaney, estimates that the people experimenting on themselves number in the thousands.

in some of the first health food shops in london, mid sixties, you could buy little dried hunza apricots, reputedly high in natural silver. they were unbelievably delicious, we used to crack open the seed and eat the kernel, for the laetrile.

i got curious about the hunzas, and learned they would happily walk every morning 5 miles to their fields and work there all day.

tough people, serious survivors.

i eat less in a week now than i ate in three days growing up, and am much healthier for it.

the reasons it's so un-PC to criticise fatties is that they just eat more if you do.

besides, the problems people carry around that you can't see are much worse than the ones you can.

a government that cared about its people would ban junk food, for its effects on future generations, and the gene pool in general, as well as the horrendous environmental degradation it causes.

i heard also a possible apocryphal story that prisoners in the concentration camps had no tooth decay, and that the reduced diets and greater reliance on wholegrains during the war led to much less sickness, that then returned to 'normal' afterwards...

I haven't heard about the concentration camps, but read about various reports of people being healthier during war time, because they ate reduced calories and fat.

And now that I think about it, that is amazing as during the war people must have been under tremendous stress and despite of that they seem to have been healthier.

Well, I guess it all depends on the war and the camp.  I've heard stories that people starved to death in places like Auschwitz and Leningrad.  Like, A LOT of people.  Apparently lack of food can cause death in some people...

Now, let us please return to our sanity.  Thanks.

point taken poemless, it's too easy to lose perspective sometimes.

what is amazing is how many people didn't starve to death, considering the conditions. the ability of the human body to stay alive notwithstanding the cruelty, with no reserves, negligable nutrition, and bitter cold beggars belief.

the fact that they had less tooth decay is relatively trivial, yet curious just the same...
