Re: what about fasting periodically, and/or overall CR?

[Guest guest]

There are two version of this here. Some as Dr Roy did fast for one or

two days a week, (Although I do not know what he did as his illness

progressed). Others do semi-fasting by eating one meal a day with an

occasional snack. I am considering combining the two in some way, but

first I continue my weight loss in preparation of surgery in a month or

two. I have moved from Obese to merely overweight and need to lose

another 20 lbs to get to surgery weight.

Hi Hermit:

If you are aware of studies in any kind of mammal which show that

fasting groups live as long as CR groups, please post a link to it

because it will be of great interest to everyone here.

Certainly fasting does have interesting biological effects - some

apparently very beneficial, others of quite uncertain consequence.

But I have never seen a study which showed that fasting EXTENDED

MAXIMUM LIFESPAN in any species.

CR, in contrast, has been shown to extend maximum lifespan in every

species so far tested (lots of them ....... yeasts, fruit flies,

worms, mice, rats, dogs, and no doubt others; and studies of monkeys,

ungoing now for twenty years but still incomplete, strongly suggest

the same is true for them also).

For me, fasting would be more convenient than consistent daily

caloric restriction. So if there is evidence that fasting is as good

or better than CR I would certainly want to see it.

The fasting issue was discussed here quite recently. No one at that

time offered evidence that it extended maximum lifespan.
