I would like to live 100+ years. I mean yes their is a damn good possibility that the world will suck but at the same time technology changes so rapidly that I am very interested to see what will be around in that time. Also I do the 16 hour fast eat for 8 cycle and I deffinatly don't eat a miserable amount of food.
Your life can end by a simple car crash.
This obsession with longevity is too much.
Personally I'd rather live 10 years as a lion than 100 years as a sheep.

There are a lot of factors that can have an impact on longevity. Stuff that is so bad for us that the less the better like polyunsaturates, junk grains, and the like. Humans cook their food which means that we have tons of cellular protection against reactive oxygen species (we really really do), humans consuming these low calorie diets will almost certainly be nutrient deficient, which doesn't help anyone, and we need those nutrients for recovery and defense against bad stuff.
methionine, tryptophan, and cysteine restriction produce huge results in longevity, and so does IFing that amounts to the same amount of total calories. The very high fat deal is promising as it constantly supplies the material for repair, and collagen proteins like gelatin can be in a part a replacement for the muscle meat. We can take various supplements like alpha-lipoic acid to regenerate glutathione and we can get a lot of really useful stuff from ruminant animals like l-carnitine, CLA, and such.
So I suspect that while caloric restriction may have some uses, perhaps the better path would be to mimic what is good about it without actually starving ourselves. Body hax, if you will. Grokologist will likely have some good stuff to say about this in the future.
I kind of agree with Matt stone that overfeeding is a very useful tool temporarily. There are cases of mitochondria in mice being genetically engineered to become more efficient and do more with less energy while producing less ROS. So if we can mimic that, possibly with a temporary over-feed, we will be better off for it.
That's mostly speculation but my point is that caloric restriction is not necessarily necessary.
edit: and if we end up restricting calories it will be because of such efficieny and good leptin signaling rather than some maniacal restriction scheme.
