I've been wondering this for quite a while now, it seems to me a very logical choice to practice calorie restriction, especially if your goal is to 'live forever' or live much longer than the normal human lifespan. As far as I can tell there are very few here that do CR, but I assume that quite a lot eat a reasonably healthy diet. Have anyone here considered doing CR before, and if so, what stopped you? Do you think there is still not enough evidence for human CR? Are you not yet impressed by CR rodent studies, especially the primate studies (which are now showing major differences on the outside (appearance http://www.imminst.o...=237&t=15167&s= ) and inside. From what I can see, quite a few CRers who have been doing it for an extended period of time look quite young for their age, and the studies done by Fontana at WUSTL show that CRONies have remarkably low risk from all major diseases, to the point of having almost 0 chance of developing them, even though the age range is big, up to 80+ years of age.
The single most well studied and effective way to extend maximum lifespan in all species, yet hardly anyone from Imminst has implemented it. Just seems a little odd thats all
Remember there are only ideas and theories on why CR won't work in humans, there is no credible evidence actually showing it doesn't work. The okinawan's although were supposed to be a good model for CR, now there is evidence that their CR was mild, and their calorie intake has kept increasing since the 1960's and haven't been CR'd all their lives. And we know just how rapid metabolic changes can happen when going from low calorie to higher calorie and less nutritious food. So the CR effect in Okinawa is very underestimated in its ability to extend lifespan.
