Restricted calorie diets don't appear to extend lifespan

[EasyEJL]

It was originally shown in fruit fly studies that by cutting calories to 30% of what was considered normal maintenance you could achieve significant lifespan increases. This long term 2nd study on rhesus monkey appears to show that it is not the case in the primates

Invalid Link Removed

There was a prior study that showed lifespan increases in monkeys, but that study had a list of flaws about as long as the American Heart Association's diet studies.

It is interesting although not totally surprising that monkeys who were close to normal weight that were put on the -30% diet when they were older did see some blood marker improvements but it did not come with an increase in lifespan.

Starving monkeys for 25 years? :worried: Not cool. Especially for a negative result.

What is the maint cals of a fruit fly? .00000001 cal? Haha

I actually sat in on a seminar from one of the lead researchers in this field and was required to type up a 2 page summary/review of her lecture and all present studies. I'll post it up when I'm at the right computer.

mind you this is the second set as well, with the earlier sloppy study showing positive results.

She get into sirtuins, ampk, ppar's and all that good stuff? Or just calorie restriction itself?

I'd like to see someone *cough coop* start a thread with some good research pieces on AGEs. I can't quite bring myself to only steaming and boiling foods so far, but I keep pondering it.

Kick-ass. It's a very fun subject, one of my qual proposals was on Sirt2.
