The original observation was with low calorie. Doing it low carb is the

It doesn't work with monkeys either.

I'm not sure what you mean here. Calorie reduction works for monkeys.

Calorie reduction doesn't work to extend life in monkeys.

Thanks. So we know that low carb is beneficial compared to at least the
Standard American Diet and likely to an assortment of other plan types,
but we also know that low carb does not increase life expectancy in
monkeys. So far we don't yet know if low carb increase life span in
monkeys but the initial results suggest it doesn't.

A few years ago Discover magazine had an issue dedicated to longevity.
Several of the articles suggested that low thyroid levels were one
aspect of longevity. Comparing the thyroid levels of humans against
many other species should show that - It's more than 10-to-1
dogs-to-humans. Years ago I've read studies that show that both very
low calorie and very low carb diets reduce T3 output. Probably a reason
or the reason so many who extend Induction who also don't have 80+
pounds to lose stall when doing so. And probably a reason that those
few Inuits who still live the traditional hunting lifestyle on the ice
don't continue to lose.

Discussing this with folks on sci.life-extension there were claims that
reducing a specific amino acid does more than reducing carbs. I haven't
dug into the studies or data on that so I don't know how it works.
Looks like low protein, mildly low carb, high fat might work for
longevity. That's not inconsistant with the weight loss versions of low
carbing but it's different enough to expect that the main thing we're
importing to such a process would be lack of hunger.
