> Trying to maximize your years on this earth? Only known way is to calorie restrict. Like extreme calorie restrict. Say, around 1000-1200 cals a day.

Has this ever been proven to work in humans? I know it has been found to be true in rats, non-human primates, etc, but humans already have abnormally long longevity for mammals (http://skeptics.stackexchange.com/questions/5701/does-every-...). The types of changes calorie restriction triggers in other animals may have already be part of a regular human.
