What is the life expectancy of someone with CR?
Extrapolating the data about lifespan extension and CR obtained in mice to humans, we would predict that the mean lifespan could go from 75 to 90 years and the maximum lifespan from 120 to 150 years with CR.
What is a CR mimetic and how could it be important?
It has been proposed that CR mimetics should have the following key features: (i) they should mimic the metabolic, hormonal and physiological effects of CR; (ii) they should not significantly decrease long-term food intake; (iii) they should activate stress–response pathways, as observed in CR, and protect against a …
Which drugs mimic the effects of caloric restriction and have been found to increase lifespan in mice?
The newest study, published in the February 27 Cell Reports, found that SR1720 extended the life span of mice on a standard diet by about 9 percent. They also confirmed their earlier work indicating that the compound extends the life span of mice fed a high-fat diet.

How does rapamycin increase lifespan?
The overwhelming evidence suggests that rapamycin is a universal anti-aging drug – that is, it extends lifespan in all tested models from yeast to mammals, suppresses cell senescence and delays the onset of age-related diseases, which are manifestations of aging [discussed by me in [148,149,158,192].
