Rapamycin appears to have a similar effect to restricting food intake,

Rapamycin extended the animals' expected lifespan by between 28% and 38%. But don't try it now. Scienties and experts in ageing described the study as "exciting". "It is especially interesting that the Rapamycin was effective even when given to older mice, as it would be much better to treat ageing in older people rather than using drugs long-term through life." However "In no way should anyone consider using this particular drug to try to extend their own lifespan, as rapamycin suppresses immunity. "While the lab mice were protected from infection, that's simply impossible in the human population.”
