"Regular exercise is known to increase DHEA production in the body.[31][32][33] Calorie restriction has also been shown to increase DHEA in primates.[34] Some theorize that the increase in endogenous DHEA brought about by calorie restriction is partially responsible for the longer life expectancy known to be associated with calorie restriction.[35]"
