Many mechanisms have been proposed to try to explain why this calorie restriction diet increases life span. Studies at the molecular level have shown that many genes in the sirtuin class of the DNA, including SIRT1, SIRT3, and SIRT4, create enzymes that increase the activity of the mitochondria and slow the cell's aging process. There have not been sufficient studies to conclude if humans on calorie restricted diets will live longer, but introduction observations of the physiological changes caused by calorie restriction show that life-lengthening effects should also be evident in humans.Calorie restriction is an approach, an everyday life choice when practiced by humans that has been proven to increase healthy and highest life span in rodents and primates. Certain animal studies that have been done over the past two decades have shown up to a 40% increase in optimum life span. Calorie restriction also provides many secondary health benefits, such as a greatly lowered danger for many...
