The Amazing Ways Of Life: "Experts theorize that limited access to energy alarms the body, so to speak, activating a cascade of biochemical signals that tell each cell to direct energy away from reproductive functions, toward repair and maintenance. The calorie-restricted organism is stronger, according to this hypothesis, because individual cells are more efficiently repairing mutations, using energy, defending themselves and mopping up harmful byproducts like free radicals.
“The stressed cell is really pulling out all the stops” to preserve itself, said Dr. Cynthia Kenyon, a molecular biologist at the University of California, San Francisco."
