Not to be confused with starvation, which increases metabolism and therefore hastens death,
caloric restriction involves controlled limited calorie intake.
«The results seem pretty dramatic,» says Mark P. Mattson, PhD, a senior investigator at the National Institute on Aging in Bethesda, Md. «Even though the number of subjects in the study was not really high, they had really high, statistically significant improvements in their performance on the memory test,» added Mattson, who studies
caloric restriction and the brain in his role as chief of the Cellular and Molecular Neurosciences Section at the Laboratory of Neurosciences but was not
involved in Dr. Floel's investigation.
