In a study conducted by the Proceedings of the National Academy of Sciences (PNAS), scientists discovered that descreasing daily caloric intake by 30% could improve memory and cognitive function. The quality and duration of life also seemed to be increased.
The study followed three forms of diet amongst 50 people approximately 60 years old. The first diet decreased daily calorie intake by 30%, the second included eating large amounts of saturated fat and the final one allowed for the subjects to just continue their normal diet.
At the first check up, about three months later, all parties seemed to respond similarly mentally. At the conclusion of the study, though, those who’d given up 30% of caloric consumption showed an increase in memory function. Scientists continue to meddle with certain drugs that could mimic this reaction.
