Discovered about 70 years ago, CR involves reducing the calorie intake of an animal by 30-40 % compared to its normal caloric intake. Science reporter pdf 2018 It is thought to lower
metabolic rate and cause the body to generate
fewer damaging free radicals. CR delays or
prevents age-related diseases and extends lifespan in species ranging from yeast to primates. science reporter in hindi Evidence that Calorie Restriction
(CR) retards aging and extends median and
maximal lifespan was first presented in the 1930s by McCay et al. Since then, similar observations have been made
in a variety of species including rats,
mice, fish, flies, worms, and yeast. sciencereporter in hindi

studies in monkeys also suggest that the mortality rate in calorie-restricted
animals will be lower than that in control subjects.
