Calorie Restriction CR without malnutrition is the most powerful nutritional intervention that has consistently been shown to increase maximal and average lifespan in a variety of organisms, including yeasts, worms, flies, spiders, rotifers, fish and rodents [ 1 - 7 ].
Far from merely stretching the life of an old, ill and weak animal, CR extends longevity by preventing chronic diseases, and by preserving metabolic and biological functions at more youthful-like state [ 6 - 12 ]. However, whether or not CR with adequate nutrition will significantly slow aging and extend lifespan in non-human primates, and most importantly in human beings, is not yet clear.
Currently there are two ongoing randomized control studies on the effects of CR without malnutrition in Rhesus monkeys: the Wisconsin National Primate Research Center WNPRC and the National Institute on Aging NIA CR monkey studies.
The WNPRC study, started in , involves 46 male and 30 female rhesus monkeys [ 24 ]. The NIA controlled trial, started in , involves 60 male and 60 female rhesus monkeys [ 25 ].
Baseline characteristics of the WNPRC and NIA monkeys are recapitulated in Table 1. Importantly, regardless of significant differences in diet composition and study design between the 2 trials, the accumulated data show that CR causes similar metabolic and physiologic adaptations [ 26 ], which as we will discuss later emulate only in part those detected in CR mice and rats.
Moreover, data on CR-mediated lifespan extension are apparently contradictory in the WNPRC and NIA study. They also found that CR protects monkeys against age-associated sarcopenia and grey matter volume shrinkage of several key subcortical regions [ 27 - 28 ].
Similarly, in Mattison et al. In the WNPRC study, CR significantly increased survival when considering only age-associated deaths i.
Nonetheless, it should be noted that in the NIA study 4 CR and 1 control monkeys have lived more than 40 years, which is a very long life for a Rhesus monkey [ 29 ].
The discrepancies in survival and disease incidence between the WNPRC and NIA studies raise several important questions that may help to further understand the mechanisms that regulate aging and mediate health and longevity. In the WNPRC study, the average difference in body weight between the CR and control monkeys was kg in the males, and 1.
In contrast, in the NIA study the difference in body weight between the CR and control monkeys was on average only 2. The problem is that in the WNPRC study the CR group calorie intake was individually calculated from the baseline consumption of every monkey, whereas in the NIA study the CR monkeys received an amount of food on the basis of a standard calculation i.
recommended caloric intake for age and body weight for the whole group to accommodate for the growing phase of the young monkeys [ 26 ]. However, as the monkeys got older the practice of group-wide reductions in the CR animal allotments when controls voluntarily reduced their intakes, has been discontinued, and food intake adjustments for the CR group have been based on animal health.
Interestingly, in both the NIA and WNPRC studies many of the metabolic and hormonal adaptations that are typical of the long-lived CR mice and rats did not occur in the CR monkeys. In the NIA study, unlike in CR rodents, serum concentrations of glucose, total cholesterol, LDL-cholesterol, C-reactive protein, testosterone and estrogen were not reduced, and serum cortisol were not increased in the CR monkeys [ 29 , 32 - 33 ].
Similarly, no difference in serum concentrations of total cholesterol, LDL-cholesterol, HDL-cholesterol, triiodothyronine, DHEA, IGF-1, or cortisol have been found between the CR and control monkeys in the WNPRC study [ 34 ].
No data have been published yet on the effects of CR on serum testosterone and estradiol concentration in the WNPRC study. How can we explain the difference in metabolic and hormonal adaptations in response to CR between CR rodents and monkeys?
Can this discrepancy be explained by species differences? In fact, we found that serum concentrations of glucose, total cholesterol, LDL-cholesterol, triiodothyronine, testosterone and estradiol were significantly lower in lean individuals practicing long-term moderate CR i.
CRONies than in age- and sex-matched controls [ 35 - 37 ]. It is our working hypothesis that in order to trigger a powerful anti-aging response, the body needs to perceive a CR-induced low energy availability that results in major simultaneous metabolic adaptations i.
low circulating levels of leptin, insulin, IGF-1, testosterone, estradiol, triiodothyronine and inflammatory cytokines coupled with increased serum concentrations of adiponectin, ghrelin and cortisol with energy resources shifted from growth and reproduction towards maintenance and repair activities.
Interestingly, leanness low adiposity induced by chronic exercise training i. high energy expenditure coupled with high energy intake also does not result in some of the same key metabolic adaptations that have been hypothesized to play a role in the CR-induced longevity, including a decrease in triiodothyronine, IGF-1 and core body temperature [ 36 , 38 , 42 ].
Consistently, data from experimental murine studies have shown that only CR slows aging and extends both average and maximal lifespan, whereas life-long exercise extends only average lifespan [ 43 ].

Consistently, data from experimental murine studies have shown that only CR slows aging and extends both average and maximal lifespan, whereas life-long exercise extends only average lifespan [ 43 ].
A remarkable difference between the NIA and WNPRC trials has been diet composition. The Wisconsin monkeys ate a pellet semi purified diet providing 3. In contrast, the NIA monkey diets are based on natural ingredients calculated on estimated requirements for nonhuman primates, with soy oil, fish, wheat, corn and alfalfa meal as fat source.
A mixture of fish, soybean, wheat, corn, and alfalfa meal provided the great majority of protein in the NIA study, and carbohydrates were primarily from ground wheat and corn [ 44 ].
Sucrose was only 3. The NIA diet macronutrient composition was In contrast, in the WNPRC study only the CR monkey diets were supplemented. Moreover, in contrast to the WNPRC semi-purified diets, the NIA natural ingredient-based diets contain a wide variety of phytochemicals, minerals, and omega-3 fatty acids, which are known to have independent positive health effects on several metabolic pathways [ 45 - 47 ].
For examples, certain plant foods contain a wide range of phytochemicals i. polyphenols, catechins, stilbenes, isothiocyanates, terpenes, sterols, indoles, and organosulfur compounds and vitamins that have shown beneficial effects against inflammation, oxidative stress, and on other molecular pathways that regulate blood pressure, atherosclerosis and carcinogenesis [ 48 ].
In summary, the WNPRC diet resembles more closely the typical modern Western diet rich in refined and processed foods; in contrast, the NIA diet is more similar to the traditional Mediterranean or Japanese diet, rich in fish and minimally processed plant-based foods.
Therefore, it is possible that the beneficial effects on lifespan of the combination of phytochemical-rich pescovegetarian diets and mild CR in the NIA control monkeys are already maximized. Consistently, average lifespan for both the NIA CR and control monkeys was markedly higher Accumulating data suggest that protein intake and dietary aminoacid composition play an important role in regulating mTOR activity, serum IGF-1 concentrations, and longevity [ 23849 - 54 ].
Our data show that in humans, unlike in rodents, severe CR does not reduce serum IGF-1 concentration unless protein intake is also reduced close to the USDA recommended intake i.
Data from genetic animal and human studies indicate that serum IGF-1 concentration is an important regulator of aging [ 255 - 56 ], and has been found to be inversely correlated with median lifespan in 31 genetically diverse inbred mouse strains [ 57 ]. The old dogma that only calorie intake, and not macronutrient composition and in particular protein intakeis an important regulator of lifespan is based on a flawed interpretation of a study published by the Masoro's group in The control group ate a usual protein content diet ad libitum [ 60 ].
Even under the best husbandry and dietary conditions i. e NIA CR monkey studyaverage and maximal lifespan of rhesus monkeys is ~31 and ~40 years, respectively. In contrast, average and maximal lifespan in humans is ~80 and ~ years, respectively.
The reason why Rhesus monkeys lifespan is much shorter than in humans is not known, and may involve a different rate of accumulation of unrepaired molecular and cellular damage with time.
Therefore, it is extremely important to study the health and longevity effects of CR without malnutrition in humans. Whether or not CR without malnutrition will extend lifespan in humans is not known yet, but accumulating data indicate that moderate CR with adequate nutrition has a powerful protective effect against the development of obesity, type 2 diabetes, inflammation, hypertension and cardiovascular disease, which are major causes of morbidity, disability and mortality [ 37 ].
Accordingly, Lloyd-Jones and colleagues found that in men and women from the Framingham Heart Study with normal cardiovascular risk profile at age 50 i. total glycemia 2 and no smoke the lifetime probability of developing an atherosclerotic cardiovascular disease was very low i.
In humans calorie restriction without malnutrition also results in a consistent reduction in circulating levels of growth factors, anabolic hormones, adipokines and inflammatory cytokines, which are associated with an increased risk of some of the most common types of cancer [ 63 ].
It is important to note that none of the 50 men and women age range yrs practicing long-term CR with adequate nutrition is taking any medication or has developed any chronic disease so far.
Moreover, CR in these individuals resulted in an amelioration of two well-accepted markers of cardiovascular aging, i. left ventricular diastolic function and heart rate variability [ 64 - 65 ]. These data indicate that CR exerts direct systemic effects that counter the expected age-associated changes in myocardial stiffness and autonomic function so that LV diastolic function and heart rate variability indexes in CR individuals are similar to those of individuals 20 years younger on a typical Western diet.
More studies are needed to understand how macro- and micro-nutrients, endurance exercise, and other environmental and psychological factors interact with CR in modulating metabolic and molecular pathways that regulate health and longevity.
Both excessive dietary restriction and overnutrition are different forms of malnutrition that lead to organ dysfunction and increased mortality. Even in rodents, excessive CR imposed on some strains of mice increases mortality. The problem is that the rate of physiologic development and sexual maturation varies among different strains of rodents, so that the lifespan response to CR may be different.
Forty percent CR may be optimal in some strains of mice, but can cause severe starvation and increased mortality in others, which would benefit from a lower degree of CR.
The same applies to humans, in which severe CR could be detrimental in some populations e. children, older adults, pregnant women, etc. Randomized, CR-controlled, long-term survival studies in humans will never be performed because of obvious problems with long-term compliance and costs of such a long study.
Nonetheless, we hope that by following the health status of individuals practicing long-term CR without malnutrition i. the CRONiesin particular of those who are now in their 70s and 80s, we could gain soon some information about the effects of CR on successful aging and healthy longevity in humans as well.
