For a century, we have known that caloric restriction influences aging in many species. However, only recently it was firmly established that the effect is not entirely dependent on the calories provided. Instead, rodent and nonhuman primate models have shown that the rate of aging depends on other variables, including the macronutrient composition of the diet, the amount of time spent in the restricted state, age of onset, the gender and genetic background, and the particular feeding protocol for the control group. The field is further complicated when attempts are made to compare studies across different laboratories, which seemingly contradict each other. Here, we argue that some of the contradictory findings are most likely due to methodological differences. This review focuses on the four methodological differences identified in a recent comparative report from the National Institute on Aging and University of Wisconsin nonhuman primate studies, namely feeding regimen, diet composition, age of onset, and genetics. These factors, that may be influencing the effects of a calorie restriction intervention, are highlighted in the rodent model to draw parallels and elucidate findings reported in a higher species, nonhuman primates.
