Caloric restriction leading to retardation of the aging process in
rats has a long history in academic science. The original reference dates
back to 1935:
C McCay, M Crowell, L Maynard (1935). "The effect of retarded growth upon
the length of life and upon ultimate size." Journal of Nutrition, vol 10,
At the time the discovery was not acclaimed because the 1930s were
obsessed with the new vitamins being discovered, whereas this paper was
sort of a less is more thing.
Many other researchers have validated the original claim that in
rodents low calorie diets cause extended mean life time, extended maximum
lifespan, and other indicators of aging (coat quality, disease resistance,
etc.). Currently the US expert is EJ Masoro, and an example might be:
EJ Masoro, I Shimokawa, and BP Yu "Retardation of the aging processes in
rats by food restriction" Annals NY Academy of Sciences (1991) v.621, p.
I am not certain as to the work on primates, but I vaguely remember seeing
an abstract by Richard Cutler reviewing primate caloric restriction.
