Hi folks:

I know this is twenty years old. But notable nonetheless:

" Effects of intermittent feeding upon growth and life span in rats.

Goodrick CL, Ingram DK, Reynolds MA, Freeman JR, Cider NL.

From weaning to death, 28 male Wistar rats were maintained on an ad

libitum (AL) diet, and 24 counterparts were provided the diet every-

other-day (EOD). The mean life span of the EOD group represented an

83% increase over that of the AL group. Furthermore, a Gompertzian

analysis of mortality rates suggested that the rate of aging was

retarded in the EOD group. While body weight and growth rate were

reduced in the EOD group, their growth duration was 75% longer

compared to the AL group. Significant positive relationships emerged

between life span and growth rate parameters in the AL group;

however, no significant relationships were found between life span

and body weight parameters in the EOD group. Therefore, in support of

the hypothesis that dietary restriction effects prolongevity through

retarded development, evidence was produced only in the between-group

comparisons of AL- and EOD-fed animals.

The abstract doesn't say how much less the fasting rats ate,

unfortunately.
