Abstract Caloric restriction in rodents is well known to retard the rate of aging, increase mean and maximum life-spans, and inhibit the occurrence of many age-associated diseases. However, little is known about the influence of short-term repeated fasting on longevity. In this study, female (NZB x NZW)F1 mice were used to test the physiological effect of short-term repeated fasting (4 consecutive days, every 2 weeks). The results showed that fasting mice survived significantly longer than the full-fed mice, in spite of the fasting group having a heavier body weight than the control group. Mean survival times for fasting and control mice were 64.0+/-15.3 and 47.9+/-9.4 weeks, respectively. Short-term repeated fasting manipulation was also effective on the prolongation of life-span in autoimmune-prone mice.
