In the 1930s researchers discovered that laboratory rats fed a limited diet live about 40 % longer than normal and are resistant to many chronic illnesses typical of aging.

Researchers focused on two pathways that produce energy in muscles, glycolysis (sugar metabolism) and mitochondrial oxidative phosphorylation (OXPHOS) in both young and middle - aged rats that were fed a normal diet or a calorie - restricted diet.

To examine the relationships among VF, peripheral, and hepatic insulin sensitivity, we studied 4 - and 18 - mo - old male Sprague - Dawley rats (n = 42) fed ad libitum (4 AL and 18 AL) or moderately calorie restricted (18 CR) up to 18 mo of age.

The question is whether the same low - protein diets that prevent the growth of pre-cancerous lesions once they are formed also increase the toxicity of aflatoxin and other harmful chemicals, decrease the capacity for tissue repair, increase the risk of dying from chemical overdose, and promote the formation of pre-cancerous lesions when these diets are fed to the rats of the same strain, sex, age, and protein requirements.

This would also explain the case of weanling rats successfully blocking aflatoxin initiation fed 20 % protein, they were being fed an adequate amount of protein for their age, and hence were better at fighting off disease than their protein - starved counterparts.

Although it is difficult to extrapolate from rats to humans, we may try to use our results obtained at the tissue level in rats to interpret our previous observations obtained only at the whole - body level in elderly women (5,6,18), i.e., comparing the responses of liver and muscle protein synthesis to the pulse feeding pattern in the 2 age groups could suggest that there was also a positive effect of the pulse pattern at the muscle level in humans.

Because there was no significant effect of age, adult and old rat data were pooled and comparisons were made by using a two - way ANOVA to discriminate between the effects of protein feeding pattern (P), nutritional state (N) and their interaction (N × P).

However, protein feeding pattern was similar at both ages, i.e., adult rats consumed 25.3 ± 0.2 % of daily intake (4.46 ± 0.03 g of dry matter) and old rats consumed 25.1 ± 0.3 % of daily intake (4.22 ± 0.06 g) during the second meal (0800).

Then half of the rats at each age were switched to a 11/66/11 / 11 % repartition of daily proteins (pulse pattern) for 21 d. On d 21, epitrochlearis muscle degradation rates were measured in the postabsorptive (PA) or fed state (PP).
