Fischer 344 male rats were either fed ad libitum or 60% of the ad libitum intake. The restriction of food intake markedly increased the median length of life. Postabsorptive serum cholesterol and phospholipid concentrations increase in the ad libitum-fed rats with increasing age. Life-prolonging food restriction does not influence the ...
Yamada K - - 1980
The effect of food restriction on the intestinal weight and membrane digestive enzyme activities was observed in rats with diabetes induced by streptozotocin. The specific activities of disaccharidases of food non-restricted diabetic rats were not changed, but total activities were significantly increased due to the increase of intestinal mucosal weight. ...
Itoh S - - 1980
Earlier observations that food restriction for a short period of time in the morning produced an altered circadian rhythm of plasma corticosterone having the peak just before feeding time, and that the elevated plasma corticosterone levels declined promptly immediately after food presentation were confirmed. After a 14-day restricted feeding schedule, ...
Hastings M M - - 1979
Thyroxine (T4) and triiodothyronine (T3) concentrations in the plasma and their metabolic clearance and production rates were studied in pregnant protein-deficient and food-restricted rats on the 20th day of gestation.

Szepesi B - - 1977
The effect of repeated food restriction-refeeding was investigated in male Wistar rats. After the first food restriction, rats grew faster than did ad libitum-fed animals. The extent of compensatory growth was less with each subsequent restriction-release episode. Food intake determinations gave similar results: the extent of overeating decreased with each ...
Krieger D T - - 1977
Daytime restriction of food and water availability in nocturnal animals phase shifts the circadian periodicity of plasma corticosteroid concentrations and body temperature. These shifted rhythms persist in animals with lesions of the suprachiasmatic nuclei who are arrhythmic under normal conditions. These findings suggest the existence of an additional "clock" that ...
Hemm R D - - 1977
Following food restriction of pregnant CD-1 mice, the maternal serum corticosteroid levels and incidence of skeletal and visceral abnormalities of the progeny were determined. Dams from the groups receiving restricted food on gestation days 6 to 15 had increased resorptions, and the progeny had delayed ossification of the skeleton with ...
Takahashi K - - 1977
Influences of food restriction on the circadian adrenocortical rhythm were studied in blinded and unblinded rats under constant light (LL). Blinded rats, which were allowed to access to food ad libitum, manifested a phase shift of the circadian adrenocortical rhythm. However, restricted feeding between 19.00 and 21.00 h for 4 ...
