Abstract:

Eight young adult men were used to investigate the metabolic effect of controlled 9-day periods of dietary conditioning on subsequent 5-day periods of caloric restriction 9stress periods. Half of the subjects were conditioned with diets high in fat about 68 per cent while the others had diets low in fat about 10 per cent. Each day of the stress periods a 148-gram portion of pemmican about 1000 calories wa ingested by each ubject. The criteria used to follow the metabolic response of the subjects were blood glucose levels, excretion rates of urinary ketone bodie , and nitrogen balances. The change in the average blood glucose level from the conditioning periods to the stress periods was not as drastic for the low fat conditioned men as for the men conditioned on diets high in fat. Neither the excretion rate of urinary ketone bodies n r the nitrogen balances were improved appreciably during the stre s periods by either type of dietary conditioning. Comparisons based on body size showed that the smallest men of the group had higher blood glucose level an l wer excretion rates of urinary ketone bodies in the econd stress period than did the larger men. The cata li m of tissue protein did not appear to be rel ted to body size. Author
