It has been suggested that adaptation to starvation may be impaired in @entity1 with @entity5 and that this may contribute to the development of @entity5 . We have investigated this by comparing the body composition, as well as the tissue composition of @entity353 , of a group of 49 @entity1 with @entity1820 and 91 @entity1 with @entity344 all of whom had sustained a @entity353 greater than 10% of their recalled pre-illness weight. Total body protein was calculated from total body @entity1568 measured by in vivo neutron activation analysis which also provided absolute values of @entity1372 , @entity3878 , @entity3151 , and @entity460 . The masses of muscle and nonmuscle protein were estimated using a validated compartmental analysis. Total body fat was derived using anthropometry. Total body water was estimated from the difference between body weight and the sum of body protein, fat, and minerals. The loss of body weight incurred by @entity1 with both benign and @entity5 was primarily muscle mass and body fat. Both groups of @entity1 retained nonmuscle protein. All @entity1 manifested, with increasing @entity353 , a progressive loss of muscle protein, fat, and water, which must represent the tissue composition of @entity353 . No significant differences between @entity1 with benign or @entity5 were demonstrated for any of the body composition parameters measured. The results of this study do not support the hypothesis that adaptation to starvation in @entity1 with @entity5 is in anyway different from that which occurs in @entity1 with benign disease.
