“…Protein intake is reduced to lighten the excretory load of the kidneys, while the caloric value of the diet is raised to counter-balance the protein reduction and to ensure that body proteins will not have to be catabolised for energy (Giovannetti and Maggiore 1964;Richards and Hoe 1967;Edney 1970). The basal protein deficient diet used in man by Giovannetti and Maggiore (1964) contained 0.5 g of proteidkg body weight/day, with the bulk of the calories being supplied in animal and vegetable oils, starches, sugar and honey, In a long-term study of renal disease in dogs, Richards and Hoe (1967) fed a good quality meat and rice diet containing 0.75 g protein/kg body weight, with minor variations in some cases.…”
