a diet proportionally low in protein, usually designed for persons who must restrict protein intake because of a metabolic abnormality associated with kidney failure or liver disease.
A diet that provides less than 1.5 g/kg/day of protein during growth periods or less in adults. Adults with renal failure should receive no less than 0.6 g/kg/day of protein to avoid a negative nitrogen balance; low-protein diets are indicated for patients with renal failure, as reduced protein reduces anorexia, nausea, vomiting and if begun early, may slow the progression of disease.
