high-protein diet

Also found in: Dictionary, Thesaurus, Legal, Encyclopedia, Wikipedia.

high-protein diet

a diet that contains large amounts of protein, consisting largely of meats, fish, milk, legumes, and nuts. It may be indicated in protein depletion that results from any cause, as a preoperative preparation, or for patients with severe burns and sepsis. It may be contraindicated in liver failure or when kidney function is so impaired that added protein could result in azotemia and acidosis.

high-protein· di·et

(hī-prō'tēn dī'ĕt)
A controversial regimen that provides large amounts of protein, either to resolve states of depletion or to allow intake of levels of protein greater than normal for athletic reasons. Reports suggest possible kidney disease as a result of this diet.

high-protein diet

one which provides more than 15% of energy as protein. Traditionally, high-protein diets are low-carbohydrate diets. These diets are claimed to be effective for the reduction of body mass and body fat. Extremely high-protein diets are claimed to suppress appetite through reliance on fat mobilization and ketone body formation. In addition, the elevated thermic effect of dietary protein, with a relatively low coefficient of digestibility (particularly in the case of plant proteins), reduces the net calories available from ingested protein compared with a well-balanced diet of equivalent caloric value. The long-term success of high-protein diets remains questionable and they may even pose health risks, including kidney damage, increased blood lipoprotein levels and dehydration. See also low-carbohydrate ketogenic diets.


the customary amount and kind of food and drink taken by an animal from day to day; more narrowly, a diet planned to meet specific requirements of the animal, including or excluding certain foods. See also winter diet.

acid diet
diets of low alkalinity which are fed to cows to prevent milk fever. The diet in the 4 weeks preceding parturition, which is ordinarily highly alkaline, is supplemented with calcium chloride, and aluminum and magnesium sulfates, to reduce this alkalinity.
bland diet
one that is free from any irritating or stimulating foods.
calcium homeostatic diet
a diet aimed at maintaining normal blood levels of calcium in recently calved cows.
calculolytic diet
formulated to aid in the dissolution of struvite uroliths. Usually provides a low intake of protein, restricts phosphorus and magnesium, and acidifies the urine. Additional salt may also be included. These have been used successfully in dogs and cats.
deficient diet
see nutritional deficiency disease.
drought feeding diet
elemental diet
contains nutrients as small molecular weight compounds, i.e. proteins as amino acids or peptides, carbohydrates as oligosaccharides or monosaccharides, and fats as medium-chain triglycerides. Used in the treatment of gastrointestinal disease. Called also monomeric diet.
elimination diet
one for diagnosing food allergy, based on the sequential omission of foods which might cause the clinical signs in the patient.
geriatric diet
may vary in composition; generally, they are formulated to provide lower energy intake and increased digestibility.
gluten-free diet
one without wheat, rye, barley, buckwheat, or oats or related products.
high-calorie diet, high-energy diet
one that furnishes more calories than needed for maintenance; used to increase body condition, in recovery from illness and for maintenance under stressful conditions.
high-fiber diet
one relatively high in dietary fiber; in dogs and cats, used in the management of large and small bowel diarrhea, diabetes mellitus, constipation and obesity.
high-protein diet
one containing large amounts of protein; used in the management of dogs and cats recovering from illness.
home-prepared diet
one prepared in the home kitchen, in contrast with commercially prepared pet foods.
hypoallergenic diet
one formulated to avoid suspected allergens; usually used in the management of allergic skin or bowel disease.
liquid diet
a diet limited to liquids or to foods that can be changed to a liquid state.
low-calorie diet
one containing fewer calories than needed to maintain weight; normally used in management of obesity in dogs and cats.
low-fat diet
one containing limited amounts of fat; used in the management of pancreatic disease, bowel disease, and obesity in dogs and cats.
low-fiber diet
see low-residue diet (below).
low purine diet
in dogs and cats, generally a low-meat diet.
low-residue diet
one with a minimum of cellulose and fiber and restriction of connective tissue found in certain cuts of meat. It is prescribed for irritations of the intestinal tract, after surgery of the large intestine, in partial intestinal obstruction, or when limited bowel movements are desirable. Called also low-fiber diet.
low vitamin A diet
one containing low levels of vitamin A; in dog and cat diets, this would mean little or no organ meats. The only probable indication for such a diet is in the treatment of hypervitaminosis A.
lower urinary tract disease diet
one that promotes acidification of the urine and containing restricted magnesium and phosphorus, and sometimes increased salt.
monomeric diet
see elemental diet (above).
phosphate-restricted diet
one containing restricted amounts of phosphorus; used in the management of chronic renal disease.
polymeric diet
meal replacement diets; fed to animals with almost normal gastrointestinal function. Proteins, fats and carbohydrates are present in high molecular weight forms.
sodium-restricted diet
used in management of congestive heart failure and systemic hypertension in dogs and cats.
