Low-Protein Diets

A low-protein diet is any diet in which the protein intake is reduced. Anyone diagnosed with kidney or liver disease may be prescribed a low-protein diet.

In any case, a diet which is especially low in protein should only be undertaken under medical direction.

Why is a low protein diet necessary?

Protein is needed, but can cause problems for diseased organs


Protein is necessary for a healthy body. When protein is metabolized by the liver and digested, urea is produced as a waste product. If the liver is diseased, then food metabolism is compromised.

If the kidneys, which are responsible for excretion of urea, are not functioning properly (renal failure), or if high levels of protein are continually present in the diet, urea builds up in the bloodstream causing loss of appetite and fatigue. A low-protein diet will reduce the workload on these organs.

It is usually the case that serious liver and kidney disease are accompanied by the need to limit salt or sodium intake due to high blood pressure or fluid retention. Table salt (the primary source of sodium in the diet) should therefore be limited, along with other foods with a high sodium content, as an additional feature of the low-protein diet.

Too much protein can worsen your health

It is generally accepted that a healthy person needs 40-60 grams of protein each day to remain in good health. However, it has been reported that the amount of protein typically consumed by people in affluent societies (American diet typically comprises 12-15% protein) may overtax the kidneys – to the extent that up to 30% of kidney function may be lost by the time someone is in their eighties.

High-protein diets for weight loss often recommend 30% or more protein in the daily diet, and in prolonged use can cause serious metabolic changes leading to bone loss and kidney stones!

Reduced protein intake can improve your health

Low protein diets (4-8% protein) are used routinely to treat patients with liver disease, kidney (renal) failure, and disorders involving the urea cycle, the metabolism, and amino acids.

How is a low-protein diet achieved?

Reduce the amount of protein

Some of each type of protein should still be consumed each day from the two main sources:

  • Animal products (fish, poultry, eggs, meat, dairy products) – considered high quality or complete protein.
  • Vegetable products (breads, cereals, rice, pasta, dried beans) – considered low quality or incomplete protein.

To reduce the amount of protein consumed, protein foods in recipes can be ‘stretched’ (to consume less) or reduced as against more of the low- or non-protein foods (less in proportion), making a smaller amount seem just as satisfying.

  • Use thinly sliced meats.
  • Fill with salad items like lettuce, alfalfa sprouts, cucumber, chopped celery, apple, parsley or water chestnuts.
  • Use lower protein foods (milk substitutes for cream soups, or rice or pasta) to make soups as filling but with less protein.
Main Dishes
  • Make the main dish of vegetables and grains, and treat meat as the side dish to your meal.
  • Use small pieces of meat and more vegetables in kebabs.
  • Make fried rice with vegetables and use less meat or shrimp.
  • For salads use crisp, fresh vegetables and only a few small strips of meat and egg.
  • For casseroles, reduce the amount of meat and increase the starch, pasta or rice. In recipes using soup, use a low sodium mix.
  • Use low-protein pastas and breads in the diet.
  • For cheeses, use smaller amounts of stronger-tasting cheeses (sharp cheddar, parmesan or romano) for plenty of flavor.

Boost calories to compensate

Decreasing protein in the diet may also mean a reduction in calories. To compensate so as to maintain a healthy weight, increase calories by substituting or adding certain ingredients with minimal protein content, such as:

  • Increase heart-healthy fats like monounsaturated vegetable oils (olive, avocado) and mayonnaise-type salad dressings.
  • Use candy and sweeteners (hard candy, gum drops, jelly beans, marshmallows, honey, jam and jelly – even sugar (diabetics need medical advice).
  • Use canned fruits in heavy syrup.

Sample low protein menu

  • Cheerios cereal or equivalent ¾ cup (3g)
  • non-dairy creamer ½ cup (0g)
  • ½ medium banana (.6)
  • orange juice ½ cup (.8g)
  • 1 cherry fruit roll up (0g)
  • 2 slices white bread (1.6g)
  • turkey breast 1 oz/28 g (4.8g)
  • lettuce (0g)
  • tomato ½ cup (.8g)
  • green beans ½ cup (1.2g)
  • mayonnaise 3 tsp (0g)
  • 1 medium apple (.3g)
  • fruit punch 4 fl oz/118 ml (0g)
  • 1 popsicle (0g)
  • lean hamburger 2 oz/56 g (10.5g)
  • white rice ½ cup (2.2g)
  • broccoli ¼ cup (.9g)
  • cauliflower ¼ cup (.6g)
  • tossed salad (1.5 cups) with 2 Tbsp ranch dressing (3g)
  • pineapple ½ cup (.2g)
  • gum drops 1 oz/28 g (0g)

Sample low protein menu contains

  • Protein: 30.5 grams
  • Calories: 1442
  • Fat: 48 grams
  • Carbohydrates: 237 grams
  • Sodium: 1270 mg

  7. Steve Wimer

    I’m on a low-protein, low-sodium diet. It works, but it’s hell: eat vegetables and fruits, supplement with 10 grams of amino acids (I use Amino bites). Find low protein “fun” food at cambrookefoods.com. Read Dr. Walzer’s book on kidney failure for more information.

  8. RM

    People why don’t you do a search online for low protein diet suggestions… or ask your doctor. Nobody on this board is going to send you a personalized diet sheet!

  16. Jyothy Nair

    My father has liver cirrohsis and is also a diabetic. Can you please advice a low protein diet

  17. humberto

    One of the problems I have is sticking to this low-protein diet. My nutritionist said I have to be on 5 oz. meats max per day I normally eat this in one sitting, but maybe I am not seeing the truth of the disease as I know something is bothering me. I could never follow directions without being watched. When I am watched and must report to some- one I will tend to follow more closely than when I am not watched at all.

  18. Ram

    Can you please suggest or advise a dietary guidlines for Type 2 DM, HTN, Nephrotic syndrome and hypercholesteremia and vegetarian.

    My mother is very ill and is to avoid high protein foods. Could you please send me a list of foods that are low in protein. My father is caring for her and is at a loss at what foods to prepare for her. A list broken down for him would be very helpful. Thank you

  22. RM

    Wow, this diet is terrible, filled with starches and sugars and processed crap foods. I was on a similar diet for the past year and gained 30 pounds.

    There are ways to eat less protein and lose weight – just eat a lot of veggies, fruits and beans.

  23. Matt Watson


    My wife’s renal count was a 9 leading to an extended hospital stay saving her life. She never had kidney failure in the past however she may have internal bleeding from several intestinal surgeries ten years ago.

    The doctor has suggested that this may cause her kidneys from being able to regulate her potassium. The catch 22 is that she needs to loss weight before anymore surgery can be done.

    So, I need to find a low potassium diet that allows her to healthly loss weight for her surgery without aggravating the little bowel she has left.

    Can anyone please point me to a good website, program or diet book that I can use to create the proper meals for her recovery?

  24. Emma Fessler

    Curious as to why the snacks are so sugar oriented even though I understand need for the calories…why not more fruit?

  25. Steve Wimer

    Low protein diet? Eliminate meat, fish, beans, eggs, cheese, and nuts. Supplement with amino acids. I follow this diet, with low sodium, as well. I subsist on vegetables and fruits, pretty much, with a little bread or pasta for variety. I use JoMar Labs 21 blend amino acids. It’s a tough diet to follow, but even worse if you don’t.

  26. jayne sandbothe

    I want to try the low protein diet, as I have end stage renal disese . I have 25% at this time.Am receiviing procrit shots.

    My hubby had liver cirrohsis,his feet (near the ankle) is swollen (water retension)he feel his feet is heavy, once in a while he will take water tablet(fruetmide)but feel very tired. Please advise is it due to low protein. what are the
    protein that can help him solve this problem.


    My son Varun ( 2 year and 9 months) as been diagonised with Hyperammonemia-Hyperornithinemia-Homocitrullinemia (HHH) Syndrome.

    Following are the values which are having above the normal value.

    a) Leucine 394umol/L ( should < 385)
    b) ornithine 443umol/L ( should < 278)
    c) C5 OH 0.74umol/L ( Should < 0.68)
    d) orn / citru 7.9 ( should < 1.5)

    Plasma ammonia 54.8 mcg/dl ( 27.00 -102.00)

    In the report they mentioned that this is aminoacid disorder.

    Also suggested that treatment may include protein ristricted diet and supplimentation with ornithine.

    Protein ristriction to less than 1.2g/kg per day prevents postprandial hyper amonimia and results in decreased concentraion of ornithine in blood .

    After the birth, after two weeks , he started losing weight ( from 2.7 birth weight to 2.1 kg). And he was admitted in NICU to give liver infect treatment and hyper amonia. We have given sodium benzoate up to 1 year and came under control and stoped. Every six months we are testing blood samples and amonia is in control.

    His activities are normal and but he is not gaining weight. Now he is weighing around 9.6kg (2 year and 9 months). For that reason they asked us to conduct above mentioned tests.

    They asked us to contact dietitian and she told us to give lesser milk products , nuts, grams and higher protein products and normal food.

    Could you please suggest us how to control Hyperornithinemia with the food. Also suggest us which are the supplements that can be given to him to increase weight .

    Do we need to take care any other precautions.And does it have any long term effect on him.
