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 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.

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 polyunsaturated vegetable oils (corn, cottonseed oil, safflower oil, soybean or sunflower oils), olive oil, 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.

Have had diabetes since two yrs old am now forty nine doc says I have kidney damage and should get on a low protein diet thanks for your input.
Just bought the Kidney Diet Secrets and although it contains some good info I found it confusing that it touts a low protein diet (less than 25g) and yet their daily sample menu’s are 70g of protein.
Shouldn’t the daily sample menu’s provide menus for a diet of less than 25g of protein?
I wouldn’t buy this book if you are looking for help and sample menus for a low protein diet.
I started having some kidney problems 3 years ago and my crea abruptly dropped to very dangerous levels. I thought surgery or dialysis was the only way to go but the good thing is, I found nurse rachelle gordon’s “Kidney Diet Secrets”. I tried it started getting results after 3 weeks or so.
I highly recommend her guide ebook for anyone who has kidney disease as its very thorough and it comes with recipes and diet plans.
If you need more help, let me know. Ill be coming back to this site.
All the best,
