Protein-free diet: features and approximate daily menu
One of the diets, which is rarely used in medicine, is protein-free.Its use is limited only to cases of severe damage to the kidneys, since it is physiologically inferior because of the too low content of proteins in it.Table of Contents: Principles of Protein-Free Diet Protein-Free Diet: Approved Products Sample menu for a protein-free diet.

Principles of Protein-free Diet
The protein-free diet is used in medicine for protein metabolism, as well as for suchSevere kidney pathologies like glomerulonephritis or kidney failure.
Note: protein diet is not used for weight loss, with its application, weight loss occurs solely by removing excess fluid from the body, but not the fat burning process.Athletes are strictly prohibited to combine workouts and protein-free diet is not recommended, as this can lead to the destruction of muscle tissue.
A protein-free diet is a conventional name.In fact, any normal life activity is impossible if the food completely lacks protein - the most important material for most of the metabolic processes.Therefore, in this type of diet, its content is simply reduced.
The rate of protein intake for an adult according to the World Health Organization is 0.75 g per kilogram of body weight.In the protein-free diet in case of its use in renal diseases, this figure is reduced to 0.55 g / kg.It is possible and even greater decrease in the proportion of proteins( up to 0.3 g / kg), but in this case a person must consume a daily mixture of amino and keto acids, from which the body will synthesize the proteins necessary for it.
Caloric content of any diet, including protein-free diet, must fully cover the energy costs of the body.There are many formulas by which you can calculate how many calories should contain the patient's menu.For more information on calorie counting, see How to calculate the ideal weight and daily requirement for calories.For simplicity, we can assume that this figure should be equal to 2200-2500 kcal.
A protein-free diet should be limited in terms of water and salt content.This is due to the need to prevent the development of edema - a frequent companion of kidney diseases.In this case, you should carefully consider the content of potassium in food.Most often, patients take significant doses of diuretics, washing this element out of the body, so its possible shortage should be compensated by the right selection of foods or medicines.
Protein-free diet: permitted products
There is an erroneous opinion that only protein products are included in the protein-free diet.However, nutritionists insist that there must be animal proteins in the diet, since they are the most complete.However, it is possible and nutrition is exclusively plant food, but in this case a person should also use mixtures of essential( vital) amino acids, which in vegetarian food is not enough.
Restrictions on protein-free diet are very few and concern products with the highest protein content.But even in this case, complete exclusion of protein-containing products is impossible. Here is what is allowed for use in the protein-free diet:
- protein-free or white wheat, made with the addition of bran bread;
- based on sago;
- Meat and fish:
- low-fat varieties in boiled, baked, roasted form( all in extremely limited quantities);
- Eggs - no more than one piece per day: they are consumed as a protein omelet or in the composition of dishes.
- Dairy products restrict.Are allowed:
- whole milk;
- cottage cheese is low-fat.
- Vegetables( raw and boiled):
- fruits and berries in any form( especially watermelon or melon);
- sugar, honey, jams, preserves;
- Cereals and pasta are sharply limited, instead of recommended special pasta.
- Any vegetable fats.
- Soft drinks are allowed from drinks( milk is allowed to be added), broths of wild rose and black currant( dilute in half with water), juices.
Absolutely all dishes should be prepared without salt.Vegetables should be soaked in water for a long time before use.Cooking dishes should be done in large quantities of water.
Sample menu for the protein-free diet
From all this variety of products, you can prepare a lot of amazingly delicious things.Yes, at first the taste will be somewhat unusual, but over time, people get used to everything and begin to find pleasure even in those things that previously seemed meaningless.
So, the daily diet of a patient with renal pathology can look like this:
- 25 g of viscous oatmeal;
- 30 white bread;
- 20 g of apple jam or jam;
- tea with sugar.
- salad of peeled cucumbers without dressing - 140 g;
- cabbage soup on a thin meat broth - 250 g;
- boiled pasta - 250 g;
- braised beef - 140 g;
- rye bread - 30 g;
- patty with cabbage filling( baked) - 75 g;
- apple refined - 100 g.
- cabbage salad with vegetable oil - 150 g;
- boiled rice - 250 g;
- cutlets from fish - 150 g;
- white bread - 30 g;
- Before going to bed:
- cookies - 50 g;
- kefir - half a cup.
This menu perfectly matches the needs of the body, has a balanced composition of nutrients and micro and macro elements.Its caloric content is 2500 kcal.
Non-protein diet: menu for the week for losing weight
Despite the fact that the protein-free diet is considered one of the curative, under certain conditions it can still be used for weight loss.On the Internet, you can find a lot of options for such rations, designed to get rid of 5-10 kilograms per week or 10 days.M The protein-free diet menu for a week looks quite simple:
- 1-2 day - only raw vegetables;
- Day 3 - vegetables, pears, apples;
- Day 4 - again vegetable, but boiled vegetables are allowed;
- 5-6 day - the same as the previous, but allowed sour cream or yogurt;
- Day 7 - vegetables with greens.
The effectiveness of this diet is questionable, as it is not balanced for any of the nutrients.Its caloric content is extremely low, which contradicts modern ideas about the fight against excess weight.However, it is really possible to lose weight for these 7 days, although not for the claimed 10 kilograms, but there will not be much benefit in this, since the main thing in the fight against excess weight is correction of improper dietary weight loss.And this protein-free diet can not provide.
Restrict the protein content of food only if its degradation products can harm the body.This is what happens with kidney failure and other kidney diseases.In all other cases, more physiological diets should be chosen.
