Protein products

The problem of excess weight is an urgent problem for many, but it can only be solved by combining physical exercise and dietary nutrition.If you seriously decide to take care of your body, lose weight and create beautiful muscle definition at the same time, you need to try a protein diet.It is one of the most effective and you don't have to starve.Quite the opposite!The food will be quite filling.

Let's remember that proteins are the main building block of our body.In addition, they perform many other life-sustaining tasks, so their presence in a person's daily diet is mandatory.Proteins consist of amino acids and come from plant and animal origin.Animal proteins are considered the most valuable and contain all the amino acids necessary for humans.Plant polypeptides are not as rich in amino acids, so their nutritional value is lower.With a protein deficiency, muscle mass begins to decrease and is gradually replaced by fat, immunity and resistance to stress decrease, fatigue sets in more quickly, and the condition of skin, hair and nails noticeably deteriorates.Normally, a person needs 1 g of pure protein per kilogram of body weight per day.

The essence of a protein diet

The protein diet is based on the following postulates:

  • simple carbohydrates are completely excluded;
  • Proteins make up 60% of the daily diet;
  • Fats (exclusively vegetable) are present in minimal quantities;
  • Protein foods for better digestion are supplemented with a small amount of vegetables and fruits.

It is known that carbohydrates are the main sources of energy.If they are completely removed from the diet, an energy deficit is created and the body begins to burn glycogen and then fats.

  • Food on a protein diet should be consumed in small portions every 2.5-3 hours, 5-6 times a day, while simultaneously engaging in daily fitness.
  • Particular attention should be paid to the quality of the products.Sausages, smoked foods and semi-finished products from the supermarket should definitely be excluded, as first-class meat and fats are not always used in their preparation.In addition, it contains all kinds of herbal and chemical additives – preservatives, dyes, flavors, etc.
  • Preference should be given to lean meat, poultry and fish, as the richness of lipids interferes with complete protein absorption.In this regard, it is better to avoid eating salmon, catfish, goose and duck, cod liver, pork and beef brisket.

Contraindications and disadvantages of a protein diet

A protein diet gives excellent results in a short time, but cannot be recommended to everyone because it is not balanced.Due to the low content of vegetables and fruits, the body does not receive enough vitamins, microelements and other nutrients necessary for humans.In addition, high amounts of protein in the diet can lead to acidification of the blood, which is reflected in a pH value that drops below 7.35-7.45.In this case, the body needs more calcium, which is removed from the bones.This poses a risk of developing osteoporosis.Therefore, a protein diet can be followed for a maximum of a week and then take a longer break.For the most part, nutritionists say that such a diet can be used only once every six months, and some experts take a more strict approach: no more than once a year, since it places a heavy load on the organs of the digestive system.

The following side effects may occur with a protein diet:

  • Animal proteins take a long time to digest, and when carbohydrates and fiber are scarce, this process takes even longer.As a result, food stays in the intestines longer, the processes of putrefaction and fermentation become more intense, which leads to flatulence and bad breath.
  • The strain on the kidneys increases, which can lead to swelling of the legs and eye bags as well as the liver.
  • Due to the slow digestion of food, constipation and exacerbation of gastritis and enterocolitis are possible.
  • Increases in blood pressure may occur, an increase in cholesterol levels is possible and the risk of thrombosis increases.
  • You feel tired more quickly and become irritated more easily.
  • In women, hormonal imbalance and ovarian dysfunction are possible.

It follows that a protein diet is contraindicated under the following conditions:

  • kidney and liver diseases;
  • gout, diabetes, poor blood clotting;
  • chronic diseases of the gastrointestinal tract;
  • Pregnancy and breastfeeding.

It is also not suitable for older people, people with cardiovascular diseases and young people.

Lovers of sweets will most likely find this diet difficult to tolerate.Due to the lack of carbohydrates, increased tiredness and nervousness can occur.After completing the course, they often turn to high-calorie sweets again and quickly gain back the kilograms they lost.But it won't be a burden for meat eaters.

The main advantage of the diet is a constant feeling of satiety, since protein foods take longer to process.In addition, protein foods help build muscle mass, so this diet is very suitable for bodybuilders to dry their body.

Forbidden and permitted foods on a protein diet

A protein diet completely excludes the following foods:

  • sweets (cakes, pastries, candies and other desserts, including natural honey);
  • sweet fruits (banana, persimmon, dates, figs, apricots, grapes, watermelon);
  • flour dishes, pasta and baked goods;
  • fried and spicy foods, sauces, sausages, smoked meats, marinades;

The weight of one portion consumed should not exceed 250 grams, and the energy value of food per day should be 1200 kcal.The emphasis is on meat, fruits, vegetables and bran are auxiliary products.They contain fiber, which is necessary for normal digestion, since protein foods cause constipation.Normally humans also need carbohydrates;On a protein diet, they are replaced with oatmeal or brown rice.The proportion of these products can be increased if fatigue has noticeably increased or dizziness has occurred.You can also take additional multivitamins as these are missing from your daily diet.

Protein in food

  • When following a protein diet, it is advisable to prepare dishes that are as simple as possible.
  • Meat, fish and poultry can be boiled, stewed, baked on the grill or in the oven with a minimal amount of vegetable oil, and also stewed.
  • You should not get carried away with hot spices and additives or add too much salt or pepper to your dishes.For piquancy you can simply add a little mustard.
  • Store-bought sausages are not suitable for a protein diet.
  • Low-fat fermented milk products – cottage cheese, hard cheese – fit perfectly into a protein diet.
  • For dinner, you can drink protein shakes that are sold in sports stores as sports nutrition, especially during heavy physical activity.

Example of a protein diet menu for the day

The protein diet can be short-term (3-7 days) with three meals a day and long-term (usually 2 weeks) with split meals.The longer you follow the diet, the more vitamins and microelements it should contain.

An approximate power supply diagram might look like this:

  • 1st breakfast: yogurt without fillers (options: low-fat kefir, cottage cheese, two eggs), tea or coffee;
  • 2nd breakfast: green apple (orange, grapefruit, kiwi);
  • Lunch: chicken (fish, veal) with vegetables, brown rice, buckwheat, oatmeal (about five spoons);
  • Afternoon snack: natural yogurt (low-fat cottage cheese, kefir, fermented baked milk, low-fat cheese);
  • Dinner: fish (veal, seafood, chicken) with vegetable salad, tea, fresh juice diluted with water.

Most often, a protein diet is followed for 5-7 days, less often – 14 days.It is extremely rare that such a diet, if the body tolerates it well, is followed for a month.However, doctors strongly advise against experimenting.A protein diet menu for a week usually contains a small amount of vegetables and fruits, but as the duration increases, their quantity should increase.And if you feel very tired and sleepy, it is better to increase the amount of carbohydrates.Therefore, the protein diet menu for 14 days usually contains more oatmeal, brown rice, buckwheat and vegetables.

Types of protein diets

There are many options for a protein diet.They all belong to the low-carb group and are based on the same principle - more protein, fewer carbohydrates.

  • One of the most popular options is the egg diet.It is relatively well tolerated because the daily diet is quite balanced.Fats are also expected to be avoided and carbohydrates limited, but fruits and vegetables are allowed in relatively large quantities.Eggs, chicken or quail eggs, are eaten boiled or baked in the oven as an omelet.
  • The basis of the Japanese diet is seafood, fish, rice and soy.Carbohydrates and fats are present, but in limited quantities.Salt, sugar, baked goods made from white wheat flour are completely excluded.You are also allowed to eat cabbage, eggplant, zucchini, carrots, tomatoes, lean beef, chicken, eggs, unsweetened fruits, low-fat dairy products, and whole-grain bread.
  • Another type of protein diet is cottage cheese.In this case, the emphasis is on fermented milk products and vegetables.
  • The Dukan diet initially allows skinless chicken, turkey, fish, low-fat dairy products, a spoonful of oat bran per day, and after a few days vegetables are introduced.

Protein diet during pregnancy and breastfeeding

Proteins are especially necessary during pregnancy and breastfeeding, but a pregnant or breastfeeding woman's diet must be balanced in all respects.During this period, a woman absolutely needs fats, carbohydrates, vitamins, minerals, trace elements and other valuable substances, and a protein diet in pure form cannot provide everything.Therefore, compliance is not recommended for pregnant and breastfeeding women.

What you should pay attention to

Nutritionists and doctors categorically advise against switching to a protein diet without first consulting specialists, as this can aggravate chronic diseases.With a two-week treatment, you also need to take multivitamins; if you have increased fatigue and irritability, the menu should be enriched with carbohydrates.It is strictly forbidden to combine such a diet with taking medications and alcohol.

How do I get out of a diet?

You must end any diet gradually so that the kilograms you have lost do not come back after a short period of time.First, don't increase portion sizes too much.Foods that were previously excluded can be added gradually, but flour and sweets should be the last place in the daily diet.It is better to increase the amount of fruits and vegetables and grains.You need to continue eating lean meat, fish, and dairy products.Alcohol is allowed no earlier than 5 days after switching to a normal diet.

The main advantage of the protein diet is that it allows you to lose 3-5 kilograms in a few days without fasting, but it should be used very carefully and not for a long time.
