The problem of excess weight is an urgent problem for many, but this can only be solved by combining physical exercise with dietary nutrition.If you have seriously decided to take care of your body, lose weight and at the same time create beautiful muscle definition, you should try the protein diet.This is one of the most effective methods and you do not need to starve.Quite the opposite!The meal will be quite satisfying.

Let's not forget that proteins are the main structural elements of our body.They also perform many other functions to support life, so they are essential to be present in a person's daily diet.Proteins consist of amino acids and are of plant and animal origin.Animal proteins are considered the most valuable proteins that 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 lack of protein, muscle mass begins to decrease, it is gradually replaced by fat, immunity and resistance to stress decrease, fatigue sets in faster, and the condition of the skin, hair and nails noticeably worsens.Normally, a person needs 1 g of pure protein per day for every kilogram of weight.

The essence of the protein diet

The protein diet is based on the following assumptions:

  • simple carbohydrates are completely excluded;
  • Proteins make up 60% of the daily diet;
  • oils (vegetable only) are present in minimal quantities;
  • For better digestion, protein foods are supplemented with small amounts of vegetables and fruits.

It is known that carbohydrates are the main source of energy.When completely removed from the diet, an energy deficit occurs and the body then begins to burn glycogen and then fat.

  • Foods on a protein diet should be taken in small portions 5-6 times a day, every 2.5-3 hours when doing daily fitness.
  • Particular attention should be paid to the quality of the products.Sausages, smoked meats and semi-finished products from the supermarket should be strictly excluded, because not always premium meat and fats are used in their preparation.It also contains all kinds of herbal and chemical additives (preservatives, dyes, flavors, etc.).
  • Preference should be given to lean varieties of meat, poultry and fish, since the abundance of lipids prevents the full absorption of protein.In this regard, it is better to refrain from eating salmon, catfish, goose and duck, cod liver, pork and veal breast.

Contraindications and disadvantages of protein diet

Protein diet gives excellent results in a short time, but it cannot be recommended for everyone because it is not balanced.Due to the low content of vegetables and fruits, the body does not receive a sufficient amount of vitamins, microelements and other beneficial substances necessary for a person.Additionally, high amounts of protein in the diet can lead to acidification of the blood, as evidenced by a pH reading falling below 7.35-7.45.In this case, the body needs more calcium and this calcium begins to be removed from the bones.This threatens the development of osteoporosis.Therefore, the protein diet can be continued for a week at most, and then a long break can be taken.Nutritionists mostly say that such a diet can be followed only once every six months, and some experts adhere to a more stringent approach: no more than once a year, as it creates a large load on the organs of the digestive system.

The following side effects may occur on a protein diet:

  • Animal proteins take a long time to digest, and when carbohydrates and fiber are insufficient, this process takes even longer.As a result, food remains in the intestines longer, decay and fermentation processes become more intense, leading to bloating and bad breath.
  • The load on the kidneys increases, which can cause swelling in the legs, bags under the eyes and liver.
  • Due to slow digestion of food, constipation and exacerbation of gastritis and enterocolitis are possible.
  • There may be fluctuations in blood pressure, an increase in cholesterol levels is possible, and the risk of thrombosis increases.
  • They get tired more quickly and people get angry more easily.
  • In women, hormonal imbalance and ovarian dysfunction are possible.

From the above it follows that a protein diet is contraindicated in the following cases:

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

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

Sweet lovers will most likely have a hard time tolerating this diet.They may experience increased fatigue and irritability due to carbohydrate deficiency.Often, after completing the course, they start high-calorie sweets again and quickly regain the lost kilograms.But for meat eaters, this will not be a burden.

The main advantage of the diet is the constant feeling of fullness, because protein foods take longer to process.In addition, since protein foods help build muscle mass, this type of nutrition is very suitable for bodybuilders to dry their bodies.

Foods prohibited and allowed on a protein diet

The protein diet completely excludes the following foods:

  • desserts (cakes, pastries, candies and other sweets, including natural honey);
  • sweet fruits (bananas, persimmons, dates, figs, apricots, grapes, watermelon);
  • bakery dishes, pasta and bakery products;
  • fried and spicy foods, sauces, sausages, smoked meats, marinades;
  • potatoes, legumes, cereals;
  • animal fats;
  • sweet drinks, soda, alcohol, store-bought juices.

Instead, the following should appear on your table:

  • lean meat and poultry (veal, veal, rabbit, skinless chicken, turkey fillet);
  • lean fish, seafood, canned fish in oil;
  • offal dishes (liver, tongue, lungs, kidneys)
  • raw, boiled eggs, omelets;
  • low-fat milk and fermented milk products;
  • mushrooms;
  • low-fat cheese;
  • unsweetened pears, dried and fresh apples (preferably green), kiwi, citrus fruits, sour fruits;
  • tomatoes, cabbage, cucumber, zucchini, greens;
  • sugar substitutes;
  • oatmeal, brown rice, buckwheat, bran;
  • vegetable oil (linseed, olive);
  • water – 1.5 liters per day, tea, unsweetened coffee, fresh fruit juices.

The weight of the portion eaten at a time should not exceed 250 grams, and the daily energy value of the food should be 1200 kcal.The main emphasis is on meat, with fruits, vegetables and bran being auxiliary products.Since protein foods cause constipation, they contain fiber, which is necessary for normal digestion.Normally, a person also needs carbohydrates;With a protein diet, they are replaced by oatmeal or brown rice.The share of these products can be increased if fatigue increases noticeably or dizziness occurs.You can also take additional multivitamins to avoid deficiency in your daily diet.

Protein in foods

  • While on a protein diet, it is recommended to prepare the simplest meals possible.
  • Meat, fish and poultry can be boiled, stewed, grilled or baked in the oven with a minimum amount of vegetable oil, and also steamed.
  • You should not get carried away with spicy spices and additives and do not add too much salt or black pepper to your dishes.You can add a little mustard for spiciness.
  • Store-bought sausages are not suitable for a protein diet.
  • Low-fat fermented milk products - cottage cheese, hard cheeses - fit perfectly into a protein diet.
  • At dinner, you can drink protein shakes sold as sports nutrition in sports stores, especially during heavy physical activity.

Daily protein diet menu example

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

An approximate power supply scheme 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 yoghurt (low-fat cottage cheese, kefir, fermented baked milk, low-fat cheese);
  • Dinner: fish (beef, seafood, chicken) with vegetable salad, tea, fresh juice diluted with water.

Most often, the protein diet is kept for 5-7 days, less often - 14 days.It is extremely rare to follow for a month if the body easily tolerates this type of nutrition, but doctors strongly recommend not to experiment.A one-week protein diet menu usually includes small amounts of vegetables and fruits, but as the duration increases, their amounts should also increase.And if you feel very tired and sleepy, it is better to increase the amount of carbohydrates.That's why the 14-day protein diet menu usually includes more oatmeal, brown rice, buckwheat and vegetables.

Types of protein diets

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

  • One of the most popular options is the egg diet.It is relatively easy to tolerate as the daily diet is quite balanced.Fats are also expected to be avoided and carbohydrates limited, although fruits and vegetables are allowed in fairly large quantities.Eggs, chicken or quail are eaten boiled or baked as an omelette.
  • The basis of the Japanese diet is seafood, fish, rice and soy.Carbohydrates and fats are present but in limited amounts.Salt, sugar and 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 greens.
  • 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, switch to vegetables.

Protein diet during pregnancy and breastfeeding

Proteins are especially necessary during pregnancy and lactation, but the diet of a pregnant or lactating woman should be balanced in all respects.During this period, the woman really needs fats, carbohydrates, vitamins, minerals, trace elements and other valuable substances, and the protein diet in its pure form cannot provide all this.Therefore, pregnant and breastfeeding women are not recommended to adhere to it.

What to pay attention to

Nutritionists and doctors categorically do not recommend switching to a protein diet without prior consultation with specialists, as it can worsen chronic diseases.You should additionally take a multivitamin with a two-week course, and in case of increased fatigue and irritability, the menu should be enriched with carbohydrates.It is strictly forbidden to combine this type of nutrition with taking medications and alcohol.

How to get off the diet?

You should exit any diet gradually so that the lost weight does not come back after a short time.First of all, you should not increase portion sizes dramatically.Foods previously excluded can be added little by little, but flour and sweets should be the last thing in the daily diet.It is better to increase the amount of fruits and vegetables, as well as cereals.You should continue to eat lean meat, fish and dairy products.Alcohol is allowed no later than 5 days after switching to a regular diet.

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