Protein products

The problem of being overweight is an urgent problem for many, but it can only be solved by combining exercise and diet.If you are serious about taking care of your body, losing weight and building beautiful muscles, then you should try a protein diet.This is one of the most effective and you don't have to starve.On the contrary!The food will be very filling.

Remember that proteins are the main building blocks of our body.In addition, they perform many other tasks in order to support life, so their presence in a person's daily diet is mandatory.Proteins are made up of amino acids and are of plant and animal origin.The most valuable are animal proteins, which contain all the amino acids necessary for humans.Plant polypeptides are not as rich in amino acids, so their nutritional value is lower.In case of protein deficiency, muscle mass begins to decrease, it is gradually replaced by fat, immunity and resistance to stress decrease, fatigue appears more quickly, and the condition of the skin, hair and nails noticeably deteriorates.Normally, a person needs 1 gram of pure protein for every kilogram of body weight per day.

The essence of the 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 (only vegetable) are present in minimal amounts;
  • Protein-containing foods are supplemented with small amounts of vegetables and fruits for better digestion.

It is well known that carbohydrates are the main source of energy.When they are completely removed from the diet, there is a lack of energy, and then the body begins to burn glycogen and then fats.

  • Foods on the protein diet should be taken in small portions, every 2.5-3 hours, 5-6 times a day, while exercising daily.
  • Special attention must be paid to the quality of the products.Sausages, smoked meats and semi-finished products from the supermarket should definitely be excluded, because first-class meat and fats are not always used in their preparation.In addition, all kinds of vegetable and chemical additives - preservatives, dyes, aromas, etc.
  • Preference should be given to lean types of meat, poultry and fish, because the abundance of lipids interferes with the complete absorption of protein.In this regard, it is better to avoid the consumption of salmon, catfish, goose and duck, cod liver, pork and beef breast.

Contraindications and disadvantages of the protein diet

The 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 enough vitamins, microelements and other beneficial substances necessary for humans.In addition, a large amount of protein in the diet can lead to acidification of the blood, as evidenced by a pH falling below 7.35-7.45.In this case, the body needs more calcium, which begins to remove it from the bones.This threatens the development of osteoporosis.Therefore, we can use the protein diet for a maximum of one week, and then take a longer break.Nutritionists mostly say that such a diet can only be used every six months, and some experts follow a stricter approach: no more than once a year, because it puts a lot of strain on the organs of the digestive system.

The following side effects may occur with a protein diet:

  • Animal protein takes a long time to digest, and if you lack carbohydrates and fiber, this process takes even longer.As a result, food stays longer in the intestines, the processes of rotting and fermentation become more intense, which leads to bloating and bad breath.
  • The load on the kidneys increases, which can cause swelling in the legs and bags under the eyes, as well as in the liver.
  • Due to the slow digestion of food, constipation and exacerbation of gastritis and enterocolitis are possible.
  • There may be an increase in blood pressure, an increase in cholesterol and a risk of thrombosis.
  • You feel tired faster and people are more easily irritated.
  • In women, hormonal imbalance and ovarian dysfunction are possible.

It follows from the above that the 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 teenagers.

Sweets lovers will probably have a hard time tolerating this diet.Due to the lack of carbohydrates, they may experience increased fatigue and nervousness.Often, after completing the course, they consume high-calorie sweets again, quickly regaining the lost kilograms.But for carnivores, this will not be a burden.

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

Prohibited and permitted foods on a protein diet

The protein diet completely excludes the following foods:

  • sweets (cakes, cakes, candies and other desserts, including natural honey);
  • sweet fruits (bananas, persimmons, dates, figs, apricots, grapes, watermelon);
  • flour batches, 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 the desktop:

  • lean meat and poultry (veal, beef, rabbit, skinless chicken, turkey fillet);
  • lean fish, seafood, canned fish in oil;
  • offal (liver, tongue, lungs, kidney)
  • 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 berries;
  • tomatoes, cabbage, cucumbers, zucchini, greens;
  • sugar substitutes;
  • oatmeal, brown rice, buckwheat, bran;
  • vegetable oil (linseed, olive);
  • water – 1.5 liters per day, tea, coffee without sugar, fresh juices.

The weight of the portion consumed at once cannot exceed 250 grams, and the daily energy value of the food is 1200 kcal.The main focus is on meat, and fruits, vegetables and bran are auxiliary products.They contain fiber, which is necessary for normal digestion, since protein-containing foods cause constipation.Normally, humans also need carbohydrates;in addition to a protein diet, it is replaced with oatmeal or brown rice.The proportion of these products can be increased if fatigue is noticeably increased or dizziness occurs.You can also take additional multivitamins, as they are missing from your daily diet.

Protein in foods

  • In the case of a protein diet, it is recommended to prepare the simplest possible meals.
  • Meat, fish and poultry can be boiled, steamed, grilled or baked in the oven with a minimum amount of vegetable oil, and can also be steamed.
  • You should not get carried away with spicy spices and additives, and you should not add too much salt or pepper to food.For piquancy, we can add just a little mustard.
  • Store-bought sausage is not suitable for a protein diet.
  • Low-fat fermented milk products - cottage cheese, hard cheese - fit perfectly into the protein diet.
  • For dinner, you can eat protein shakes, which are sold in sports stores as sports nutrition, especially during heavy physical activity.

Sample protein diet daily menu

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 stick to the diet, the more vitamins and micronutrients it should contain.

An approximate power supply diagram might be:

  • 1. 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 fruit juice diluted with water.

Most often, the protein diet is kept for 5-7 days, less often - for 14 days.It is extremely rare that if the body easily tolerates such a diet, then it is followed for a month, but doctors strongly recommend not to experiment.The one-week protein diet menu usually contains a small amount of vegetables and fruits, but as its duration increases, their amount should increase.And if you feel very tired and sleepy, it is better to increase the amount of carbohydrates.Therefore, the 14-day protein diet menu usually includes more oatmeal, brown rice, buckwheat and vegetables.

Types of protein diet

There are many options for a protein diet.All of them 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 because the daily diet is fairly balanced.Avoiding fats and limiting carbohydrates is also expected, but fruits and vegetables are allowed in fairly large amounts.Eggs, chicken or quail are eaten boiled or baked in the oven 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, baked goods made from white wheat flour are completely excluded.You can also 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 the consumption of skinless chicken, turkey, fish, low-fat dairy products, a spoonful of oat bran a day, and then vegetables are included after a few days.

Protein diet during pregnancy and breastfeeding

During pregnancy and breastfeeding, proteins are especially needed, but the diet of a pregnant or lactating woman must be balanced in all respects.During this period, the woman is in great need of fats, carbohydrates, vitamins, minerals, trace elements and other valuable substances, and the protein diet in its pure form cannot provide all of this.Therefore, it is not recommended for pregnant and lactating women.

What to watch out for

Nutritionists and doctors categorically do not recommend switching to a protein diet without prior consultation with specialists, because this can aggravate chronic diseases.In addition to a two-week course, a multivitamin should be taken, and in case of increased fatigue and irritability, the menu should be enriched with carbohydrates.It is strictly forbidden to combine such nutrition with drugs and alcohol.

How to get off the diet

You should gradually exit any diet so that the lost kilograms do not return in a short time.First of all, you should not drastically increase the size of the portions.The previously excluded foods can be added little by little, but flour and sweets should be the last in the daily diet.It is better to increase the amount of fruits and vegetables and cereals.You should continue to eat lean meat, fish and dairy products.Alcohol consumption is allowed no earlier than 5 days after switching to a regular diet.

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