The problem of excess weight is a serious problem for many people, but it can be solved only by combining physical exercise with dietary nutrition.If you decide to seriously take care of your body, lose weight and create beautiful muscle definition, you need to try a protein diet.This is one of the most effective, and you won't have to starve.quite the contrary!The food will be quite filling.

Let's remember that protein is the main building block of our body.In addition, they also perform many other functions to support life, so their presence in a person's daily diet is essential.Proteins are made of amino acids and come in plant and animal origin.Animal proteins are considered the most valuable, containing all the amino acids necessary for humans.Plant polypeptides are not rich in amino acids, so they have low nutritional value.With protein deficiency, muscle mass begins to decrease, gradually replaced by fat, immunity and resistance to stress decrease, fatigue rapidly begins, and the condition of the skin, hair and nails deteriorates significantly.Generally, a person needs 1 gram of pure protein per kilogram of weight per day.

essence of protein diet

The protein diet is based on the following principles:

  • Simple carbohydrates are completely excluded;
  • Proteins make up 60% of the daily diet;
  • Fats (especially vegetable) are present in minimal quantities;
  • Protein foods are complemented with small amounts of vegetables and fruits for better digestion.

It is 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 fat.

  • When doing daily fitness, food on a protein diet should be taken in small portions every 2.5-3 hours, 5-6 times a day.
  • Special attention should be paid to the quality of products.Sausages, smoked meats and semi-finished products from supermarkets should definitely be excluded, since first-class meat and fat are not always used in their preparation.In addition, it contains all kinds of herbal and chemical additives – preservatives, colors, flavors, etc.
  • Preference should be given to lean varieties of meat, poultry and fish, as the abundance of lipids hinders the complete absorption of proteins.In this regard, it is better to avoid eating salmon, catfish, goose and duck, cod liver, pork and beef brisket.

Contraindications and harms 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 enough vitamins, microelements and other beneficial substances necessary for a person.Additionally, high amounts of protein in the diet can cause acidification of the blood, as evidenced by pH readings that drop below 7.35-7.45.In such a situation, the body requires more calcium, which starts coming out of the bones.This increases the risk of developing osteoporosis.Therefore, the protein diet can be used for a maximum of a week, and then a longer break can be taken.Nutritionists for the most part say that such a diet can be applied only once every six months, and some experts adhere to a more strict approach: no more than once a year, as it creates a large load on the organs of the digestive system.

Protein diets may cause the following side effects:

  • Animal proteins take a long time to digest, and when carbohydrates and fiber are in short supply, this process becomes even longer.As a result, food remains in the intestines longer, the processes of putrefaction and fermentation become more intense, leading to flatulence and bad breath.
  • The load on the kidneys increases, which can lead to bags on the legs and under the eyes, as well as swelling on the liver.
  • Due to slow digestion of food, constipation and exacerbation of gastritis and enterocolitis are possible.
  • Blood pressure may increase, cholesterol levels may increase, and the risk of thrombosis increases.
  • People start feeling tired quickly and become irritable easily.
  • Hormonal imbalance and ovarian dysfunction are possible in women.

From the above it follows that protein diet is prohibited in the following situations:

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

It is also not suitable for older people, people with heart diseases and teenagers.

Sweet lovers will probably find this diet difficult to tolerate.Due to lack of carbohydrates they may experience fatigue and nervousness.Often, after completing the course, they again take high-calorie sweets, thereby quickly gaining back the lost kilograms.But this will not be a burden for meat eaters.

The main advantage of the diet is a constant feeling of satiety, since protein foods take longer to be processed.In addition, protein foods help build muscles, so this type of nutrition is very suitable for drying bodies of bodybuilders.

  • While on a protein diet, it is advisable to prepare the simplest dishes possible.
  • Meat, fish and poultry can be boiled, baked, cooked on the grill or in the oven with a minimum amount of vegetable oil, and also steamed.

Sample protein diet menu for the day

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

An approximate power supply diagram might be as follows:

  • First breakfast: yogurt without fillers (options: low-fat kefir, cottage cheese, two eggs), tea or coffee;
  • Second breakfast: green apple (orange, grapefruit, kiwi);
  • Lunch: chicken (fish, veal) with vegetables, brown rice, buckwheat, oatmeal (about five tablespoons);

  • Dinner: fish (veal, seafood, chicken) with vegetable salad, tea, fresh 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 nutrition, it is followed for a month, but doctors strongly recommend not to experiment.The protein diet menu for a week usually consists of a small amount of vegetables and fruits, but as its duration increases, their quantity should also increase.And if you feel very tired and drowsy then it is better to increase the amount of carbohydrates.Therefore, the protein diet menu for 14 days usually includes more oatmeal, brown rice, buckwheat and vegetables.

types of protein diets

There are many options for protein diet.All of them belong to the low carbohydrate 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 quite balanced.It is also expected to avoid fats and limit carbohydrates, but fruits and vegetables are allowed in fairly large quantities.Eggs, chicken or quail are eaten boiled or cooked in the oven as omelettes.
  • 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.

  • The Dukan diet initially allows skinless chicken, turkey, fish, low-fat dairy products, one teaspoon of oat bran per day, and vegetables are introduced after a few days.

Protein diet during pregnancy and breastfeeding

Proteins are especially essential during pregnancy and breastfeeding, but the diet of a pregnant or breastfeeding woman should be balanced in all respects.During this period, a 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 lactating women are not recommended to follow it.

what to pay attention to

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

how to get off diet

You need to get out of any diet gradually so that the lost kilograms do not return 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 grains along with fruits and vegetables.You need to continue to eat lean meat, fish and dairy products.Alcohol is not allowed before day 5 of switching to a regular diet.
