Protein for weight loss: which is better

Protein for weight loss: which is better

Section 1: Fundamentals of protein and weight loss

1. What is protein? Protein, or protein, is one of the three main macronutrients, along with carbohydrates and fats. It consists of amino acids, which are building blocks for tissues of the body, including muscles, bones, skin, hair and organs. Protein plays a key role in many processes, such as restoration and growth of tissues, the production of enzymes and hormones, maintaining the immune system and transporting nutrients.

2. The role of protein in weight loss. Protein plays an important role in the process of losing weight thanks to several mechanisms:

   • Saturation: Protein has a high ability to cause a feeling of satiety. It slows down the emptying of the stomach and stimulates the production of hormones that suppress the appetite, such as the Peptide Yy (PYY) and the glocagon-like peptide-1 (GLP-1). This helps to reduce calorie intake and prevent overeating.
   • Thermal effect of food (Tef): The body spends more energy on digestion of protein compared to carbohydrates and fats. This means that about 20-30% of calories obtained from protein are burned in the process of digestion, which helps to increase energy consumption.
   • Saving muscle mass: During losing weight, the body may begin to destroy muscle tissue for energy. The use of a sufficient amount of protein helps to maintain muscle mass, which is important to maintain metabolism and prevent a slowdown in metabolism. The muscles actively burn calories, so the preservation of muscle mass contributes to more effective weight loss.
   • Increase in metabolism: An increase in protein consumption can slightly increase metabolism at rest (RMR), which means that the body burns more calories even at rest.

3. How much protein is needed for weight loss? The recommended daily protein consumption (RDA) is 0.8 grams per kilogram of body weight for adults. However, for weight loss, it is often recommended to increase protein consumption to 1.2-1.6 grams per kilogram of body weight. This can help increase the feeling of satiety, maintain muscle mass and accelerate metabolism. It is important to note that the individual needs for protein can vary depending on the level of physical activity, age, health and goals for weight loss.

4. Protein in food. Protein is found in various foods of animal and plant origin.

   • Animal sources: Meat (chicken, turkey, beef, pork), fish (salmon, tuna, cod), eggs, dairy products (milk, yogurt, cheese).
   • Plant sources: Legumes (beans, lentils, peas, chickpeas), tofu, pace, movie, nuts, seeds.

5. Protein supplements. Protein additives are a convenient way to increase protein intake, especially when it is difficult to get a sufficient amount of protein from food. They are available in various forms, such as powders, bars and drinks. Protein powders can be added to smoothies, cocktails, oatmeal or pastries.

Section 2: Types of protein additives

1. Serum protein. Serum protein is one of the most popular types of protein additives. It is produced from serum, a by -product of cheese production. Whey -propelled protein is quickly absorbed by the body and contains all nine essential amino acids, which makes it a full -fledged source of protein. It is available in several forms:

   • Wastein serum concentrate (WPC): Contains from 70% to 80% protein. The rest is lactose, fats and carbohydrates. WPC is the most economical version of serum protein.
   • Wastein protein isolate (WPI): Contains more than 90% of protein. It is subjected to additional processing to remove most lactose and fats, which makes it suitable for people with lactose intolerance.
   • Hydrolysis of serum protein (WPH): It is hydrolysis, the process of splitting protein into smaller peptides. This facilitates and accelerates its assimilation. WPH is often used in sports nutrition.

2. Casein protein. Casein protein is also made of milk. It is absorbed more slowly than whey protein, which makes it a good option for consumption before bedtime. Slow assimilation of casein provides a constant flow of amino acids during the night, which helps to prevent the destruction of muscle tissue.

3. Soy protein. Soy protein is a plant source of protein obtained from soybeans. It contains all nine essential amino acids and is a good alternative to vegetarians and vegan. Soy protein also contains isoflavons that have antioxidant properties.

4. Egg protein. Egg protein is made of egg protein. It contains all nine essential amino acids and does not contain lactose. Egg protein is a good option for people with allergies to dairy products.

5. Rice protein. Rice protein is a plant source of protein obtained from brown rice. It is hypoallergenic and easily absorbed. However, rice protein does not contain all nine essential amino acids in optimal quantities, so it is often combined with other plant sources of protein.

6. Pea protein. Pea protein is a plant source of protein obtained from yellow peas. It contains all nine essential amino acids, although the content of some amino acids, such as methionine, can be low. Pea protein is a good option for vegetarians and vegans.

7. Protein mixtures. Protein mixtures contain a combination of various sources of protein, such as serum protein, casein protein, soy protein and others. This provides a wide range of amino acids and a different speed of assimilation. Protein mixtures can be a good option for those who want to get advantages from several protein sources.

Section 3: Which protein is better for weight loss?

1. Wastein protein for rapid recovery and saturation. Whey -propelled protein, especially isolates, is an excellent choice for weight loss. It is quickly absorbed, which contributes to the rapid restoration of muscles after training. The high content of protein and the low content of fats and carbohydrates make it ideal to maintain muscle mass and reduce calories consumption. Studies have shown that the use of serum protein can increase the feeling of satiety and reduce the total calorie intake.

2. Casein protein for night recovery and prevention of catabolism. Casein protein, thanks to slow assimilation, can be useful for consumption before bedtime. It provides a constant flow of amino acids during the night, which helps to prevent the destruction of muscle tissue (catabolism) during sleep. Although casein protein is not so effective for quick recovery, it can contribute to the long -term maintenance of muscle mass.

3. Plant proteins for vegetarians and vegans. For those who adhere to a vegetarian or vegan diet, plant proteins, such as soy, pea and rice protein, are excellent alternatives. It is important to choose protein mixtures containing a combination of various plant sources of protein in order to ensure the receipt of all nine essential amino acids. Pea protein is often a preferred choice due to its good amino acid profile and easy digestibility.

4. Protein mixtures for an integrated approach. Protein mixtures containing a combination of serum protein, casein protein and plant proteins can be a good choice for those who want to get advantages from several sources of protein. They provide a wide range of amino acids and a different speed of assimilation, which can contribute to both rapid recovery after training and maintaining muscle mass for a long time.

5. The choice of protein depending on individual needs and preferences. The best protein for weight loss depends on individual needs and preferences. It is important to consider factors such as:

   • Allergies and intolerance: If you have an allergy to dairy products, choose egg, soy, rice or pea protein. If you have lactose intolerance, choose isolate serum protein or plant proteins.
   • Dietary preferences: If you are a vegetarian or vegan, choose vegetable proteins.
   • Use time: Serum protein is well suited for use after training, and casein protein is before bedtime.
   • Taste and texture: Choose a protein that you like and has a pleasant texture.

Section 4: How to use protein for weight loss

1. Replacing one meal with a protein cocktail. Replacing one meal with a protein cocktail can help reduce calorie intake and increase protein intake. This is especially useful for those who have difficulty cooking healthy food or someone has little time. It is important to choose protein cocktails that contain a sufficient amount of protein (20-30 grams) and little sugar. You can also add fruits, vegetables and healthy fats to cocktails to increase nutritional value.

2. The use of protein after training. The use of protein after training helps to restore muscles and promotes their growth. It is recommended to use 20-30 grams of protein within 30-60 minutes after training. Serum protein is an excellent choice for use after training, as it is quickly absorbed and contains all nine essential amino acids.

3. Adding protein to ordinary dishes. Adding protein to ordinary dishes can help increase the feeling of satiety and reduce the total calorie intake. Protein powder can be added to oatmeal, yogurt, soups, salads and pastries. You can also add foods rich in protein to dishes, such as chicken, fish, legumes and nuts.

4. Distribution of protein consumption during the day. It is recommended to distribute protein intake during the day, and not use the entire amount of protein in one meal. This helps to maintain a constant level of blood amino acids and contributes to a more effective restoration and growth of muscles. Try to eat 20-30 grams of protein with each meal.

5. The combination of protein with physical exercises and a balanced diet. Protein is an important component of a healthy lifestyle, but it is not a magical means for weight loss. To achieve the best results, it is necessary to combine the use of protein with regular physical exercises and a balanced diet. Regular physical exercises help burn calories and strengthen muscles, and a balanced diet provides the body with all the necessary nutrients.

Section 5: side effects and precautions

1. Possible side effects of protein additives. The use of protein additives is usually safe, but in some cases side effects can occur, such as:
