The problem of excess weight becomes most pressing in the spring and on the eve of the upcoming beach season. It is at this time that figure flaws become most relevant and visible. For the same reason, in the lives of people losing weight, there is a real struggle for ideal forms: be it sports, strength training or diet. And, of course, a wide variety of means come to their aid, one of which is soy protein (isolate). We will consider reviews about it, as well as information about the principle of its operation, in this article.
What is Soy Protein Isolate?
During the weight loss process, many people go on a diet. To do this, they try to reduce the maximum allowable number of calories per day and get rid of all sweets and starchy foods. And sometimes very healthy, but, in their opinion, high-calorie foods become a potential victim of those losing weight. Examples are eggs, meat, cottage cheese and much more. But these products are considered the main suppliers of protein, which is so beneficial for the body. And when all you have left for breakfast, lunch and dinner is oatmeal, vegetables and buckwheat, and your hair and nails take on a deplorable appearance, there is a need to use soy protein isolate. So what is it?
Soy isolate is a special food supplement rich in protein or protein that we need. In this case, the product is isolated from the well-known soybean plant, or rather its concentrate. It is first mined and then further processed into powder form. In the process of such processing, carbohydrates and fats that are unloved by many are eliminated from soy protein isolate. The result is an ideal protein product, in which 90-95% is pure protein.
Benefits of use
The amino acid composition of the isolate is not complete, and in addition it contains a small amount of methionine - this amino acid is indispensable for the human athletic body. Soy filtrate used in sports nutrition is purified from harmful impurities - antinutrients, phytoestrogens. Therefore, using it, you don’t have to worry about your health and well-being.
Soy contains many beneficial natural substances and antioxidants for the human body. If a person who plays sports regularly takes soy filtrate, it will allow the body to increase the production of thyroid hormones and nitric oxide. Nitric oxide can improve blood flow in muscle tissue and strengthen. The soy product can be used during fasting or other periods.
It is also necessary to mention the fact that this product does not contain cholesterol, lactose, or various harmful fats. It is recommended for use by athletes during the period of “drying” the body, on a low-carbohydrate diet. Suitable for females. Soy protein filtrate helps enrich the athlete's diet. It is recommended to combine it with other types of protein to obtain a better effect.
Soy isolate can be used by athletes with allergic reactions to animal proteins, as well as athletes with lactase deficiency, since soy does not contain lactose
This bean product does not contain gluten, which is important for allergy sufferers. Soy is rich in Omega-3 and Omega-6 fatty acids and fiber
Fiber has a positive effect on the functioning of the gastrointestinal tract, as well as its microflora, and is capable of removing harmful substances from the body. - all detailed information.
Protein filtrate is capable of removing radionuclides and heavy metals from the body - they can provoke the formation of oncology. Bean products of this type contain a lot of lecithin. Lecithin has a positive effect on the entire body as a whole. It is very important for the full functioning of biological cell membranes, takes part in fat metabolism and cholesterol metabolism.
Soy contains a protease enzyme that promotes intensive protein breakdown. The isolate can be added to, in order to further enrich them with amino acids. It must be remembered that this is a legume plant, products from it do not harm the human body, as is commonly believed. The filtrate is equal in protein value to meat, so it is recommended for use in nutrition.
How quickly is it absorbed?
Despite its natural origin, soy protein (weight loss isolate) is absorbed much more slowly. For example, if you compare it with protein obtained from whey or dairy products (this is how casein is obtained). However, this natural component is perfectly tolerated and processed into the energy we need.
The exceptions are counterfeits and cheap varieties of the product, which are absorbed by only 40-60%. Therefore, when choosing a protein, you should pay attention to the manufacturer, year of manufacture and cost of the product. And, of course, its too low price is simply bound to alert you.
History of appearance
Technical isolate began to be produced starting in 1937 as a binding component of paper coatings and fire-fighting foam. Since about the 50s of the last century, the production of food concentrates has been established. Nowadays, isolate has become widespread in nutrition as a complete replacement for the main sources of protein in the diet.
In modern production, it is obtained in different ways, most often by extraction, precipitation or neutralization. At the final stage, the product is finished by spray drying, if necessary, enriched with calcium, granulated, etc.
Who uses isolate and for what purposes?
Soy protein isolate is used for weight loss. With its help, the lack of protein is compensated without harm to the body. It is also used by athletes who are interested in “drying out” the body or preserving muscle mass. He found his fans among vegetarians, as well as people suffering from lactose intolerance. Moreover, the isolate is actively used by believers who observe fasting.
How much protein do you need per day?
When using soy protein isolate, it is necessary to dose it correctly. That is why the box containing the product often contains a measuring cup or spoon. At the same time, a person’s daily need for protein depends on his lifestyle and the effect he plans to achieve. For example, an ordinary person who does not lead a sports lifestyle needs to consume at least 1-2 g of a nutritional supplement per 1 kg of his weight per day.
Athletes have to use this type of supplement at a rate of 15-30 g per meal. And since most athletes adhere to fractional meals (eat little, but several times a day), there can be approximately 8-9 such approaches.

What do you need to lose weight?
According to experienced weight loss people, if your goal is to lose weight beyond soy protein, you need to do a tough audit of your daily foods. In particular, you should reduce the number of carbohydrates and fats, but be sure to maintain protein foods in your diet.
If this rule is not followed, the weight loss process will be extremely slow. Moreover, the risk of sagging muscles and visual sagging of the skin increases significantly, which does not look very attractive, you must agree. So consuming soy protein isolate is a necessary measure for those who want to lose weight without spoiling their appearance.
What does the isolate contain?
In addition to protein, protein also contains a number of useful micro- and macroelements. They are a kind of antioxidants and help normalize metabolism. With their help, there is a gradual increase in thyroid hormones, which are responsible for the full functioning of the thyroid gland. Among the beneficial components contained in soy protein, we can highlight those shown in the photo. This is some calcium, sodium, magnesium and other elements.
Chemical properties for the body
The main purpose of soy isolate is to supply the body with protein. Being an alternative to animal proteins, this product has a number of unique properties:
- provides the necessary material to the muscles;
- has anti-catabolic properties (inhibits the process of protein breakdown);
- prevents the destruction of muscle tissue during training, as part of a low-calorie diet;
- ensures the growth of “lean” muscle mass during sports;
- maintains nitrogen balance in the body, increases the level of oxide of this substance;
- improves blood circulation and improves immunity;
- has a fat burning effect.
Protein isolate perfectly satisfies hunger, includes
metabolic processes in the body, maintains energy during heavy physical activity. For the weaker sex, this vegetable protein is of particular importance:
- normalizes hormonal levels;
- minimizes masculinization;
- maintains fluid level;
- tones the skin and muscles.
It contains fiber, useful for digestion, amino acids - glutamine, arginine, lysine, cysteine. The thyroid gland, with the support of the isolate, begins to produce more thyroid hormones needed by the body.
How to consume and prepare protein?
Soy protein is usually consumed in diluted form. To prepare it, just follow these simple steps:
- prepare the container;
- pour about 1-2 tbsp there. spoons of isolate;
- dilute the powder with 200 ml of water;
- shake to combine evenly.
Fitness fans add nuts, bananas and even raw oatmeal to this protein shake. The end result is a fairly satisfying drink that can compensate for the energy spent on training and moderate your appetite. If such supplements are used by age-old fighters against excess weight, then this drink should replace one of the meals, for example, breakfast or dinner.
It is noteworthy that you can use skim milk, yogurt or kefir as the basis for the cocktail. However, those who are lactose intolerant should not use these ingredients. In such cases, it is better to use freshly squeezed juice or water as a base. But it is also worth considering the fact that the water for such a drink should not be hot. Otherwise, the protein will simply coagulate and, of course, lose its original properties.
