Dietary diets for weight loss: myths and reality

Dietary diets for weight loss: myths and reality

Section 1: Understanding of dietary supplements and their regulation

1. What are dietary supplements (biologically active additives)?

   Bades are concentrated sources of nutrients (vitamins, minerals, amino acids, herbs and other plant components, probiotics, prebiotics, dietary fibers, etc.) designed to supplement the diet. They are produced in various forms, such as tablets, capsules, powders, liquids and bars. Bades are not drugs and are not intended for the treatment, diagnosis or prevention of diseases. Their goal is to replenish the deficiency of nutrients and maintain health.

2. Regulation of dietary supplements in Russia and other countries.

   In Russia, the turnover of dietary supplements is regulated by the Federal Service for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor). Before issuing the market, dietary supplements are subject to state registration, during which their safety and compliance with the established requirements are evaluated. The registration procedure includes documentation examination, laboratory tests and marking assessment. It is important to note that the registration of dietary supplements is not a guarantee of its effectiveness, but only confirms its compliance with security requirements.

   In other countries, the regulation of dietary supplements may vary significantly. In the United States, dietary supplements are regulated as food products, not medicines, and do not require preliminary approval of FDA (management for sanitary supervision of the quality of food and medicines). Manufacturers are required to ensure the safety of their products, but the responsibility for evidence of safety and efficiency lies with them, and not on the regulatory authority. In the European Union, the regulation of dietary supplements is harmonized, but individual countries can establish their own requirements for the content of some substances and labeling.

3. Bad labeling: what the consumer needs to know.

   Bad marking should contain the following information: product name, composition, information about the manufacturer, the date of manufacture and shelf life, storage conditions, recommendations on use, contraindications and warning. It is important to pay attention to the composition of the dietary supplement and check the presence of components that can cause allergic reactions or interact with the drugs taken. It is also necessary to take into account the recommended dose and not exceed it without consulting a doctor. The marking should be clear, selective and written in Russian. The presence of false or misleading information should alert the consumer.

4. Criteria for choosing high -quality dietary supplements.

   When choosing a dietary supplement, you should pay attention to the following factors:

   • Reputation manufacturer: Preference should be given to companies that have a good reputation in the market and comply with quality standards.
   • Availability of quality certificates: Some manufacturers voluntarily certify their products in accordance with international standards (for example, GMP – Good Manufactoring Practice).
   • Product composition: It is necessary to carefully study the composition of the dietary supplement and make sure that there are no doubtful or prohibited components.
   • The presence of clinical research: If the manufacturer claims the effectiveness of his product, it is advisable to check the availability of scientific research confirming these statements.
   • Consumer reviews: It is useful to familiarize yourself with the reviews of other consumers, but it should be remembered that reviews can be subjective and do not always reflect the real picture.
   • Consultation with a doctor or nutritionist: Before taking a dietary supplement, it is recommended to consult a doctor or nutritionist, especially if you have any diseases or you take medications.

Section 2: The main groups of dietary supplements for weight loss and their alleged mechanism of action

1. Thermogenics: caffeine, synephrine, green tea extract.

   • The mechanism of action: Thermogenics increase body temperature, accelerate metabolism and stimulate fat burning. Caffeine, for example, stimulates the central nervous system, increases the release of adrenaline and norepinephrine, which leads to an increase in energy consumption. Green tea extract contains catechins that have antioxidant properties and can contribute to fat oxidation. Sinefrin contained in Wine, also stimulates adrenergic receptors and can increase thermogenesis.
   • Efficiency (scientific data): The efficiency of thermogenes in weight loss is moderate. Studies show that caffeine and green tea extract can slightly increase energy consumption and contribute to weight loss, but these effects are usually small and can be temporary. Sinefrin can also affect weight, but its effectiveness and safety require further study.
   • Side effects and risks: Thermogenics can cause side effects, such as increased blood pressure, rapid heartbeat, insomnia, anxiety, headache and gastrointestinal tract disorders. People with cardiovascular diseases, hypertension, anxious disorders and other diseases should avoid taking thermogenics.

2. Carbohydrates and fat blockers: chitosan, white beans extract, eagleistat.

   • The mechanism of action: Blocks of carbohydrates and fats prevent the absorption of these nutrients in the intestines. Chitosan, for example, is associated with fats and forms complexes that are not digested and excreted from the body. White beans extract inhibits the enzyme alpha amylase, which breaks down carbohydrates, which leads to a decrease in their absorption. Orlistat is a drug, which is inhibited by a recipe that inhibits lipaza, an enzyme that breaks down fats, which also leads to a decrease in their absorption.
   • Efficiency (scientific data): The effectiveness of carbohydrates and fat blockers in weight loss is also moderate. Studies show that chitosan and white beans extract can slightly reduce the absorption of fats and carbohydrates, but these effects are usually small and do not lead to a significant weight loss. Orlistat is more effective, but it can cause side effects, such as diarrhea, steator (excretion of fat with feces) and violation of the absorption of fat -soluble vitamins.
   • Side effects and risks: Blocks of carbohydrates and fats can cause side effects, such as disorders of the gastrointestinal tract, including bloating, gas formation, diarrhea and constipation. Orlistat can also cause steator and violation of the absorption of fat -soluble vitamins (A, D, E, K), which requires additional intake of vitamin additives.

3. Suppliers of appetite: Glucomannan, 5-HTP, Hoodia Gordonii.

   • The mechanism of action: Suppressors of appetite reduce hunger and help reduce calorie intake. Glucomannan is a soluble fiber, which, when contacting water, swells in the stomach and creates a feeling of satiety. 5-HTP (5-hydroxitriptophanes) is the precursor of serotonin, neurotransmitter, which is involved in the regulation of appetite. Hoodia Gordonii is a plant that is claimed to contain a substance that suppresses appetite.
   • Efficiency (scientific data): Glucomannan is the most studied suppressor of appetite. Studies show that it can contribute to weight loss, but its effectiveness depends on the dose and duration of the reception. 5-HTP efficiency in weight loss requires further study. With regard to Hoodia Gordonii, scientific data on efficiency and safety are not enough.
   • Side effects and risks: Glucomannan can cause side effects, such as bloating, gas formation and constipation. 5-HTP can cause nausea, vomiting, diarrhea and headache. Hoodia Gordonii can cause side effects, such as increasing blood pressure and rapid heartbeat, but safety data is not enough.

4. Diuretics and laxatives: Senna, Krushin, Furosemide (forbidden).

   • The mechanism of action: Diuretics increase the elimination of fluid from the body, and laxatives accelerate intestinal motility and contribute to the removal of feces. These funds do not affect fat burning and do not lead to weight loss in the long term. Their use can only lead to a temporary reduction in body weight due to the loss of fluid and the contents of the intestine.
   • Efficiency (scientific data): Diuretics and laxatives are ineffective for weight loss. They can cause a temporary reduction in body weight due to the loss of fluid and the contents of the intestine, but this effect is not stable and does not lead to a decrease in fat mass.
   • Side effects and risks: Diuretics and laxatives can cause serious side effects, such as dehydration, electrolyte imbalance (violation of sodium, potassium and other electrolytes), muscle cramps, weakness, dizziness and impaired renal function. Long -term use of laxatives can lead to the dependence and violation of the normal functioning of the intestine. Furosemide is a drug and its use for weight loss is prohibited due to high risk of serious side effects.

5. Dietary supplements containing CLA (conjugated linoleic acid), L-carnitine, chrome.

   • The mechanism of action: CLA (conjugated linoleic acid) is a group of fatty acids, which is allegedly promotes fat and increase muscle mass. L-carnitine is an amino acid that is involved in the transport of fatty acids in mitochondria, where they are used to obtain energy. Chrome is a trace element that is involved in the regulation of blood sugar levels and, it is statement, reduces the craving for sweets.
   • Efficiency (scientific data): The effectiveness of Cla, L-carnitine and chromium in weight loss is controversial. Studies show that CLA can slightly contribute to a decrease in fat mass and an increase in muscle mass, but these effects are usually small and are not observed in all people. L-carnitine can improve sports indicators, but its effect on weight loss is minimal. Chrome can reduce the craving for sweets in some people, but its influence on weight is slightly.
   • Side effects and risks: Cla can cause side effects, such as disorders of the gastrointestinal tract, including nausea, vomiting and diarrhea. L-carnitine can cause side effects, such as nausea, vomiting, diarrhea and the smell of fish from the body. Chrome is usually considered safe, but in high doses can cause side effects, such as disorders of the gastrointestinal tract and headache.

Section 3: Myths about dietary supplements for weight loss

1. Myth: Bades are a safe alternative to drugs.

   Reality: Bades do not go through the same strict clinical trials as drugs. Although many dietary supplements contain natural ingredients, this does not guarantee their safety. Some dietary supplements may contain harmful substances that are not indicated on the label, or interact with drugs, which can lead to serious side effects. Always consult a doctor before taking any dietary supplements, especially if you have any diseases or you take medications.

2. Myth: Dans can quickly and easily solve the problem of excess weight.

Weight reduction is a complex process that requires a comprehensive approach, including proper nutrition, regular physical exercises and a healthy lifestyle. Bad can only be an addition to this approach, but they are not a replacement for a healthy lifestyle.

3. Myth: If dietary supplements are sold in a pharmacy, then it is safe and effective.

Before buying a dietary supplement in a pharmacy, you must carefully study the composition of the product, get acquainted with consumer reviews and consult a doctor or nutritionist.

4. Myth: Bades have no side effects.

   Reality: Many dietary supplements can cause side effects, especially with improper use or in the presence of individual intolerance to components. Side effects can be different, from mild disorders of the gastrointestinal tract to serious allergic reactions and disorders of the organs and systems.

5. Myth: The more dietary supplements, the better the result.

   Reality: An increase in dose of dietary supplements does not always lead to an improvement in the result and can, on the contrary, increase the risk of side effects. It is important to observe the recommended dose indicated on the packaging, and not exceed it without consulting a doctor.

Section 4: Reality: how dietary supplements can help (and when they are useless)

1. When dietary supplements can be useful in the process of losing weight (as an addition).

   • Filling a deficiency of nutrients: If a diet for weight loss limits the consumption of certain products or groups of products, dietary supplements can help to fill the deficiency of vitamins, minerals and other nutrients. For example, with a vegetarian or vegan diet, an additional intake of vitamin B12, iron and calcium may be required.
   • Metabolism support: Some dietary supplements, such as green tea extract and L-carnitine, can slightly support metabolism and contribute to fat burning, but their effectiveness is not significant and depends on the individual characteristics of the body.
   • Appetite control: Bades containing glucmannan or other soluble fibers can create a feeling of satiety and help control appetite, which can help reduce calorie intake.
   • Improving digestion: Bades containing probiotics and prebiotics can improve digestion and maintain a healthy intestinal microflora, which can have a positive effect on the process of losing weight.

2. When dietary supplements are useless and even harmful to weight loss.

   • Instead of a healthy diet and physical exercises: Bades cannot replace healthy nutrition and regular physical exercises. They can only be an addition to these basic components of the weight loss process.
   • If there are contraindications: In the presence of certain diseases or taking drugs, some dietary supplements can be contraindicated or caused by side effects.
   • In the absence of control by the doctor: Acceptance of dietary supplements without consulting a doctor can be dangerous, as the doctor can evaluate the state of health, identify contraindications and choose the optimal dose and dietary supplement composition.
   • In case of abuse: The abuse of dietary supplements, especially diuretics and laxatives, can lead to serious health consequences, such as dehydration, electrolyte imbalance and violation of the work of organs and systems.
   • When buying low -quality products: The purchase of dietary supplements from unverified suppliers or in dubious places can lead to the acquisition of a poor -quality product that may contain harmful substances or not correspond to the declared composition.

3. Badam alternatives: healthy nutrition, physical activity, consultation with a doctor and nutritionist.

   • Healthy nutrition: The basis of successful weight loss is a healthy diet, which includes the consumption of a sufficient amount of vegetables, fruits, whole grain products, low -fat protein and healthy fats. It is important to avoid processed products, sugar and saturated fats.
   • Physical activity: Regular physical exercises help to burn calories, strengthen muscles and improve the general state of health. It is recommended to combine aerobic exercises (running, swimming, cycling) with strength training.
   • Consultations with a doctor and nutritionist: Consultations with a doctor and a nutritionist help to develop an individual nutrition and training plan, taking into account the characteristics of the body, the state of health and the goal of losing weight. The doctor may exclude diseases that can cause excess weight, and the nutritionist will help to make a balanced diet and give recommendations for the choice of products.
