Dietary diets for weight loss: we analyze popular means and their effectiveness
Dietary dietary supplements, or biologically active additives, are an extensive and often contradictory category of products promising to reduce weight. The market is saturated with offers from herbal extracts to synthetic compounds, each of which declares its unique advantages. Understanding the composition, mechanism of action and potential risks associated with these additives is crucial for making a reasonable decision on their use. This article examines in detail the various categories of dietary supplements, their active ingredients, the alleged mechanisms of action, scientific evidence of effectiveness and safety, as well as potential side effects and interactions with drugs.
1. Categories of dietary supplements for weight loss and their mechanisms of action:
Dietary supplements for weight loss can be conditionally divided into several categories depending on their alleged mechanism of action:
-
Thermogenics: These additives are aimed at increasing thermogenesis, the process of heat production in the body, which leads to an increase in calories. Often contain stimulants, such as caffeine, green tea extract, synephrine and Evodiamine.
- Caffeine: The stimulator of the central nervous system, which increases energy that improves concentration and stimulates lipolysis (breakdown of fats). The effectiveness of caffeine as a means for weight loss, but can temporarily increase metabolism and reduce appetite.
- Green tea extract (EGCG): It contains polyphenols, especially epallocatechin Gallat (EGCG), which has antioxidant properties and can contribute to thermogenesis and oxidation of fats. Studies show that EGCG in combination with caffeine can slightly improve the results of losing weight.
- Sinefrin: The analogue of Ephedrine stimulates adrenergic receptors, increasing lipolysis and thermogenesis. Sinefrin’s efficiency in weight loss has not yet been well studied, and there is a risk of side effects, such as increasing blood pressure and rapid heartbeat.
- Evodiamine: Received from the plant of Evodia Rutaecarpa, can increase body temperature and increase energy consumption. Evidence of Evodiamine’s effectiveness as a means for weight loss is limited, and additional studies are needed.
-
Carbohydrate blockers: These additives contain substances that prevent digestion and absorption of carbohydrates in the intestines.
- White beans extract (Phaseolus vulgaris): Contains an inhibitor of alpha-amylase, an enzyme that breaks down starch. Blocking alpha-amilasis, white beans extract can reduce the amount of carbohydrates absorbed by the body, thereby reducing calorie content. Studies show that white beans extract can contribute to a moderate weight loss in combination with diet and physical exercises.
- Hitosan: They get crustaceans from exoskeletons, binds fats in the digestive tract, preventing their absorption. The effectiveness of chitosan in weight loss remains controversial, and the research results are contradictory.
-
Fat blockers: Like carbohydrate blockers, these additives interfere with the absorption of fat fat.
- Orlistat: A pharmaceutical drug, accessible by a doctor’s prescription, inhibits lipaza, an enzyme that breaks down fats in the intestines. Orlistat is one of the most studied means for weight loss, and it is proved that it is effective in reducing weight in combination with a low fat diet. However, the orlistat can cause unpleasant side effects, such as steator (fat stool) and fecal incontinence.
-
Suppliers of appetite: These additives contain substances that suppress the feeling of hunger and increase the feeling of satiety, thereby reducing the consumption of calories.
- Glucomanan: Soluble fiber obtained from the roots of the plant of the end. Glucomannan absorbs water in the stomach, forming a gel -like mass that increases the feeling of satiety and slows down the emptying of the stomach. Studies show that glucomannan can help reduce weight in combination with diet and physical exercises.
- 5-HTP (5-hydroxyryptophan): The precursor of serotonin, a neurotransmitter who is involved in the regulation of mood, appetite and sleep. 5-HTP can increase the level of serotonin, which leads to a decrease in appetite and a decrease in calories consumption.
- HODADY Gordoni: The plant growing in South Africa was traditionally used to suppress appetite. It is believed that Hoodia contains a P57 molecule, which can affect the hypothalamus, part of the brain that is responsible for the regulation of hunger. However, the effectiveness and safety of Hoodia Gordonii as a means for weight loss have not been sufficiently studied.
-
Accelerators Metabolism: These additives say that they increase the rate of metabolism, allowing the body to burn more calories at rest.
- L-Carnitin: An amino acid that plays an important role in the transportation of fatty acids to mitochondria, where they are oxidized for energy. It is assumed that L-carnitine can improve fat metabolism and increase endurance during physical exertion. However, studies did not show convincing evidence of the effectiveness of L-carnitine as a means for weight loss.
- CLA (conjugated linoleic acid): A group of fatty acids that can affect the metabolism of fats and proteins. Some studies show that CLA can help reduce fat mass and increase muscle mass, but additional studies are needed to confirm these results.
-
Diuretics and laxatives: These additives can lead to short -term weight loss by eliminating fluid from the body and accelerating the transit of food through the intestines. However, this effect is temporary and does not lead to a real decrease in fat mass. The use of diuretics and laxatives for weight loss can be dangerous and lead to dehydration, electrolyte disorders and other serious side effects.
2. Scientific evidence of the effectiveness of dietary supplements for weight loss:
It is important to critically evaluate the scientific evidence of the effectiveness of dietary supplements for weight loss. Many additives have limited or conflicting scientific data confirming their declared advantages. Key factors that should be taken into account when evaluating effectiveness:
- Quality of research: Clinical trials should be randomized, placebo-controlled and double blind, in order to minimize bias and ensure the reliability of the results.
- Sample size: Studies with a large number of participants give more reliable results.
- Duration of research: Long -term research is necessary to assess the stability of the effect and potential long -term risks.
- Conflict of interest: It is important to consider the sources of research financing, since research financed by manufacturers of additives can be prone to positive results.
Despite numerous studies, only a few dietary supplements have convincing evidence of effectiveness. Some additives, such as green tea extract, white beans extract and glucmannan, showed moderate results in combination with diet and physical exercises. However, the effect of these additives is usually small, and they are not a magical means for weight loss. Other additives, such as Hoodia Gordonii and Sinefrin, have limited or conflicting evidence of effectiveness and may represent a health risk.
3. Safety of dietary supplements for weight loss and potential side effects:
The safety of dietary supplements for weight loss is a serious problem. Unlike pharmaceuticals, dietary supplements are not subject to strict verification and control of regulatory authorities such as FDA (US Sanitary Supervision of the quality of food and US medicines). This means that the composition, cleanliness and efficiency of dietary supplements can vary significantly, and consumers may not always be sure that they receive what is indicated on the label.
Potential side effects of dietary supplements for weight loss include:
- Gastrointestinal disorders: Nausea, vomiting, diarrhea, constipation, bloating.
- Cardiovascular problems: Increasing blood pressure, rapid heartbeat, arrhythmia.
- Disorders of the nervous system: Insomnia, anxiety, irritability, headaches.
- Liver damage: Hepatitis, liver failure.
- Interactions with drugs: Bades can interact with drugs, affecting their effectiveness or increasing side effects.
It is especially dangerous to use dietary supplements containing stimulants, such as Sinefrin and Ephedra, as they can cause serious cardiovascular complications. Bades containing diuretics and laxatives should also be avoided, as they can lead to dehydration and electrolyte disorders.
It is important to remember that “natural” does not always mean “safe”. Many herbal ingredients in dietary supplements can cause side effects and interact with drugs.
4. Intections of dietary supplements for weight loss with drugs:
Literation dietary supplements can interact with various drugs, affecting their effectiveness and safety. It is important to consult a doctor or a pharmacist before taking any dietary supplements, especially if you take any drugs on a prescription or without a prescription.
Examples of potential interactions:
- Anticoagulants (warfarin): Some dietary supplements, such as vitamin E and fish oil, can enhance the effect of anticoagulants and increase the risk of bleeding.
- Antidepressants (SIOS): 5-HTP can interact with the antidepressants of SIOS (selective inhibitors of the reverse capture of serotonin), increasing the risk of serotonin syndrome, a potentially dangerous state, characterized by anxiety, excitement, rapid palpitations and other symptoms.
- Diabetes Medicines: Some dietary supplements, such as chrome and alpha-lipoic acid, can affect blood sugar and increase the effect of drugs for diabetes, increasing the risk of hypoglycemia (low blood sugar).
- Belongation medicines: Stimulating dietary supplements, such as caffeine and synephrine, can increase blood pressure and reduce the effectiveness of medicines for blood pressure.
5. Recommendations for the safe use of dietary supplements for weight loss:
If you consider the possibility of using dietary supplements for weight loss, it is important to follow the following recommendations:
- Consult a doctor: Before you start taking any dietary supplements, consult a doctor or pharmacist to make sure that they are safe for you and will not interact with your medicines.
- Choose products from reliable manufacturers: Look for products from well -known manufacturers who adhere to strict quality standards and undergo independent testing.
- Read the labels carefully: Make sure you understand the composition of the product, the recommended dosage and potential side effects.
- Start with a low dose: Start with a low dose and gradually increase it, if necessary, following how your body reacts to the additive.
- Do not exceed the recommended dosage: Exceeding the recommended dosage can increase the risk of side effects.
- Do not take a few dietary supplements at the same time: Reception of several dietary supplements can simultaneously increase the risk of interaction and side effects.
- Stop taking it if you have side effects: If you have any side effects, immediately stop taking the additive and consult a doctor.
- Do not rely only on dietary supplements: Literation dietary supplements should be used in combination with a healthy diet and regular physical exercises. They are not a replacement for a healthy lifestyle.
6. Alternative approaches to weight loss:
The most effective and safe way to reduce weight is a combination of a healthy diet and regular physical exercises.
- Healthy diet: Focus on the use of whole, unprocessed products, such as fruits, vegetables, whole grain products, low -fat proteins and healthy fats. Limit the consumption of processed products, sugar, saturated and trans fats.
- Regular physical exercises: Strive at least 150 minutes of moderate intensity or 75 minutes of intensive aerobic activity per week, as well as for strength training at least twice a week.
- Full dream: The lack of sleep can disrupt the hormonal balance and lead to an increase in appetite and craving for unhealthy foods.
- Stress management: Stress can lead to overeating and weight gain. Find healthy ways to cope with stress, such as yoga, meditation or walking in nature.
- Professional help: If it is difficult for you to lose weight yourself, seek help from a doctor, a nutritionist or a certified coach.
7. Regulation of dietary supplements for weight loss in various countries:
The regulation of dietary supplements for weight loss varies significantly in different countries. In the United States, dietary supplements are regulated as food products, and not as drugs, which means that they are not subject to strict check and control by FDA. In Europe, dietary supplements are also regulated as food products, but there are more stringent safety and marking requirements. In some countries of Asia, such as China and India, the regulation of dietary supplements can also be less strict than in Europe and the USA.
The absence of uniform regulation standards creates problems for consumers, since the composition, cleanliness and efficiency of dietary supplements can vary significantly depending on the country of origin.
