Chapter 1: Understanding the world of dietary supplements for weight loss
Biologically active additives (dietary supplements) for weight loss are a wide range of products designed to accelerate the weight loss process. They vary in composition, mechanisms of action and effectiveness. Before considering specific products, it is important to understand the general categories and principles underlying their actions.
1.1. Categories of dietary supplements for weight loss:
- Thermogenics: These additives increase thermogenesis, that is, heat production in the body. This leads to an increase in calorie consumption and, potentially, to weight loss. Typical ingredients include caffeine, green tea extract, synephrine and capsaicin.
- Suppliers of appetite: These additives are aimed at reducing the feeling of hunger and increasing the feeling of satiety. They can act in various ways, for example, increasing the level of certain hormones affecting appetite, or increasing the volume of gastric contents. Examples include glucomannan, 5-HTP and Khudia Gordonia.
- Fat blockers: These additives prevent the absorption of fat from food in the intestines. They are associated with fats, forming complexes that are not digested and excreted from the body. The most famous fat blocker is Orlistat (Ksenical), which is a drug released according to the prescription. Some dietary supplements contain chitosan, which can also have a fatty effect, although its effectiveness is less proven.
- Carbohydrate blockers: These additives prevent the digestion of carbohydrates, reducing the number of calories that the body receives from carbohydrates. They often contain white beans extract, which inhibits the enzyme alpha amylase necessary for digestion of starch.
- Accelerators Metabolism: These additives are aimed at accelerating metabolism, that is, the speed at which the body burns calories. They often contain ingredients that are believed to stimulate the thyroid gland or increase energy production at the cellular level. Examples include iodine, selenium and coenzyme Q10.
- Detoxicators: These additives say that they cleanse the body of toxins and improve the general state of health, which, in turn, can contribute to weight loss. However, scientific evidence confirming the effectiveness of detoxification additives is limited.
- Addresses affecting blood sugar: These additives help stabilize blood sugar, which can reduce craving for sweets and improve appetite control. Examples include chromium, cinnamon and Berberin.
- Probiotics: These additives contain useful bacteria, which are believed to improve intestinal health. Some studies show that probiotics can affect weight, but additional studies are needed.
- Vitamins and minerals: Although vitamins and minerals are not directly additives for weight loss, they are important for the general state of health and can help maintain healthy weight. For example, vitamin D deficiency can be associated with an increased risk of obesity.
1.2. Action mechanisms:
Dietary dietary supplements act in various ways, depending on their composition. Some of the most common mechanisms include:
- Increase in energy consumption: Thermogenics increase energy consumption by increasing thermogenesis and metabolism.
- Reducing calorie consumption: Suppressors of appetite and blocks of fat and carbohydrates reduce calorie intake by reducing appetite or preventing calories from food from food.
- Improving metabolism: Metabolism accelerators increase the speed with which the body burns calories.
- Regulation of blood sugar: Addresses affecting blood sugar stabilize blood sugar, which can reduce the craving for sweets and improve appetite control.
- Improving intestinal health: Probiotics improve intestinal health, which can affect weight.
1.3. The effectiveness of dietary supplements for weight loss:
The effectiveness of dietary supplements for weight loss varies greatly. Some additives, such as Orlistat, have proven effectiveness in clinical studies, while other additives have limited or conflicting scientific evidence. It is important to note that no additive is a miraculous tool for weight loss, and they are most effective in combination with a healthy diet and regular physical exercises.
1.4. Safety safety for weight loss:
The safety of dietary supplements for weight loss also varies greatly. Some additives, such as caffeine, are safe for most people in moderate quantities, while other additives, such as ephedra, may have serious side effects. It is important to talk with your doctor before taking any dietary supplement for weight loss, especially if you have any diseases or you take any medicine. It is also important to buy dietary supplements from reliable manufacturers to make sure that they contain what is indicated on the label, and do not contain harmful impurities.
1.5. Bad regulation:
Unlike drugs, dietary supplements are not subject to strict control by regulatory authorities such as FDA (sanitary supervision of the quality of food and medicines) in the United States. This means that dietary supplement manufacturers are not required to prove the efficiency or safety of their products before they go on sale. FDA can take measures against dietary supplements only after they are recognized as unsafe. This emphasizes the importance of conducting your own research and the choice of dietary supplements among reliable manufacturers.
