Slimming: efficiency, safety and scientific foundations

I. Review of dietary supplements for weight loss: types and mechanisms of action

Biologically active additives (dietary supplements), positioned as means for weight loss, are an extensive and heterogeneous category of products. They often contain combinations of vitamins, minerals, plant extracts, amino acids and other ingredients declared as contributing to weight loss, reduction of appetite, acceleration of metabolism or burning fat. However, it is important to understand that the regulation of dietary supplements is much less strict than the regulation of drugs, which requires a critical approach to evaluating their effectiveness and safety.

Consider the main types of dietary supplements for weight loss and the principles of their alleged action:

1. Suppressors of appetite:

These dietary supplements are aimed at reducing the feeling of hunger and increasing the feeling of saturation, which theoretically should lead to a decrease in calories consumption. The mechanisms of action vary depending on the ingredients:

• Fiber (soluble and insoluble): Soluble fiber, such as glucmannan, psillium and pectin, absorbs water in the stomach, forming a gel -like mass. This increases the volume of food in the stomach, slows down its emptying and promotes a feeling of satiety. Insoluble fiber, although it does not have such expressed absorbing properties, also helps to fill the stomach and normalize the intestinal function.
• Reverse capture of serotonin and norepinephrine (Sines/SNRIS – Plant analogues): Some plant extracts, such as 5-HTP (5-hydroxitriptophanes), argue that they increase serotonin levels in the brain. Serotonin is a neurotransmitter who is involved in the regulation of mood, appetite and sleep. An increase in the level of serotonin can theoretically lead to a decrease in craving for carbohydrates and a decrease in appetite. However, it is important to note that the efficiency and safety of plant analogues of Sines/Snris in weight loss are often not sufficiently studied, and their effect on the level of neurotransmitters can be insignificant or unpredictable.
• Preparations affecting the level of glucose in the blood: Some dietary supplements contain ingredients, which are claimed to help stabilize the level of glucose in the blood. Sharp jumps and falls of glucose levels can lead to hunger attacks and craving for sweet foods. Chrome is one of the minerals, which is sometimes added to dietary supplements for this purpose. It participates in glucose and insulin metabolism. However, studies of its effectiveness in weight loss gave conflicting results.
• Products containing a high amount of protein: Protein has a high saturative ability. Bades containing protein concentrates or isolates (for example, serum protein, casein, soy protein) can be used to increase protein consumption and reduce hunger. However, an increase in protein consumption in itself does not guarantee weight loss, and it is necessary to take into account the total calorie of the diet.

2. Thermogenic and metabolism stimulants:

Thermogenics are substances that are supposed to increase heat production in the body and accelerate metabolism, which leads to an increase in calories. Often they contain stimulants that increase heart rate and blood pressure.

• Caffeine and other stimulants: Caffeine is the most common stimulant used in dietary supplements for weight loss. It stimulates the central nervous system, increases the level of adrenaline and norepinephrine, which can lead to an increase in thermogenesis and energy consumption. Other stimulants, such as Sinefrin (obtained from a bitter orange), Yochimbin and Guarana, are also used in thermogenics. However, it is important to consider that stimulants can cause side effects, such as anxiety, insomnia, a rapid heartbeat and an increase in blood pressure.
• Green tea extract (EGCG): Green tea extract contains epallocatechin Gallat (EGCG), which is a powerful antioxidant. Some studies have shown that EGCG can help increase thermogenesis and oxidation of fats, especially in combination with caffeine. However, additional studies are needed to confirm these effects and determine the optimal dosages.
• Capsaicin: Capsaicin is an active compound contained in Chile pepper. It stimulates thermogenesis and can increase energy consumption. Some studies have shown that capsaicin can also reduce appetite. However, its efficiency in weight loss can be modest, and it can cause discomfort in the gastrointestinal tract.
• L-Carnitin: L-carnitine is an amino acid that is involved in the transport of fatty acids in mitochondria, where they are oxidized for energy. Theoretically, an increase in the level of L-carnitine should lead to an increase in fat burning. However, studies of its effectiveness in weight loss gave conflicting results.

3. Fat and carbohydrates blockers:

These dietary supplements are aimed at reducing the absorption of fats and carbohydrates in the intestines, which leads to a decrease in calories consumption.

• Hitosan: Chitosan is a polysaccharide obtained from crustacean shells. It is associated with fats in the digestive tract, preventing their absorption. However, its efficiency in weight loss remains controversial, and it can cause side effects, such as bloating and diarrhea.
• White beans extract (alpha-amylase inhibitor): White beans extract contains an alpha-amilase inhibitor, an enzyme that breaks down starch into simple sugar. By blocking alpha-amilasis, white beans extract can reduce carbohydrate absorption. However, its efficiency in weight loss can be limited, and it can cause side effects, such as gases and bloating.
• Orlistat (drug, sometimes unlawfully included in dietary supplements): Orlistat is a drug, and not a dietary supplement that blocks the enzyme lipaz that breaks down fats in the intestines. It is released according to the prescription of the doctor and has proven effectiveness in weight loss. However, its inclusion in dietary supplements is illegal and dangerous.

4. Diuretics (diuretics) and laxatives:

Some dietary supplements for weight loss contain diuretics and laxatives, which lead to the loss of water and the contents of the intestine, which can create the illusion of weight loss. However, this weight loss is temporary and is not related to the loss of fat mass. In addition, diuretics and laxatives can cause dehydration, electrolyte imbalance and other serious side effects.

• Herbal diuretics: Some herbs, such as dandelion, nettles and parsley, have a diuretic effect.
• Laxative herbs: Some herbs, such as Senna, Krushin and Aloe, have a laxative effect.

5. Probiotics:

Probiotics are living microorganisms, which are believed to have a beneficial effect on the health of the intestine. Some studies have shown that probiotics can help reduce weight and improve metabolism. However, additional studies are needed to confirm these effects and determine the optimal strains and dosages.

II. Efficiency of dietary supplements for weight loss: review of scientific data

The effectiveness of dietary supplements for weight loss is the subject of constant discussions and scientific research. It is important to understand that many dietary supplements are not subjected to strict clinical trials necessary to confirm their effectiveness and safety before they go on sale. As a result, evidence of their effectiveness is often limited, contradictory or absent at all.

When assessing the effectiveness of dietary supplements for weight loss, the following factors must be taken into account:

• Quality of research: Many studies of dietary supplements for weight loss have disadvantages in design, such as small sample size, lack of a control group or short duration. In addition, some studies are financed by dietary supplements, which can create bias.
• Variability of the results: The research results of dietary supplements for weight loss are often very different. Some studies show a slight weight loss, while others do not find any effect.
• Individual differences: The effect of dietary supplements for losing weight can vary greatly depending on the individual characteristics of the body, such as genetics, age, gender, state of health and lifestyle.
• Influence on the lifestyle: Some dietary supplements for weight loss can have an indirect effect on a lifestyle, for example, by suppressing appetite, which can lead to a decrease in calories consumption. However, it is important to understand that changes in lifestyle, such as compliance with a healthy diet and regular physical exercises, are key factors in achieving and maintaining a healthy weight.

Consider the scientific data on the effectiveness of some popular ingredients used in dietary supplements for weight loss:

• Caffeine: Caffeine can have a small stimulating effect on metabolism and promote fat burning. However, its effect is usually small and can decrease over time with regular use.
• Green tea extract (EGCG): Some studies have shown that EGCG can contribute to a slight increase in thermogenesis and oxidation of fats. However, its effect can be insignificant and depend on the dosage and individual characteristics of the body.
• Glucomanan: Glucomannan is a soluble fiber that can increase the feeling of saturation and reduce appetite. Some studies have shown that it can contribute to a slight weight loss.
• Hitosan: Evidence of chitosan efficiency in weight loss is limited and contradictory. Some studies have shown that it can contribute to a slight decrease in fat absorption, but its effect is usually small.
• White beans extract: Some studies have shown that white beans extract can contribute to a slight decrease in carbohydrate absorption. However, its effect can be limited, and it can cause side effects.
• L-Carnitin: Evidence of the efficiency of L-carnitine in weight loss is limited and contradictory. Some studies have shown that it can contribute to a slight increase in fat burning, but its effect is usually small.
• Chromium: Evidence of chromium efficiency in weight loss is limited and contradictory. Some studies have shown that it can contribute to a slight improvement in glucose metabolism, but its effect is usually small.

In general, scientific data indicate that most dietary supplements for weight loss have limited effectiveness. They can have a slight effect on weight, but their effect is usually not significant and may depend on the individual characteristics of the body. It is important to understand that dietary supplements are not a miraculous means for losing weight and cannot replace a healthy lifestyle, including a balanced diet and regular physical exercises.

III. Safety safety for weight loss: risks and side effects

The safety of dietary supplements for weight loss is a serious problem. Unlike drugs, dietary supplements are not subjected to strict clinical trials necessary to confirm their safety before they go on sale. As a result, many dietary supplements may contain ingredients that have not been carefully studied for safety, or contain substances not indicated on the label.

When assessing the safety of dietary supplements for weight loss, the following risks must be taken into account:
