Effective dietary supplements for weight loss: what to choose?

Effective dietary supplements for weight loss: what to choose?

Section 1: Understanding of weight loss mechanisms and the role of dietary supplements

Losing weight is a complex physiological process that depends on a number of factors, including genetics, lifestyle, diet and level of physical activity. The creation of a calorie deficit is based when the body burns more calories than it consumes. This deficit makes the body use accumulated energy reserves, mainly in the form of fat, to maintain vital activity.

There is no “magic pill” for weight loss. A balanced diet and regular physical exercises are the basis of a healthy weight loss. However, biologically active additives (dietary supplements) can play an auxiliary role, potentially supporting and accelerating this process. It is important to understand that dietary supplements are not a replacement for a healthy lifestyle, but only with an addition to it.

Dietary dietary supplements for weight loss act in different ways. Some may suppress appetite, reducing hunger and helping to control the size of portions. Others can accelerate metabolism, increasing the number of calories burned by the body at rest. Still others can block the absorption of fats or carbohydrates from food, reducing the number of calories entering the body. Some dietary supplements can also affect the hormonal balance, improve insulin sensitivity or stimulate lipolysis (fat splitting).

However, the efficiency and safety of dietary supplements for weight loss vary. Some additives have scientific evidence of their effectiveness, while others do not have sufficient support from research. In addition, some dietary supplements can cause side effects or interact with medicines. Therefore, before taking any dietary supplement for weight loss, you need to consult a doctor or a qualified nutritionist.

Section 2: categories of dietary supplements for weight loss: review and mechanisms of action

Dietary supplements for weight loss can be divided into several main categories, depending on their mechanism of action:

• Thermogenics: These additives increase thermal products in the body, which leads to the acceleration of metabolism and burning more calories. Typical ingredients of thermogenics include caffeine, green tea extract, bitter orange extract (Sinefrin) and capsaicin (chili pepper extract). Caffeine stimulates the central nervous system, increasing the level of energy and accelerating metabolism. Green tea extract contains epigallocatechin Gallat (EGCG), an antioxidant that can also accelerate metabolism and promote fat burning. Sinefrin, similar in structure to ephedrine (forbidden substance), can also stimulate thermogenesis, but its effectiveness and safety are controversial. Capsaicin activates TRPV1 receptors involved in the thermogenesis and suppression of appetite.

• Suppliers of appetite: These additives help reduce hunger and control portions. They can act in different ways: increase the feeling of satiety, influence hormones that regulate appetite, or slow down the emptying of the stomach. Examples include fiber (psillium, glucomannan), 5-HTP (5-hydroxitriptophanes), and Garcinia Cambodian. Fiber absorbs water in the stomach, increasing the volume and creating a feeling of satiety. Glucomannan, especially an effective form of fiber, can significantly slow down the emptying of the stomach. 5-HTP is the predecessor of serotonin, a neurotransmitter who plays a role in the regulation of mood and appetite. Garcinia Cambodia contains hydroxilimonic acid (HCA), which is believed to block the enzyme involved in the synthesis of fats and increases the level of serotonin.

• Fat and carbohydrates blockers: These additives prevent the absorption of fat or carbohydrates from food, reducing the number of calories entering the body. Examples include chitosan (fat block) and white beans extract (carbohydrate blocker). Chitosan is a polysaccharide obtained from the shells of crustaceans, which is associated with fats in the digestive tract, preventing their absorption. White beans extract contains phaseolamine, alpha-amilase inhibitor, enzyme that breaks down carbohydrates. Inhibiting alpha amylase, white beans extract slows down the digestion of carbohydrates, reducing the amount of glucose entering the blood.

• Accelerators Metabolism: These additives increase metabolism, increasing the number of calories burned by the body at rest. Examples include L-carnitine, coenzyme Q10 (COQ10) and iodine. L-carnitine plays an important role in the transport of fatty acids in mitochondria, where they are burned for energy. COQ10 is involved in the production of energy in cells and can improve metabolic function. Iodine is necessary for the production of thyroid hormones that regulate metabolism.

• Diuretics and laxatives: Some dietary supplements contain diuretics (diuretics) or laxative components that lead to temporary loss of weight due to the removal of water or feces from the body. However, this is not a real weight loss and can be dangerous to health, leading to dehydration and imbalance of electrolytes. Such additives should be avoided.

Section 3: detailed review of popular dietary supplements for weight loss: evidence, efficiency and safety

The following is a detailed review of some popular dietary supplements for weight loss, including analysis of scientific evidence, evaluating effectiveness and consideration of potential risks and side effects:

• Caffeine: Caffeine is a stimulant of the central nervous system, which is contained in coffee, tea, mat and many energy drinks and dietary supplements. It can increase energy levels, improve concentration and accelerate metabolism. Caffeine can also suppress appetite and stimulate thermogenesis.

  • Proof: Numerous studies have shown that caffeine can increase energy consumption and promote fat burning. However, the effect of caffeine for losing weight can be small and vary depending on individual sensitivity and dosage.

  • Efficiency: Caffeine can be effective as a short -term means to increase metabolism and suppress appetite. However, prolonged use of caffeine can lead to tolerance, decrease in efficiency and side effects.

  • Safety: Caffeine can cause side effects, such as insomnia, anxiety, nervousness, rapid heartbeat and stomach disorder. High doses of caffeine can be dangerous for people with cardiovascular diseases, anxiety or other health problems. The recommended daily dose of caffeine is not more than 400 mg for adults.

• Green tea extract: Green tea extract contains epigallocatechin Gallat (EGCG), an antioxidant that can accelerate metabolism and promote fat burning. EGCG can also improve insulin sensitivity and reduce inflammation.

  • Proof: Some studies have shown that green tea extract can increase energy consumption and promote fat burning, especially in combination with caffeine. However, other studies did not reveal significant effects of green tea extract on weight loss.

  • Efficiency: Green tea extract can be effective as an auxiliary tool for weight loss, especially in combination with other strategies, such as diet and physical exercises.

  • Safety: Green tea extract is usually considered safe, but can cause side effects, such as stomach disorder, nausea and headache. In rare cases, green tea extract can cause liver damage. The recommended daily dose of EGCG is not more than 800 mg.

• Garcinia Cambodia: Garcinia Cambodian is a tropical fruit containing hydroxilimic acid (HCA). HCA is believed to block the enzyme involved in the synthesis of fats, and increases the level of serotonin.

  • Proof: The results of the research of Garcinia Cambodia are contradictory. Some studies have shown that HCA can contribute to a slight weight loss, while other studies have not revealed a significant impact on weight loss.

  • Efficiency: The effectiveness of Garcinia Cambodia as a means for weight loss remains in question.

  • Safety: Garcinia Cambodian is usually considered safe, but can cause side effects, such as stomach disorder, nausea and headache. In rare cases, Garcinia Cambodia can cause liver damage.

• Glucomanan: Glucomannan is a soluble fiber obtained from the roots of the plant of the cow. Glucomannan absorbs water in the stomach, increasing the volume and creating a feeling of satiety. It can also slow down the emptying of the stomach and reduce blood cholesterol.

  • Proof: Studies have shown that glucomannan can help reduce weight, especially in combination with diet and physical exercises.

  • Efficiency: Glucomannan can be effective as a means of suppressing appetite and weight control.

  • Safety: Glucomannan is usually considered safe, but can cause side effects, such as bloating, gases and constipation. It is important to take glucmannan with a lot of water to avoid suffocation or clogging of the esophagus.

• Hitosan: Chitosan is a polysaccharide obtained from crustacean shells. Chitosan is associated with fats in the digestive tract, preventing their absorption.

  • Proof: Some studies have shown that chitosan can contribute to a slight weight loss. However, other studies did not reveal the significant influence of chitosan on weight loss.

  • Efficiency: The effectiveness of chitosan as a means for weight loss remains in question.

  • Safety: Chitosan can cause side effects, such as stomach disorder, constipation and allergic reactions in people with allergies to crustaceans. Chitosan can also interact with some drugs.

• L-Carnitin: L-carnitine plays an important role in the transport of fatty acids in mitochondria, where they are burned for energy.

  • Proof: L-carnitine research results are contradictory. Some studies have shown that L-carnitine can improve physical performance and promote fat burning, while other studies have not revealed a significant effect on weight loss.

  • Efficiency: The effectiveness of L-carnitine as a means for weight loss remains in question.

  • Safety: L-carnitine is usually considered safe, but can cause side effects, such as stomach disorder, nausea and diarrhea. High doses of L-carnitine can cause fish smell.

• White beans extract: White beans extract contains phaseolamine, alpha-amilase inhibitor, enzyme that breaks down carbohydrates. Inhibiting alpha amylase, white beans extract slows down the digestion of carbohydrates, reducing the amount of glucose entering the blood.

  • Proof: Some studies have shown that white beans extract can help reduce weight and reduce fat deposits, especially in combination with a low carbohydrate diet.

  • Efficiency: White beans extract can be effective as an auxiliary means to control weight and reduce blood sugar.

  • Safety: White beans extract are usually considered safe, but can cause side effects, such as bloating, gases and diarrhea.
