Dietary diets for weight loss: reviews and side effects

I. Variety of dietary supplements for weight loss: action mechanisms and popular ingredients

1. Classification of dietary supplements for weight loss depending on the mechanism of action:

Dietary supplements for weight loss (biologically active additives) are an extensive and diverse group of products designed to accelerate the process of weight loss. Their popularity is due to the desire for the rapid and easy achievement of the desired figure. However, it is important to understand that dietary supplements are not drugs and do not pass strict clinical trials as medicines. The effectiveness and safety of many of them remain the subject of discussions.

Depending on the mechanism of action, dietary supplements for weight loss can be classified into several main groups:

• Girosguards (thermogenics): These additives are designed to increase body temperature and accelerate metabolism, thereby increasing calorie consumption and contributing to burning fat. Key ingredients in this group include caffeine, green tea extract, synephrine (extract of the orange), capsaicin (chili pepper extract), and yochimbin. The mechanism of action is based on the stimulation of the nervous system and the activation of lipolysis processes (splitting of fats).

  • Caffeine: It stimulates the central nervous system, increases the level of energy, improves concentration and attention. It also promotes thermogenesis and lipolysis. Side effects can include insomnia, anxiety, rapid heartbeat, headaches and digestive disorders.
  • Green tea extract (EGCG): Contains polyphenols, in particular epallocatechin Gallat (EGCG), which have antioxidant and thermogenic properties. It is assumed that EGCG increases oxidation of fats and accelerates metabolism. Possible side effects: insomnia, irritability, digestive disorders.
  • Sinefrin: It is a stimulant, structurally similar to Ephedrine. It is believed that Sinefrin stimulates lipolysis and thermogenesis, however, its effectiveness and safety are disputed. Side effects may include an increase in blood pressure, rapid heartbeat, anxiety and headaches. The combination of synephrine with caffeine is especially dangerous.
  • Capsaicin: Contained in chili pepper. Capsaicin stimulates thermogenesis, reduces appetite and improves fat oxidation. It can cause side effects, such as heartburn, stomach disorders, nausea and diarrhea.
  • Yohimbine: Alfa-2 adrenergic shutter, which is believed to help burning fat, especially in problem areas (stomach, hips). It can cause serious side effects, such as anxiety, an increase in blood pressure, a rapid heartbeat, headaches and insomnia. The use of yocimbine requires caution and consultation with a doctor.

• Carbohydrate blockers: These additives prevent the absorption of carbohydrates in the intestines, thereby reducing the calorie content of food and contributing to weight loss. The most common ingredient is the white beans extract (Phaseolus vulgaris). This extract contains an inhibitor of alpha amylase, an enzyme that breaks down starch. Blocking alpha-amilasis, the extract of white beans reduces the amount of carbohydrates that break down and absorbed into the blood. Unfinished carbohydrates are excreted from the body, which leads to a decrease in the calorie content of the diet.

  • White beans extract: It can cause side effects, such as gas formation, bloating, diarrhea and discomfort in the abdomen.

• Fat blockers: These additives interfere with the absorption of fats in the intestines, contacting them and forming complexes that cannot be digested and absorbed. The most famous example is the chitosan obtained from crustacean shells. Chitosan is a dietary fiber that has the ability to bind fats.

  • Hitosan: It can cause side effects, such as constipation, nausea, vomiting, diarrhea and bloating. It can also reduce the absorption of fat -soluble vitamins (A, D, E, K).

• Suppliers of appetite: These additives affect hunger and saturation centers in the brain, reducing appetite and reducing food consumption. These include additives containing glucomannan (food fiber), 5-HTP (5-hydroxyrypthophanes) and Garzinia Extract of Cambodia.

  • Glucomanan: It is a soluble dietary fiber, which, when in contact with water, swells in the stomach, creating a feeling of satiety and reducing appetite. It is important to use glucomannan with a lot of water to avoid constipation and intestinal obstruction.
  • 5-HTP: It is the predecessor of serotonin, a neurotransmitter who plays a role in the regulation of mood, sleep and appetite. It is believed that 5-HTP can reduce appetite and craving for carbohydrates. Side effects can include nausea, vomiting, diarrhea, headaches and drowsiness. It is not recommended to take 5-HTP in combination with antidepressants.
  • Garcinia Extract of Cambodia (HCA): Contains hydroxilimonic acid (HCA), which is believed to inhibits an enzyme involved in the synthesis of fatty acids and increases serotonin levels. However, HCA effectiveness studies are contradictory. Possible side effects: nausea, stomach disorders, headaches.

• Diuretics (diuretics): These additives increase fluid elimination from the body, which leads to a temporary reduction in weight due to a decrease in the amount of water in the body. It is not recommended to use diuretics for weight loss, as they can lead to dehydration, electrolyte disorders and other serious health problems.

  • Herbal diuretics (for example, dandelion extract, parsley): We can cause dehydration, electrolyte disorders (potassium deficiency, sodium) and other health problems.

• Bades affecting the hormonal background: Some dietary supplements declare their ability to influence hormonal background, for example, regulate the level of insulin or thyroid hormones. However, such statements often do not have sufficient scientific evidence and can be dangerous to health.

  • Hormonal background violation: The use of such dietary supplements without a doctor’s control can lead to serious disorders in the work of the endocrine system.

2. Detailed analysis of popular ingredients used in dietary supplements for weight loss:

In addition to the above ingredients, there are other popular components often used in dietary supplements for weight loss. Consider them in more detail:

• L-Carnitin: An amino acid that plays a role in the transport of fatty acids in mitochondria, where they are oxidized for energy. It is believed that L-carnitine helps to burn fat and increase endurance. However, studies of the effectiveness of L-carnitine for weight loss are contradictory. Possible side effects: nausea, vomiting, stomach disorders.
• CLA (conjugated linoleic acid): A group of isomers of linoleic acid, which is believed to help burning fat, increase muscle mass and reduce cholesterol. However, CLA efficiency studies are contradictory. Possible side effects: stomach disorders, diarrhea, nausea.
• Chromium: A trace element that plays a role in the regulation of blood sugar and carbohydrate metabolism. It is believed that chrome can reduce craving for sweets and improve appetite control. However, studies of the effectiveness of chromium for weight loss are contradictory. Possible side effects: headaches, stomach disorders.
• Apple vinegar: It is believed that apple cider vinegar can reduce appetite, improve digestion and regulate blood sugar. However, scientific evidence of these statements is limited. The use of apple cider vinegar in an undiluted form can damage the enamel of the teeth and cause irritation of the esophagus.
• Food fibers (fiber): Soluble and insoluble dietary fibers contribute to saturation, slows down sugar and fats, improve digestion and regulate cholesterol. It is important to use a sufficient amount of fiber with food to maintain the health of the digestive system.

3. Legal aspects and regulation of dietary supplements for weight loss:

It is important to understand that dietary supplements are not drugs and do not pass strict clinical trials as medicines. In most countries, the regulation of dietary supplements is less strict than the regulation of drugs. This means that dietary supplement manufacturers are not required to prove the effectiveness and safety of their products before selling them.

Marking of dietary supplements should contain information about the composition, method of application, contraindications and possible side effects. However, often the information on the labels is incomplete or inaccurate.

When choosing dietary supplements for weight loss, it is necessary to be careful and prefer products from well -known and reliable manufacturers. It is important to study the composition of the product, read consumer reviews and consult a doctor or nutritionist.

II. Analysis of consumer reviews about dietary supplements for weight loss:

1. General trend in reviews: positive, negative, neutral.

Consumer reviews about dietary supplements for weight loss are extremely diverse and contradictory. In general, the following trends can be distinguished:

• Positive reviews: Often associated with a temporary weight loss, improvement of mood, energy increase and a decrease in appetite. However, it is important to take into account that these effects can be due not only to the action of dietary supplements, but also by other factors, such as a change in lifestyle, diet and physical exercises.
• Negative reviews: Often associated with the lack of effect, the development of side effects, disappointment and deceived expectations. Many consumers complain that dietary supplements did not help them lose weight, despite the diet and playing sports. Some note the development of serious side effects requiring medical care.
• Neutral reviews: Often they contain information that dietary supplements did not have a significant impact on weight, but did not cause serious side effects. Some consumers note that dietary supplements helped them slightly reduce their appetite or improve digestion, but did not lead to a significant weight loss.

It is important to consider that consumer reviews are subjective and cannot serve as reliable evidence of the effectiveness or safety of dietary supplements. The effectiveness of dietary supplements can depend on the individual characteristics of the body, lifestyle, diet and other factors.

IV. Alternative methods of weight loss: scientifically sound approaches.

1. Proper nutrition: the principles of a balanced diet.

Proper nutrition is the basis of a healthy weight loss. A balanced diet should include all the necessary nutrients in sufficient quantities, but with a limitation of calorie content. The basic principles of a balanced diet:

• Calorie control: To reduce weight, it is necessary to create a calorie deficit, that is, consume less calories than consumed. It is recommended to reduce the calorie content of the diet by 500-750 calories per day.
• Sufficient amount of protein: Protein plays an important role in maintaining muscle mass and creating a feeling of satiety. It is recommended to consume 1.2-1.5 grams of protein per kilogram of body weight per day.
• Fat consumption restriction: Limit the consumption of saturated and trans fats contained in fatty meat, dairy products, fried foods and processed products. Give preference to useful fats contained in fish, avocados, nuts and vegetable oils.
• Increase in fiber consumption: Fiber is found in vegetables, fruits, whole grain products and legumes. It promotes saturation, improves digestion and regulates blood sugar.
• Limiting the consumption of simple carbohydrates: Limit the consumption of sugar, sweets, white bread, pasta and other products containing simple carbohydrates. Give preference to complex carbohydrates contained in whole grain products, vegetables and fruits.
• Sufficient amount of water: Drink enough water during the day (at least 2 liters). Water promotes saturation, improves metabolism and helps to remove toxins from the body.
• Regular nutrition: Eat regularly, in small portions, 5-6 times a day. This will help maintain a stable blood sugar and control appetite.
• Avoid processed products: Recycled products often contain a lot of sugar, fat and salt, as well as few nutrients.
• Prepare food at home: When preparing food at home, you can control the ingredients and calorie content of dishes.

2. Regular physical activity: types of training and their effectiveness.

Regular physical activity is an important component of a healthy weight loss. Physical exercises help to burn calories, strengthen muscles, improve metabolism and increase endurance.

Types of training and their effectiveness:

• Cardio-training: Cardio training (running, swimming, cycling, walking) help to burn calories and improve the cardiovascular system. To reduce weight, it is recommended to engage in cardio training at least 150 minutes a week of moderate intensity or 75 minutes a week of high intensity.
• Power training: Power training (weight lifting, exercises with its own weight) help to strengthen muscles and accelerate metabolism. The more muscles you have, the more calories you burn at rest. It is recommended to engage in strength training at least 2 times a week.
• Interval training: Interval training (alternating periods of high and low intensity) help to burn more calories in a short period of time.
• Yoga and Pilates: Yoga and Pilates help improve flexibility, balance, coordination and strengthen the muscles of the cortex.
• Walking: Walking is a simple and affordable form of physical activity, which is suitable for people of any age and level of training.

3. Change in lifestyle: sleep, stress, bad habits.

A change in lifestyle plays an important role in the long -term success of weight loss. It is important to pay attention to sleep, stress and bad habits.

• Dream: The lack of sleep can lead to an increase in appetite, a decrease in metabolism and a deterioration in mood. Try to sleep at least 7-8 hours a day.
• Stress: Stress can lead to overeating and weight gain. Find healthy ways to cope with stress, such as meditation, yoga, walking in the fresh air or communication with friends and family.
• Bad habits: Refuse smoking and alcohol abuse. Smoking can lead to a decrease in appetite and weight loss, but this is an unhealthy way of losing weight. Alcohol contains a lot of calories and can reduce motivation for a healthy lifestyle.

4. Psychological aspects of losing weight: motivation, self -esteem, support.

Psychological aspects play an important role in the process of losing weight. It is important to have clear motivation, maintain high self -esteem and receive support from others.

• Motivation: Determine your goals to reduce weight and write them down. Regularly remind yourself of your goals and reasons why you want to lose weight.
• Self -assessment: Do not allow excess weight to influence your self -esteem. Appreciate yourself for your virtues and achievements.
• Support: Get support from friends, family, colleagues or specialists. Join the support group or find a weight loss partner.
• Positive thinking: Focus on the positive changes that occur in your life due to weight loss. Do not scold yourself for mistakes and failures.
• Contact the psychologist: If you have problems with food behavior, low self -esteem or depression, contact a psychologist.

V. Conclusion: an individual approach and a conscious choice.

The choice of the method of weight loss is an individual process that requires a conscious approach and accounting for the characteristics of the body. Dietary dietary supplements are not panacea and can be effective only in combination with proper nutrition, regular physical exertion and a change in lifestyle. Before taking dietary supplements, it is necessary to consult a doctor or nutritionist and carefully study the composition of the product and possible side effects. Alternative methods of weight loss, such as proper nutrition, physical activity, change in lifestyle and psychological support, are safer and more effective in the long -term perspective. The main thing is to find your individual path to a healthy weight and good health.
