Discover 5 suggestions for proven fat burners to give you the figure of your dreams
Overweight and obesity for many people is only a big aesthetic problem. However, it is worth remembering that excessive accumulation of fat tissue is primarily a health risk, for example in the form of diabetes, atherosclerosis or hypertension. A healthy diet and sport are the main factors in the fight against "fatness", but there are also supplements that are allies in maintaining a healthy weight. In this article, you will learn all about adipose tissue and the best supplements for effective weight loss.
Adipose tissue
Adipose tissue is part of the connective tissue, which is found primarily in the subcutaneous layer of the skin. It is predominantly made up of adipocytes - cells with the ability to store fat and nutrients. Its most important function is to insulate the body (insulating against cold, maintaining the correct temperature). It also protects the internal organs from injury and influences hormone management. Correct amounts of adipose tissue are needed for the body to function properly.
The appropriate level of adipose tissue in women is 20-25% of body weight, while in men it is 15-20%. Higher values are considered obesity, which is harmful to health and can lead to many serious diseases. The location of body fat depends on age, gender, lifestyle and genetics. In the case of women, it tends to accumulate around the hips, buttocks and thighs. Among men, fat is most often located around the abdomen, chest, neck and face.
Interestingly, adipocytes are already present in a 14-week-old foetus. At birth, adipose tissue accounts for approximately 13% of a newborn's body weight, and by the end of the first year of life, it already accounts for 28%. During adolescence, adipose tissue also increases in volume, but this is usually a fairly rapidly passing process. During the first years of life, adipose tissue mass increases mainly due to an increase in the size of adipocytes. Later, on the other hand, this process is caused by an increase in the number of fat cells.
Types of adipose tissue
In humans and other mammals, there are two types of adipose tissue:
- - white adipose tissue - also known as yellow tissue;
- - brown adipose tissue;
Brown adiposetissue is an important source of heat, especially in newborns and infants. During infancy it is mainly localised in the intercostal region, along the spine, in the neck and in the perirenal region. With age, this type of adipose tissue decreases in quantity. In adults, its function is not only to generate small amounts of heat, but also to prevent insulin resistance and maintain body weight.
Brown adipose tissue is characterised by a specific structure. It is characterised by numerous fat droplets with a single, round and centrally located cell nucleus. It owes its brown colour to the large number of mitochondria
Yellow adipose tissue accumulates under the skin and between the internal organs. Its excess is responsible for obesity. The main role of this type of adipose tissue is:
- - storing fatty acids for energy purposes;
- - protection of internal organs from injury and damage;
- - thermal insulation;
- - storage and production of certain hormones.
Adipose tissue in the adult influences the levels of hormones such as insulin and leptin. The accumulation of yellow adipose tissue depends on age, gender and, above all, lifestyle. Lack of physical activity, a sedentary lifestyle, inadequate diet and excess stress promote obesity, - the excessive accumulation of yellow adipose tissue.
Yellow adipose tissue cells contain a single, large fat droplet surrounded by a thin layer of cytoplasm and a single, laterally located cell nucleus.
How can fat tissue be got rid of?
The accumulation of large amounts of adipose tissue leads to overweight and obesity, which are harmful to health. The best way to get rid of body fat is through a healthy diet and physical activity.
It is important to remember that not only the quantity of food, but also its quality, is of great importance in reducing excess body fat. It is advisable to include plenty of citrus fruits in your diet, as they are a source of polyphenols that aid weight loss. Capsaicin, found in hot peppers, and phytosterols, found in legumes, also help burn fat.
It is important not to completely exclude fats from the diet, as this will result in harmful deficiencies.
An effective way to get rid of excess body fat is through physical activity and exercise. Brown adipose tissue can be stimulated by means of intensive and short exercises, so that calories are burned long after the workout is over.
Sport and diet can be supported by special weight loss preparations based on natural ingredients. These include, among others, the very popular dietary supplements - fat burners.
What are fat burners?
Fat burners are products designed to increase the rate at which body fat is shed. They are supplements in the form of capsules, tablets, powder to dissolve or liquids, e.g. in the form of teas supporting the weight loss process.
The effect of fat burners can be felt on several levels. The first is the thermogenic effect, which affects body heat. Thermogenesis is to use fat tissue for energy. It is a phenomenon that involves an increased ability to oxidise fatty acids. This process is influenced by ingredients such as caffeine, capsaicin from cayenne pepper, synephrine from bitter orange or tea catechins, among others.
The second level is the lipolytic action. This is the process of breaking down fat tissue into free fatty acids and glycerol. Our body cannot make direct use of fat stored as adipose tissue. The cells must release the stored fat, which is broken down into a form so that the cellular mitochondria create energy from it.
In addition, fat burners activate the nervous system, which improves mood and increases the desire for physical activity.
Fat burners are also responsible for suppressing appetite. This is achieved by increasing thermogenesis, which affects the feeling of satiety. Fat burners usually contain ingredients that affect tissue insulin sensitivity and regulate blood sugar levels. This causes cravings to be significantly reduced.
These fat burners, whose composition is primarily based on caffeine, catechin from green tea and capsaicin from black pepper, have a good reputation among medical professionals. It turns out that their single consumption can increase energy expenditure by up to 4% and regular consumption by up to 11%.
Types of fat burners
The fat burners that are available on the market are divided into thermogenics and lipotropic substances.
Fat burn ers inthe form of thermogenics contain stimulants in their composition, i.e. substances which, when ingested, activate the process of thermogenesis in the body, among other things increasing body temperature, energy levels, as well as blood flow in the veins. As a result, fat metabolism is accelerated, which in turn leads to faster fat burning. The results of taking thermogenics can be seen in a short time. However, it should be remembered that they are not suitable for people with cardiovascular or nervous system problems. For such people, natural fat burners without stimulants are recommended.
Fat burners, on the other hand, which are composed of lipotropic substances, are preparations which contribute to increasing the processes of lipolysis in the human body, i.e. the breakdown of fat cells and their elimination. They contain natural ingredients and are free of stimulants.
Fat burners - for whom?
Fat burners are designed for people who want to reduce excess body fat and improve their figure. They are very popular with people leading active lifestyles as they accelerate weight loss during training.
Also non-exercisers can reach for fat burners, which, together with a well-chosen diet, can contribute to the reduction of body fat, e.g. by raising body temperature.
Those who are new to supplementation should choose preparations with a weaker and more stable effect, e.g. those based on natural ingredients. Those with a longer training period and experience in taking fat burners, on the other hand, should use preparations combining natural ingredients with stimulants or synthetic substances. Achieving a greater stimulation will contribute to the effectiveness of exercise and thus the burning of excessive fat tissue.
Fat burners, despite their safety approvals, cannot be used by everyone. Some of the active ingredients in these products cause an increase in heart rate or blood pressure. For this reason, fat burners are not recommended for people with cardiovascular diseases - some ingredients, such as caffeine or guarana, increase the amount of catecholamines, which leads to an increase in blood pressure. Additionally, increased temperature and increased blood flow can exacerbate symptoms in people struggling with hypertension.
Some components of fat burners can affect the body's insulin and glucose metabolism. Combining these preparations with medication used by diabetics can result in metabolic disturbances.
Also, people with very high levels of body fat should not start the fight against obesity with fat burners. Initially, they should focus on choosing an appropriate diet and level of physical activity, and only start supplementation after some time.
It is extremely important to use fat burners with care and according to the recommendations. It is always advisable to consult a professional before starting any supplementation.
What are the effects of using fat burners?
The use of fat burners can produce a variety of results, but it is important to remember that these supplements should be in support of a healthy lifestyle, which includes a balanced diet and regular physical activity. The most common effects of fat burners are:
Accelerated metabolism: Fat burners can help increase your metabolic rate, which can contribute to burning more calories.
Increased energy: Some fat burners contain ingredients that can increase energy levels, which can help you perform your workouts more efficiently.
Improved focus: Some fat burners ingredients have stimulating properties that can improve focus and concentration.
Appetite reduction: Some fat burners contain ingredients that can help control appetite and reduce cravings.
It is worth noting that the effects of taking fat burners may vary depending on the individual body's needs and overall physical condition. Supplements should be used skilfully and it is always a good idea to consult a doctor or nutritionist before starting to take them. Excessive supplementation is not recommended and can be harmful to the body.
Key ingredients in fat burners
The most effective fat burners have stimulants in their formulation, as well as natural plant extracts. The most common ingredients in these formulations include:
- Caffeine - is a powerful stimulant that raises blood pressure and increases body heat. It effectively burns fat cells.
- L-carnitine - reduces fat tissue, using it as an energy source.
- Green tea - has catechins in its composition that inhibit fat absorption. Promotes fat reduction and speeds up metabolism.
- Yerba-Mate - stimulates metabolic processes in the body and contributes to fat reduction. It also regulates blood glucose levels.
- Guarana - thanks to the caffeine content of the seeds, it accelerates the burning of calories and stimulates the process of thermogenesis, thus supporting fat burning.
- Bitter orange - raises body temperature, leading to a boost in metabolism and accelerated blood flow.
- CLA (linoleic acid) - lowers blood glucose levels, increases energy expenditure and promotes fat cell death.
- Hot pepper extract - contains capsaicin, which accelerates circulation, dilates blood vessels, boosts metabolism and metabolism.
- Piperine - found in pepper increases thermogenic processes in the body, supports detoxification, contributes to getting rid of fat, improves digestion and metabolism.
Advantages of
A good fat burner should, above all, effectively support fat reduction. Other advantages of using these preparations include:
- Raising body temperature.
- Acceleration of blood flow.
- Conversion of fat into energy during physical activity.
- Removal of excess water from the body.
- Increasing energy levels and endurance.
- Reducing appetite.
Disadvantages
The use of fat burners can also come with some disadvantages. Examples include:
- Occurrence of side effects.
- Limited effectiveness.
- Lack of long-term studies on long-term use.
How often to use fat burners?
The frequency of dosage of fat burners depends on the specific product and the manufacturer's recommendations. In general, most fat burners are taken 1-3 times a day. Dosage may vary depending on the active ingredients and the form of the supplement.
When using fat burners together with training, the time of training is not irrelevant. For activities performed in the evenings, it is best to reach for a fat burner without stimulants such as caffeine to avoid sleep problems.
If training takes place in the morning, it is best to take the second dose of the fat burner by 4 pm. Fat burners work all the time and affect, among other things, the physiological reactions that are responsible for energy utilisation.
Some fat burners (in the form of weight-loss diets) are designed for a specific treatment period, usually about one month. After this time, it is necessary to take a break from taking them again.
It is important to strictly follow the recommendations on the product packaging or those given by a nutrition professional or doctor. Some fat burners contain ingredients that can affect the nervous system and heart rhythm, so it is important to avoid exceeding the recommended dosage.
