Thermogenesis Fat Burner

Most fat burners make use of the principle of thermogenesis. Caffeine-containing substances such as natural caffeine, green tea extract or guarana specifically stimulate the metabolism. As a result, the pulse and blood pressure rise, an increased release of adrenaline and an increase in body temperature occurs. This process stimulates the burning of fat cells. The same effect can be achieved with spices such as cayenne pepper and the capsaicin contained in peperonis. So is it enough to sit on the couch and eat a bag of chips while the fat burners melt the fat? I’m afraid not. The effect of the fat burners in normal dosage alone is too small to cause a noticeable and lasting reduction of body fat. However, the preparations can also be used to support weight reduction. In endurance and weight training, they can possibly intensify the effect of fat burning. The prerequisite for this is that the user has a balanced and healthy diet while taking the product. However, the products are not completely unproblematic due to their usually very high caffeine content. This is especially true if they are taken in combination with other caffeine-containing drinks such as energy drinks, cola, coffee or tea and with increased physical activity. The maximum recommended daily dose of caffeine for a healthy adult is 400 milligrams. Some fat burners reach or exceed this dose alone. A higher dose of caffeine can cause tachycardia, sweating, arrhythmia, insomnia and digestive problems.

A further variant are the so-called thyroid regulators. These products work in principle like thermogenesis fat burners, but make the detour via the thyroid gland. Various substances cause the thyroid gland to secrete hormones. The hormones T3 and T4 have a stimulating effect on the metabolism. As a result – as with thermogenesis – body temperature increases and fat burning increases. However, here too sport and a balanced, low-calorie diet are indispensable to achieve visible results. The disadvantage is that many products in this category contain very high doses of iodine. The German Nutrition Society (DGE) recommends not to exceed the maximum value of 500 µg iodine per day. Overdosage with iodine can cause side effects such as tachycardia, intestinal problems and skin rashes.

Some forms of appetite suppressants are considered problematic, which should also be added to the category of fat burners. With substances such as green coffee beans, guarana or caffeine, they cause a reduced appetite, which is supposed to lead to a lower food intake and consequently to a weight reduction. In other cases, substances that swell in the stomach, such as konjac root, are supposed to provide a feeling of satiety. Products with chitosan are also popular. This is supposed to bind fat from food and excrete it directly from the body. Similar preparations are available for binding carbohydrates from food. Studies have so far not shown any particular efficacy, at least in the case of chitosan.

Caution is advised with products containing the alkaloid synephrine. The Federal Institute for Risk Assessment (BfR) recently warned that fat burners with synephrine greatly increase the risk of sudden severe blood pressure crises and heart attacks. The problem: Synephrine and caffeine are often offered in combination. However, both substances can reinforce each other in their effect. According to BfR, the maximum daily dose should not exceed 6.7 mg synephrine. However, this dose is already reached when eating some mandarins or some glasses of orange juice.

Anyone who decides to take a fat burner should first make sure that the product comes from the EU and is also manufactured in the EU. This gives a certain assurance that the product does not contain any substances banned in Germany. The intake should always be according to the manufacturer’s instructions. In any case, it is advisable to consult your family doctor briefly before use. Because some preparations can have a considerable influence on regularly taken medications such as the pill or blood pressure medications. Pregnant women, the elderly and people with cardiovascular problems should refrain from taking it. Especially for preparations with a high dose of caffeine the application is strongly advised against. But the products are also ineffective for other users without a healthy and calorie-reduced diet and increased exercise.
