Most fat burners sold are based on two to three biologically active substances. Here are the main components that are most often included in these blends.
Ephedrine and its natural sources
This is a natural alkaloid from the ephedra herb family, which is also obtained synthetically. It has strong lipolytic and ergogenic effects. Natural l-ephedrine is the most active; synthetic (dl-) has about half of its activity. Ephedrine stimulates fat burning by several mechanisms at once. This may be due to the so-called “reverse dependence” – an increase in the thermogenic effect with prolonged use (the ergogenic effect of ephedrine is addictive, although it is used, for example, by soccer players).
Ma-huang is the Chinese name for ephedra. It also contains other biologically active substances that enhance its lipolytic effect. Ephedrine has been used as an ergogenic agent for over 3,000 years!!!, and during that time, its effectiveness and relatively low toxicity have been proven. However, there are contraindications to its use – such as high blood pressure, cardiovascular disease, and individual intolerance. Before you start taking it, consult your doctor!
Sometimes, however, you have to stop taking it. Because of the addictive and side effects, it is better to alternate it with other drugs, arranging a short course of 1-2 weeks or intermittent reception (every other day or two, not more than a month in a row).
Caffeine
A natural purine base found in tea, coffee, cocoa, kola nuts and some herbs (guarana). According to studies, caffeine helps to speed up the metabolism and therefore burn fat faster. However, it is relatively weak on its own: you need about 600 mg of caffeine per day to get noticeable results. Such an amount can negatively affect heart function and cause a number of other side effects.
Drinking caffeine-containing drinks at home is addictive, resulting in reduced thermogenic effects and increased side effects. With interrupted intake, withdrawal syndrome is also noted. If you regularly drink strong tea or coffee, do it better in the morning or in the afternoon, no more than 1-2 cups a day.
Hydroxylimonic acid.
It is found in a number of fruits, especially in the fruit of the Indian garcinia cambogia tree. This substance is not a thermogenic agent, but interferes with triglyceride synthesis in the liver by blocking the enzyme citrate lyase. Including hydroxylimonic acid in the daily diet helps to slow down the processes leading to fat accumulation. When citrate lyase activity is reduced, plasma glucose levels remain elevated and appetite is suppressed.
Hydroxylimonic acid can also increase glycogen levels in the liver. Recently, there have been reports that this substance itself allegedly has almost no thermogenic effect, but their credibility is questionable. The fact is that such rumours are based on unverified laboratory experimental data and, most probably, are inspired by those who want to “crush” successfully marketed products of competitors.
Increased dosages are not accompanied by any unpleasant phenomena. If they do occur, it is usually sufficient to lower the dose. Little is known about the side effects of this drug. Obviously, there are no life-threatening reactions. Individual intolerance or allergies are possible.
