Fat burners are such preparations that contain major components assisting the process of fat loss such as L-carnitine, ephedrine, caffeine and guarana extract. All fat burners can be divided into 2 groups: thermogenics and lipotropics.
Thermogenic effect is based on body temperature increase (on the average in 0.5-2.0 °C) that leads to the situation when our organism requires additional calories and gets them with the help of decomposition of its own fats. The biggest advantage of these preparations is that their base is constituted by different plant extracts. It’s also worth mentioning that thermogenics also increase our endurance.
Thermogenics block fat synthesis in the liver and increase decomposition of fatty tissues into fatty acids.
The maximum fat burning effect takes place if a preparation combines both thermogenics and lipotropics. Some people, when taking fat burners, are afraid that they can lead to decrease of muscle cells as well. But you shouldn’t be afraid: your protein molecules are safe. All you need to do is to assure enough protein to come to your organism (approximately 3rg per 1kg of body weight).
