Fat Burner supplements are great to use whenever your body is going to be burning more calories such as during exercise because the ingredients in this type of weight loss product help your body to be able to burn more fat as a fuel source. Thermogenic products, on the other hand, contain ingredients that actually cause your metabolism and fat burning to increase through the process of thermogenesis which is a similar effect in terms of fat burning as is achieved from exercising. Therefore, a great time to take a Fat Burner type product is whenever you also plan to use a Thermogenic so that you will achieve a synergistic effect that will help you to burn as much fat as possible. Using several supplements together like this is commonly known as stacking and is done to produce a greater combined effect than either supplement will produce when taken alone. Of course an even better strategy is to take this combination just before some exercise to push your fat burning to the max for faster weight loss. And if you are really serious about pushing your body fat down as low as possible then use this combination of supplements along with some intense weight training and you will be able to attain the kind of low body fat percentage usually only seen in professional athletes. Using supplements like these together that increase fat burning is one of the tricks that athletes have been using for years so now that you know about this trick you can use it to drastically lower your own body fat to a level that will make even athletes ask you for your secret.
