In addition to the caffeine, chlorogenic acid in a cup of black coffee will help the fat burning process. Those substances will activate the enzyme in the digestion system such as lipase which is able to break down fat. In the other word, lipase will helps the process to burn fat, since fat need to be broken down before it is perfectly burned. The normal process might take about 20 minutes to burn fat. However, the caffeine and chlorogenic acid in a cup of black coffee will make the process efficiently faster.
Taste the coffee black every time before adding cream or sugar- Before you add things to your coffee take a moment to taste it black. Don’t just take a sip, TASTE it. Think about what flavors you are getting out of your coffee and what you like and don’t like. If possible set a little black coffee to the side to taste again once it has cooled to room temperature. You will be surprised how much more pronounced the flavors are once the coffee has cooled a bit.
The water is normally kept at room temperature, but chilled water is also used. The grounds are filtered out of the water after they have been steeped using a paper coffee filter, a fine metal sieve, a French press, or felt, in the case of the "Toddy" brewing system. The result is a coffee concentrate that is diluted with water or milk, and is served hot, over ice, or blended with ice and other ingredients such as chocolate.
