Guide reading

People in modern society pay more and more attention to their health, eating calories while trying to reduce them, which is a cup of black coffee in the left hand and a hamburger in the right hand. Many people think that drinking black coffee can lose weight and reduce fat because black coffee has only 5 calories, and the caffeine in it has an exciting effect, which can speed up the heartbeat and increase the basal metabolic rate. Is this really the case?

What is black coffee?

Caffeine and black coffee refer to the pure coffee formed by releasing flavor substances in the water at the right temperature after the coffee beans are ground into powder without adding any accessories (such as milk, sugar, etc.) in the production process. The common black coffee in our life are American coffee, hand-brewed coffee, iced coffee and cold coffee.

Can you really lose weight by simply drinking black coffee?

Caffeine does excite the central nervous system, accelerate the heartbeat, and improve basic metabolism. But! Yes, there are buts! The effect of caffeine on improving basic metabolism is very small! Let's take a "chestnut": a cup of American coffee with 28g espresso contains 64mg caffeine; a cup of 227ml instant black coffee contains 62mg caffeine; a cup of 227ml hand coffee contains 32.4mg. These black coffees, which contain less caffeine than 100mg, can only increase basic metabolism by 1-2%. Take girls with a basic metabolism of 1000 calories as an example, an increase of 1-2 per cent only increases energy consumption by 20 calories at most.

How to make black coffee quickly at home / office?

Hanging earbags in front of the street is a good choice! The hanging-ear coffee bag is a super simple version of hand-brewed coffee. The structure is a coffee filter bag with "ears" containing a certain amount of pre-ground coffee powder. Instead of tedious operations such as grinding coffee powder and preparing filter paper filter cups in hand brewing coffee, only hot water and cups are needed to make authentic black coffee.

The method of brewing hanging-ear coffee is also very simple: first, prepare hot water, boil and cool for a minute, and then tear open the outer package and the sealing strip of the inner package according to the label of the hanging-ear coffee package. Put the two ear racks of the coffee on the quilt. A small amount of water is injected into the first section to moisten the surface. Wait for the coffee powder to sink slightly, then inject the second section of water until the earbag is nearly 8 minutes full, then let the coffee liquid slowly filter, repeat the second paragraph of water until the earbag is 8 minutes full, and finally wait for the coffee liquid to be fully filtered.

In the first stage, pour 20 grams of hot water at 90 degrees Celsius to make sure there is no coffee powder and steam for 20 to 40 seconds. After a short stew, the coffee powder has released a very strong aroma.
