Introduction

Modern people are increasingly focused on health, consuming calories while trying to eliminate them - it's like having a cup of black coffee in one hand and a hamburger in the other. Many believe that drinking black coffee helps with weight loss because it only contains 5 calories, and the caffeine stimulates the heart, increasing basal metabolic rate. Is this really true?

What is Black Coffee?

Black coffee refers to pure coffee formed by grinding coffee beans into powder and releasing flavor substances in water at appropriate temperatures. The production process does not add any auxiliary ingredients (such as milk, sugar, etc.). In daily life, common black coffees include Americano, pour-over coffee, ice drip coffee, and cold brew coffee.

Can Simply Drinking Black Coffee Really Help with Weight Loss?

Caffeine does indeed stimulate the central nervous system and accelerate heart rate, which also increases basal metabolism. However! Yes, there's a however! The effect of caffeine on increasing basal metabolism is very small! Let's take an "example": an Americano containing 28g of espresso has 64mg of caffeine; a 227ml instant black coffee contains 62mg of caffeine; a 227ml pour-over coffee contains 32.4mg of caffeine. Black coffee with less than 100mg of caffeine content can only increase basal metabolism by 1-2%. Taking a woman with a basal metabolism of 1000 calories as an example, a 1-2% increase only adds a maximum of 20 calories to energy expenditure.

Debunking Black Coffee Myths!

Q: Can you lose weight by drinking black coffee for a month?
A: No, it needs to be combined with a reasonable diet and proper exercise during the period.

Q: Does black coffee have diuretic effects, so it can help with weight loss?
A: No, diuresis eliminates water, not fat. (Don't fool yourself, exercise properly!)

Q: Can drinking black coffee help with digestion?
A: Caffeine stimulates the central nervous system, stimulates gastrointestinal metabolism, enhances gastric motility, and reduces bloating. Therefore, you can appropriately drink a cup of black coffee after meals to help with digestion.

How to Quickly Make Black Coffee at Home/Office?

FrontStreet Coffee's drip coffee bags are a great choice! Drip coffee bags are a super simplified version of pour-over coffee. The structure is a coffee filter bag with "ears" containing a predetermined amount of pre-ground coffee powder. It eliminates the tedious steps of grinding coffee powder, preparing filter paper and dripper in pour-over coffee. You only need hot water and a cup to make authentic black coffee.

The method for brewing drip coffee is also very simple: first, prepare hot water, boil it and let it cool for one minute. Second, open the outer packaging and inner packaging sealing strip according to the instructions on the drip coffee packaging. Hang the two ears of the drip coffee bag on the cup. For the first pour, inject a small amount of water just to moisten the surface. Wait for the coffee powder to sink slightly, then inject the second amount of water until the bag is about 8/10 full. Then let the coffee liquid filter slowly, repeat the second pour to 8/10 full, and finally wait for all the coffee liquid to filter before enjoying.

Want to Brew Drip Coffee with a Sense of Ceremony?

No problem! The equipment you need to prepare includes a thermometer, timer, electronic scale, and pour-over kettle. FrontStreet Coffee's drip coffee bags have a net content of 10g, and the recommended brewing ratio is 1:15, so one drip coffee bag can brew 150g of coffee liquid; the recommended brewing water temperature is 90°C.

First, open the outer packaging and inner packaging of the drip coffee according to the instructions, and hang the drip coffee bag on a sharing pot or mug.

For the first pour, inject 20g of 90°C hot water, ensuring it covers the coffee powder, and let it bloom for 20-40 seconds. After this brief blooming period, the coffee powder has released a very rich aroma.

For the second and third pours, inject 65g of water respectively - the second pour brings the total water amount to 85g, and the third pour brings it to 150g. The brewing ratio can be adjusted according to personal taste. If you prefer a richer flavor, you can reduce the water; if you prefer a less intense flavor, you can increase the water. The total extraction time is 1 minute and 40 seconds. Finally, remove the drip coffee bag to complete the brewing and enjoy.
