Are you also looking for that "magic" solution to make your weight loss journey a success? We often hear that black coffee helps with weight loss, but is this true? If so, should we drink as much of it as needed to lose weight? The answer will delight you.

Yes, black coffee not only helps you lose sleep, but it also has the power to accelerate the fat-burning process in your body. It can boost your metabolism and make you fit, but wait... you'll only reap the benefits if you drink it in the right way and in the right quantity. Let's learn from dietitian Tamanna Dayal how this seemingly simple drink works on your body.
How does black coffee promote weight loss?
Chlorogenic acid is found in black coffee. This substance reduces glucose production, which accelerates fat burning in your body.
In addition, black coffee also works on our liver. It's a simple rule that anything that activates your liver automatically boosts your metabolism. Furthermore, it helps detoxify the body, giving a powerful boost to your weight loss journey.
Who should drink black coffee and when?
Black coffee isn't right for everyone. It's important to understand your body type before drinking it:
Those with acidity: If you suffer from acidity, you should avoid black coffee altogether.
Those with an alkaline body: If you have an alkaline body, you can consume it on an empty stomach in the morning. This will boost your energy levels, and you'll be able to perform workouts or any other physical activity more easily.
Take special care of your age and quantity.
Black coffee is beneficial, but too much of anything is bad.
Age Considerations: If you're over 45 and frequently drink 6-7 cups of black coffee throughout the day, it can increase your risk of high blood pressure.
Right Amount: Drinking 3-4 cups of black coffee a day is sufficient. This amount is considered good for increasing your fat metabolism.

Don't Make the Mistake of Drinking at Night
Many people think that drinking black coffee at night will burn fat while you sleep. However, this isn't the case. Drinking black coffee before bed will neither promote weight loss nor ensure a good night's sleep. Therefore, avoid drinking it before bed.
Drinking black coffee at the right time and in the right amount can definitely help you lose weight by increasing your metabolism and energy.
