Bulletproof coffee is being consumed by hundreds of people in the world, especially those who want to fast, and they can not have anything but coffee, and they get hungry in the morning. If you are one of them, then maybe it's time to try this coffee.
This recipe, although based on the original recipe , contains some additions that make the coffee more delicious and beneficial for the body while is the best choice for those who follow a low carbohydrate diet.
Note that although intermittent fasting has positive results, it is not suggested for those who have thyroid problems or those who have tried many diets in the past and their body is still exhausted. So a properly prepared breakfast or this coffee can be a better choice.
What is Bulletproof Coffee?
Bulletproof coffee, is an "upgraded" coffee that contains only fat (and sometimes protein), which helps the body and the brain. For example, Medium chain triglycerides (MCTs), found in coconut oil, one of its key ingredients, helps increase metabolism by as much as 25% .
The basic recipe for Bulletproof Coffee
Bulletproof coffee is very easy to make.
- 2-2½ teaspoons of coffee, if you use powder coffee. Otherwise a dose of coffee, hot
- 1-2 teaspoons of coconut oil
- 1-2 teaspoons unsalted butter or ghee (ghee is the butter cooked without its fat)
If you use coffee powder, boil water and put the coffee in the mug. Add the coconut oil and butter and pour the water.
If you use coffee from machine, put the coffee into a cup. Then add coconut oil and butter.
Mix well with a strong mixer (you can use and a hand-held mixer), because the butter must be well mixed. You will see a foam above the coffee. This coffee is very tasty and can keep you satisfied with absolutely no cravings for hours.
The extra recipe of the Bulletproof coffee
This coffee is even better than the classic Bulletproof coffee.
- 2-2½ teaspoons of coffee, if you use powder coffee. Otherwise a dose of coffee, hot.
- 1-2 teaspoons of coconut oil or MTC oil or coconut milk (full fat, unsweetened)
- 1-2 teaspoons unsalted butter or ghee (the butter cooked without its fat)
- 1 teaspoon of unsweetened cocoa powder
- 1 teaspoon whey protein of your choice (optional)
- ½-1 teaspoon calorie and sugar free sweetener (optional)
- 1/8 of the spoonful of Himalayan salt
- A pinch of black pepper (1/16 of a teaspoon) (optional)
The reason Himalayan salt has been added (less flavor than classic salt) is because sodium, one of the main electrolytes, is very easily lost on low carb diets due to lower insulin levels . This is why those who follow such diets suffer from headaches, tiredness, cramps and constipation.
Black pepper added because it can boost the metabolism. 
Unsweetened cocoa has the advantage of being low in calories. It also contains essential minerals that support your heart, bones and immune system.  Thus it's one of the most powerful antioxidants around.
Adding Whey protein in the mix can prevent muscle loss while not affecting insulin sensitivity or interfering much with your fat burning mode. Consuming protein increases free amino acid (FAA) levels, which stops the potential breakdown of muscle, and preserves lean tissue (a process called proteolysis). Just 10 grams of protein will do the trick. 
You will lose the benefits of autophagy (cellular cleaning) though if you add protein.  I usually break my 16hrs water fast with this coffee.
As above, pour all the ingredients into a cup. If you add Whey protein, you should add some cold water first to dissolve it. Then, mix all ingredients with the mixer.
Enjoy the best - at least on taste - coffee you've ever drank.
