What is Keto Coffee Aka Bulletproof Coffee With Butter?

From crossfit gyms to paleo diet cookbooks, keto coffee is one of the hottest trends in the health and fitness industry. But what is keto coffee? In this article, we’ll explain what keto coffee is, where it originated, the health benefits and how to make your own at home.

Key Takeaways

  • Keto coffee is a high-fat, low-carb beverage designed for those following a keto diet.
  • It contains healthy fats like grass-fed butter and MCT oil, which promote fat burning and weight loss by inducing ketosis – a metabolic state where your body burns fat for fuel instead of carbs.
  • Bulletproof coffee provides sustained energy throughout the day without the crash associated with regular caffeine consumption and can help improve focus and mental clarity.
  • By including it in your routine, you can enjoy decreased cravings and increased satiety, making it easier to stick to your dietary goals.
  • It is also called butter coffee or bulletproof coffee.

What is Keto Coffee?

Keto coffee, also known as bulletproof coffee, is a type of coffee that is combined with healthy fats to give it an extra boost of energy and nutrition. The basic recipe involves blending coffee with an amount of butter (unsalted grass-fed is the most popular chocie) or ghee and a medium-chain triglyceride (MCT) oil, typically derived from coconut oil. This combination of fats and fatty acids helps to promote a state of ketosis in the body, where it relies on fat for energy instead of carbohydrates.

You may think that people who put butter in coffee are crazy. They are usually following a low-carb, high-fat diet that aims to put the body into ketosis. The idea behind consuming butter in coffee is that the added fats provide sustained energy, increased mental clarity, and reduced hunger cravings. It is often used as a meal replacement or as a way to extend the fasting period during intermittent fasting.

The term “bulletproof coffee” was popularized by Dave Asprey, the creator of the Bulletproof Diet. It has gained popularity in the health and fitness community as a way to support a diet with low net carbs, and to optimize energy levels throughout the day. The Bulletproof brand also makes and markets their own MTC oil called “octane oil”.

Ingredients and Preparation of a Classic Bulletproof Coffee Recipe

The original bulletproof coffee recipe contains just 3 ingredients: 

  • Hot coffee, espresso or cold brew
  • Unsalted grass-fed butter or ghee
  • MCT oil

To prepare this energizing drink, simply brew your favorite cup of black coffee or cold brew, add a tablespoon of grass-fed butter and a tablespoon of MCT oil, and blend in a blender until frothy. 

Pro tip: You can also use a milk frother to make bulletproof coffee if you don’t have a blender.

A blender helps to properly mix the oil, butter and coffee

Difference between regular coffee and keto coffee

Regular coffee and keto coffee may look similar, but they are quite different in terms of their composition and effects on the body. Regular coffee is typically brewed with just water and ground coffee beans. You can also add milk, creamer and sweeteners for taste, or opt for something like a latte or cappuccino.

However, the classic keto coffee recipe is different. The addition of butter and MCT oil make a cup of keto coffee quite different from a regular cup of joe.

Benefits of Keto Coffee

A cup of bulletproof coffee offers several benefits. These include:

  • Fat burning and weight loss
  • An immediate energy boost
  • Increased focus 
  • May help you feel less hungry

The fats used in the different keto coffee drinks are believed to support ketosis – a metabolic state where your body burns fat for fuel instead of carbohydrates.

By including these fats in the brewed coffee, you can increase satietycontrol cravings, and promote a greater calorie burn throughout the day. Bulletproof coffee is particularly appealing to low-carb and keto dieters as it aligns with their macronutrient goals and can help accelerate their weight loss journey.

The medium-chain triglycerides in the MCT oil are rapidly absorbed by the body and converted into ketones – a type of fuel that your brain loves. Grass-fed butter is another key ingredient that adds richness and creaminess to the mouthfeel.

So if you’re looking to shed pounds while still enjoying your daily dose of caffeine, consider making keto coffee to see if you like it.

Consume In Moderation

In conclusion, putting butter in coffee is a good keto option for those looking for a high-fat coffee beverage. It combines healthier fats like MCT oil and grass fed butter to promote fat burning, to sustain energy, and to increase focus.

It is one of the best coffee drinks for those following a low carbohydrate lifestyle and can be a delicious way to support weight loss goals while still enjoying a morning pick-me-up.
