Intermittent Fasting And Bulletproof Coffee: What You Should Know

Bulletproof Coffee Intermittent Fasting

The questions on how to combine intermittent fasting with different food types, like bulletproof coffee is very popular. Over the past few years, intermittent fasting has gained enormous popularity due to its incredible weight loss effects. And coming up with a diet that doesn’t eliminate any food or macronutrient from your table is quite refreshing.

Intermittent fasting is as simple as it gets. You can eat during a certain time window and then fast for the rest of the day. The most common patterns of fasting include the 16:8 and the 12:12.

You fast for 12 or 16 hours and eat whatever you want during those remaining 12 or 8 hours, respectively.

The only vague part about this diet is what you’re allowed to eat or drink during the fasting period. Of course, everyone knows that you can drink as much water as you want during fasting. In fact, nutritionists and physicians encourage you to do so.

However, other food elements have posed a controversy among healthcare professionals. In this article, we will discuss what Bulletproof coffee is and whether you can drink it during the fasting period of your intermittent fasting.

Bulletproof coffee

Bulletproof coffee is a special type of a calorie-loaded drink. It was invented to replace breakfast to not feel hungry, tired and distracted even if you skip the meal.

Here are the ingredients to make bulletproof coffee:

  • Coffee
  • Grass-fed
  • Unsalted butter
  • MCT oil

The CEO of the Bulletproof diet, Dave Asprey, promoted this coffee originally. Since then, it gained massive popularity. It hypes especially among individuals following the ketogenic diet and low-carb, high-fat diet.

Many people swear by the efficacy of this coffee and how it helped them increase their energy levels. They feel better and prolong their longevity. Others disagree with these statements and believe that regular consumption of this coffee could potentially harm your body.

The major three arguments against the bulletproof coffee are:

  • Elevated cholesterol levels
  • Elevated saturated fatty acids
  • Low nutrients

But this coffee is a great option for people in ketosis and other low carb diets.

Now we are familiar with the basics. Let us further discuss whether this coffee could break your fasting during intermittent fasting.

Does bulletproof coffee break down your intermittent fasting?

Many people believe that since the bulletproof coffee does not contain sugar, it will not break intermittent fasting; however, if you dig into a textbook of biochemistry, you will realize this statement is false.

The basic principle of intermittent fasting is to burn fat in your adipose tissues during the fasting period.

If you drink the bulletproof coffee during fasting, your body will switch from using endogenous fatty acids to converting triglycerides in the coffee to ketone bodies, thus eliminating the whole purpose of following the intermittent fasting diet.


Even though the intermittent fasting has great health benefits supported by scientific publications, it is primordial to avoid breaking your fasting to reap those benefits.

The bulletproof coffee offers multiple positive effects to our health; however, it might not be the best option for the intermitting fasting diet, especially during the fasting period.

In the perspective of ketosis, this coffee is definitely an option as it doesn’t break the state of ketosis.
