Coffee for Intermittent Fasting

Butter coffee is a high-fat, low-carb drink that is essentially hot coffee blended with butter or another healthy fat such as coconut oil. Butter coffee generally has between 150-300 calories per serving, depending on how much fat you add.

The benefit of butter coffee is that it has no carbs or sugar. If you are practicing intermittent fasting or a ketogenic diet, then butter coffee is a way to help extend your fast without raising your blood sugar enough to break your fast.

It should be noted, however, that there are no long-term studies on the risks or benefits of drinking butter coffee. But, studies do seem to agree that moderate consumption of coffee imparts numerous health benefits.

Coffee can also help with weight loss! See my whole article about the best coffee for weight loss.

Butter coffee promises to provide sustained energy and increased mental clarity due to the caffeine and medium chain triglycerides from the butter.

Butter Coffee Recipe Steps

Step One: Start With Cold Press or Brewed Coffee

To make this recipe for butter coffee, start with two cups of cold brew organic coffee or regular brewed black coffee (see my list of the best organic coffee brands).

If you start with cold brew coffee, you’ll need to heat the coffee before you blend it with the butter.

Step Two: Combine the Coffee & Butter in a High-Speed Blender

Next, combine your hot coffee with 1-2 tablespoons of grass-fed butter in a high-speed blender like a Blendtec or a Vitamix.

You can use a regular blender or a battery-powered whisker, but you’ll get the optimal froth in your butter coffee by using a high-speed blender.

Step Three: Add MCT Oil or Coconut Oil

Before you blend your butter coffee, you can also add ingredients including MCT oil (you can use coconut oil if you prefer) for medium-chain triglycerides and some unflavored collagen protein powder.

Quite honestly, I think the MCT oil is optional with your cup of coffee if you’re going to eat breakfast, but MCT oil in coffee may help increase blood ketone levels if you’re fasting. Caffeine in coffee plus MCT oil also increases ketone bodies.

The collagen peptides are also optional, and may break your fast due to the protein content (learn more about collagen protein). But, adding protein to your keto butter coffee is a great option for women or anyone who needs more protein early in the day (see my Protein Coffee recipe).

Other nutritious optional add-ins ingredients you can include your butter coffee include an egg yolk, cacao nibs, or ground cinnamon. Try to avoid artificial sweeteners or added sugars (see my list of the best natural sugar substitutes).

Step Four: Blend and Enjoy!

The final step for this butter coffee recipe is to blend it all together for about 10-15 seconds, or until everything is combined and a froth has formed. Serve hot and enjoy!

Note: always be cautious when blending hot liquids. It’s a good idea to not overfill the blender and to put a towel over the top in case any of the liquid leaks out while blending. 

This recipe gets made fast! If you use cold-press coffee you’ve prepared the night before, you literally only need 5 minutes from start to finish (more like 2 minutes).

Potential Benefits of Butter Coffee

1. Nutrition

First off, using grass-fed butter provides a good source of conjugated linoleic acid (CLA), butyrate, vitamin A, and vitamin K. Butter also has healthy fatty acids including butyric acid.

Friends with dairy sensitivities can always use ghee, by the way. People on a vegan diet can use coconut butter or coconut oil.

My butter coffee recipe has approximately:

  • 150 calories
  • 11 grams of fat
  • 0 grams of carbohydrates
  • and 11 grams of protein (from the collagen)

Since butter coffee is full of healthy fats with no sugar, it can help with a sugar detox diet.

2. It makes you feel good

Another reason to try starting your day with butter coffee is because it can make you feel good mentally and physically.

If regular coffee is too strong for you, you can also use decaf coffee or black tea. If you are on a low-histamine diet, you can even use herbal tea to make your butter drink.

3. It assists with intermittent fasting

Lastly, butter coffee can displace or delay breakfast, allowing for intermittent fasting or aiding with nutritional ketosis.

But, before you try intermittent fasting, you should definitely check with your doctor first, especially if you are a pre-menopausal woman (learn more about the potential risks of fasting for women).

Recipe Tips & Substitutions

Recipe FAQs

Can I use a regular blender to make butter coffee?

Yes, absolutely! You will get the most amount of foam with a high-speed blender, but you can use a whisk, milk frother, or regular blender to make this keto coffee recipe.

What can I use if I’m dairy-free or vegan?

If you can’t tolerate dairy or don’t consume dairy for ethical reasons, you can use coconut milk or a sugar-free vegan coffee creamer instead of butter. Don’t use any heavy cream, but you can use almond milk instead.

Can I make an iced version of butter coffee?

Yes, but you’ll need to cool it down and serve it with ice. See my Iced Coffee Recipe.

Who invented butter coffee?

The recipe for butter coffee, or bulletproof coffee, is attributed to Dave Asprey who had yak butter tea on a trip and was inspired. For the Dave Asprey bulletproof coffee recipe, you should include both butter and brain octane oil (his branded version of MCT oil) and no sugar.

Dave is the creator of the bulletproof diet which aim to assist with weight loss and brain function while boosting cognitive function with a diet with high fat content and low in net carbs. He also places an emphasis on high-quality ingredients.

Should I use salted butter or unsalted butter when making butter coffee?

You can use either, but salted butter will have the best flavor.
