Why Bulletproof is My Favorite Coffee

Bulletproof Coffee (also known as butter coffee or fat coffee or high octane coffee) is my favorite coffee. It’s not only delicious, but there are a lot of health benefits to drinking Bulletproof Coffee as well.

If you’ve never heard of Bulletproof Coffee, don’t worry, I will explain it below.

I am a daily and long-time coffee drinker. I love how it smells, I love how it tastes, I love that warm feeling you get inside after the first sip. My current routine is to alternate Bulletproof Coffee with my second favorite coffee, Starbucks Pike Place Roast.

Drinking any coffee has short- and long-term effects on your brain. The short-term effect of coffee on mood may be due to altered serotonin and dopamine activity, whereas the mechanisms behind its potential long-term effects on mood may relate to its antioxidant and anti-inflammatory properties.

What is Bulletproof Coffee?

I learned about this coffee in the book The Bulletproof Diet by Dave Asprey. The book has a ton of great information about how to live a healthier life. Some of the best topics include how to get better sleep, what supplements to take, the best ways to cook your food, and the best foods to eat.

Before we get to the coffee, I should explain that it’s intended to be part of an intermittent fasting routine. If you are new to intermittent fasting, it means restricting eating to a shortened period each day, typically 6-8 hours, and fasting the remainder of the day. Intermittent fasting aids fat loss, prevents cancer, builds muscle and increases resilience.

While there are a lot of great benefits, intermittent fasting is HARD. Even though you generally eat the same number of calories in a day when intermittent fasting, you go a lot of hours without eating.

For example, when I do intermittent fasting, I eat an early dinner, sleep, and then skip breakfast the next day. This period without food can make for a hungry morning and cause energy to decline mid-workday.

The Bulletproof Diet offers an alternative to traditional intermittent fasting, called Bulletproof Intermittent Fasting. The idea is to drink Bulletproof Coffee in the morning while otherwise fasting. The coffee includes fats and oils to keep you full.

Because this coffee does not include protein, carbs, or sugar, your body stays in fasting mode while the drink satisfies your hunger.

Bulletproof Coffee Recipe

First, it is recommended that you use a mesh filter or french press to make the coffee. You can use any coffee, but Dave recommends the Bulletproof brand since it’s lab tested to ensure low mold toxins in the beans. It also just tastes good.

Next, in a blender combine 2 cups of the coffee with up to 2 tablespoons of grass-fed unsalted butter and up to 2 tablespoons of Brain Octane Oil. If you don’t want to use the butter, a good alternative is Bulletproof grass-fed ghee. The ghee tastes amazing – I prefer it over the butter. Blend these ingredients in a blender until there is a thick layer of foam on top.

The blending is a super important part of the recipe. Don’t skip this and stir the ingredients together. It will not have the same effect.

You should start with 1-2 teaspoons of the butter/ghee and Brain Octane Oil. Work your way up to the amount you need to stay full until lunch. I use about 2 1/2 teaspoons of each.

This recipe is delicious as is, but you can also add in cinnamon to flavor the coffee.

Potential Benefits

Dave claims that people following this diet have reported amazing energy levels, improved brainpower and weight loss. He says fat is the most important and least inflammatory macronutrient, and avoiding fat is a mistake. Of course, not all fats are good for your body, but he concludes that butter is one of the “good” fats for your brain.

“For you, becoming Bulletproof might mean having more energy on less sleep, losing weight with minimal exercise, or simply feeling like the lights in your brain have turned on for the first time and you finally have the power to be your most awesome, powerful self.”

What I Did

After reading this book, I decided to make a few changes to my diet (and supplement routine), but the strangest one was drinking the butter coffee. I went online and bought the coffee, ghee and Brain Octane Oil from bulletproof.com (they have a starter kit with all 3 items as well).

My routine included drinking the coffee 3-4 mornings per week for the first few weeks. I made the coffee, starting with only 1 teaspoon each of the ghee and Brain Octane Oil. I worked up to 2 1/2 teaspoons each over a couple of weeks.

On the days I didn’t have the Bulletproof Coffee, I usually ate eggs or some other low-carb breakfast cooked with grass-fed butter and regular black coffee.


Initially, I had two issues. When I used 1 teaspoon of the ingredients, there wasn’t enough fat to keep me full until lunch. I felt kind of shaky and super hungry. This went away as I increased to using a more of the ghee and oil.

The second issue was that I had some heartburn. According to my Google research, this is normal as your body needs less stomach acid since there is no food to digest. If you smell or think about food while fasting, it can trigger the brain to tell the stomach to produce more acid, leading to heartburn. Luckily, my body figured this out after a couple of weeks, and I no longer experience heartburn.

After this initial adjustment period, I started experiencing the energy and improved brain function promised in The Bulletproof Diet. I even started saving my most difficult work tasks for the mornings when I drank Bulletproof Coffee. The tasks just seem easier and I can get through them more quickly.

I also lost a few pounds while drinking the coffee, and I notice I can easily go longer between meals without snacking. Like I said, I made a few other supplement and diet changes after reading the book as well, and one of them was trying to get more good fats into my diet. That may be the reason for the increased satiety, in addition to the coffee.

What Next?

I recommend you read The Bulletproof Diet and try the coffee. There’s so much good information in this book about small things you can do to improve your health.

If you have big things to accomplish in life, it’s worth the investment to learn about your body and health. This diet may allow you to live your most energetic and happy life.
