If you love coffee, then you’re probably passionate about the beans you buy and the way your brew it. Personally, I prefer my coffee strong, made in a French press, with half a teaspoon of sugar and a splash of 1 percent milk. Starting tomorrow, I’m going to be trying something new with my coffee.

I’ll be trying Bulletproof Coffee, a method of making coffee that’s supposed to boost your physical and mental performance. To make Bulletproof Coffee you need three ingredients: single-origin good coffee beans, butter from grass-fed cows, and a medium-chain triglyceride oil. The method for brewing and putting the coffee together was created by Dave Asprey, whose story was recently told by Fast Company.

Asprey was trying to recreate the same life-changing effects he got from the yak-butter tea he drank in Tibet when he was learning to meditate. The tea gave him much more energy and he “just felt so good.” Asprey, a cloud computing pioneer, figured out how to replicate those benefits with coffee when he returned to California. He called his concoction Bulletproof Coffee and posted his recipe for free online in 2009.

Asprey has turned his method for brewing coffee and then adding butter and triglyceride oil into a booming business. He sells Bulletproof Coffee Beans and something he calls Brain Octane Oil, as well as other products that can be used with the method on his Upgraded Self website. But, you can try the method with products you can buy at Whole Foods or other organic and natural products store.

So far, this all sounds like a gimmick, doesn’t it? I would think so if it wasn’t for one thing. My friend Amanda Feifer O’Brien, the fermenting expert I’ve told you about before, tried it for a week and claims it’s “legit.” Amanda is very conscious about what she puts in her body, eating a diet that’s heavy on gut-healthy ferments. When she said she was trying it, it got my attention more than any marketing campaign ever could have.

Amanda didn’t buy the Bulletproof brand ingredients. She used a high-quality, single-origin coffee, cultured butter part of the week and then Kerrygold butter for the rest of the week, and Dr. Bronner’s unrefined coconut oil that she bought at Whole Foods.

After trying the method for a week, she wrote a post on her Phickle blog, journaling her first week of drinking butter coffee daily and the effects it had on her. She had some stomach discomfort the first day, but her husband did not. It seems the stomach discomfort was worth getting through however, because Amanda reports what she describes as “intense satiety.” She rarely got hungry and craved mostly raw veggies and water when she was hungry.

Other positive effects were improved mental clarity, more energy, a sunny outlook, high productivity and less distractibility. I could definitely do with a huge dose of all of those positive effects.

Amanda did experience a few cons besides the first-day stomach issues. She had trouble sleeping on a couple of evenings and was extra thirsty. She also said that she didn’t always want to drink something hot on a summer’s morning. She’s not a regular coffee drinker, though, and didn’t usually start her day with a hot beverage. She’s going to try it next with tea.

I’m going to start with the Bulletproof Coffee tomorrow morning, and I’ll keep a diary like Amanda did. Look for a post next week letting you know how it went, even if it goes poorly.
