What Is Bulletproof Coffee?

Bulletproof coffee has been around long enough that most people have heard of it, even if they have never tried it. It looks unusual (coffee blended with fat has no obvious visual appeal) and the concept can seem strange if you are new to it. But it has a genuine following among people who find it works well for them. Here is a straightforward guide to what it is, why people drink it, and how ghee fits in.

Where Did Bulletproof Coffee Come From?

The concept was popularised by Dave Asprey, an American entrepreneur and biohacker, in the early 2010s. He was inspired by drinking tea with yak butter at high altitude in Tibet, which is a traditional practice in that region for exactly the reason you might imagine: fat provides slow-burning fuel in cold, high-altitude conditions. He adapted the idea for coffee with grass-fed butter and MCT oil.

The underlying idea predates Asprey by centuries. Adding fat to hot drinks is traditional in many cultures: butter tea (po cha) in Tibet, coffee with butter in parts of Ethiopia, and ghee stirred into warm drinks in Ayurvedic practice. The biohacking community repackaged and popularised something that many cultures had known for a long time.

What Goes Into Bulletproof Coffee?

The original recipe calls for freshly brewed coffee, grass-fed butter, and MCT oil (a concentrated form of medium-chain triglycerides, usually derived from coconut oil). These are blended together until frothy and creamy, which produces something that resembles a latte in texture. The blending is important: it emulsifies the fat into the coffee rather than leaving it sitting in a separate layer.

Can You Use Ghee Instead of Butter?

Yes, and for several reasons it is a better choice than butter. Ghee contains no lactose or casein, which makes it more digestible and suitable for dairy-sensitive people. It blends more smoothly because it contains no water. The flavour is nuttier and more complex than butter, which works well with coffee. And if you are already using ghee as your main cooking fat, it is one ingredient rather than two.

The ratio to use is roughly one teaspoon to one tablespoon of ghee per cup of coffee, depending on your preference. Start with less and adjust.

What Does It Taste Like?

When properly blended, bulletproof coffee is rich, creamy and surprisingly satisfying. The fat from the ghee gives the coffee a body and texture that regular black coffee doesn't have. The flavour is distinctly coffee, with a buttery, nutty undertone. Many people describe it as the most satisfying way they have found to drink coffee, particularly in the morning.

Is It Good for You?

For some people, yes. The fat slows the absorption of the caffeine in the coffee, which produces a more gradual, sustained alertness rather than a sharp spike followed by a crash. People following ketogenic or low-carbohydrate diets use it as a way to consume fat and maintain ketosis. Some people use it to replace breakfast when they are practising intermittent fasting.

It is not a magic drink and it is not suitable for everyone. It is high in calories and fat. Drinking it as a breakfast replacement means you are not eating breakfast. Whether that is a good idea depends on your individual diet, health and goals.

How to Make Bulletproof Coffee With Ghee

Brew a strong cup of coffee (filter, French press or espresso all work). Add one teaspoon of ghee and one teaspoon of MCT oil or coconut oil if you have it. Blend for 20 to 30 seconds using a stick blender, a standard blender, or a milk frother. Pour into a mug and drink immediately. If you don't blend it, the fat will float on top rather than integrating into a creamy drink.
