A quick update before you read:
I drank bulletproof coffee most mornings while I lost over 130 pounds. I don't drink it anymore. I'd rather eat my calories than drink them, and I have kids now. They eat a real breakfast, and I eat with them.
If you want to try it, everything below still holds up. And if you came here looking for something that helps with weight loss, the coffee was a small part of what worked for me. The bigger part is in these five episodes.
There are over 2,000 episodes of my podcast, Consistent by Primal Potential. These are the five I'd hand a friend who asked me where to start.

Most people drink it in place of breakfast. A lot of people find the fat keeps them full through the morning, and it has no sugar or carbs, so it's a better option than a bagel or a drive-through breakfast. For me, it replaced a Chick-fil-A breakfast.
Why grass-fed butter: Butter from grass-fed cows has more omega-3s and vitamins than butter from grain-fed cows. I used Kerrygold unsalted, which you can find at most grocery stores.
Why MCT oil: MCTs are a type of fat your body uses quickly for energy, which is why so many people say it gives them steady energy in the morning. It's harder to find in a regular grocery store, so I always bought mine online.

A lot of people are nervous about putting butter in their coffee. The worst case is you take a sip and don't like it. If you hate it, pour it out.
Coffee is water, and butter and oil are fat. If you stir it, the fat floats on top and your first sip is pure fat. Use a blender or an immersion blender. When I traveled, I packed a handheld frother. It has no blade, so it's easy to get through security. Here's the frother I recommend.
A common recipe online is 2 tablespoons of butter and 2 tablespoons of oil. I wouldn't start there. Start with a teaspoon of each and adjust from there, the same way you'd figure out how much cream you like. If MCT oil upsets your stomach, use less.
Melted butter turns solid again as it cools. Take it from me: drink it while it's hot.
Two tablespoons of butter and two of oil is around 400 calories. That's a meal. If you add it on top of your usual breakfast without changing anything else, you're giving your body a lot of extra fuel. Pay attention to your results, and if you're not making progress, it may be too much.
There's no single right number. It depends on what else you eat, how active you are, and how you handle caffeine. Keep in mind that one cup with a couple tablespoons of fat is a meal on its own, so more than one adds up fast. If you can't fall asleep at night or you feel jittery, it may be too much.
Start with about a teaspoon of butter and a teaspoon of oil. Work up slowly to what tastes good and feels good to you. You don't need to start at the 2 tablespoons of each you'll see in a lot of recipes.
Yes. Any calories take you out of a fast, and liquid calories count.
You can. Coconut oil is about 60% MCTs, so MCT oil is the more concentrated choice. Coconut oil is easier to find in a regular grocery store.
Try it without first. You might be surprised how good it is on its own. If you do add one, use a sweetener with no calories.
Kerrygold butter and coconut oil are at most grocery stores. MCT oil is easiest to find online. Here's the one I like, because the bottle is glass.
