6 Common Questions About Bulletproof Coffee

Bulletproof Coffee has already changed hundreds of thousands of people’s lives. You owe it to yourself to see how good you’ll look and feel after drinking it for a couple weeks. It’s powerful stuff.

It also goes against almost every mainstream dietary recommendation out there. Dosing your coffee with butter and oil every morning can seem understandably strange at first. Won’t eating fat make you gain weight? How many calories are in a cup of BP Coffee? You shouldn’t drink your calories because it isn’t satisfying…right? Couldn’t you be getting more nutrients and satisfaction from other foods?

Let’s address a few of the common concerns about Bulletproof Coffee. Hopefully you’ll come away from this article ready to take the plunge. If you’re not a fan, you can always stop…but I’m pretty confident you’ll like it.

What is Bulletproof Coffee?

Bulletproof Coffee is a blend of mold-free and mycotoxin-free coffee, grass-fed butter (or grass fed ghee), and Brain Octane Oil (not coconut oil, which is an important distinction). Bulletproof Coffee is carefully designed to:

  • keep you full for hours
  • curb hunger
  • promote mental clarity
  • increase fat burning
  • support your hormones
  • taste awesome


Isn’t Bulletproof Coffee too many calories? And too much fat?

If you’ve ever tried a low-calorie diet you know how unsustainable it is. You starve yourself for a few days, and eventually (probably at nighttime, when the ventral tegmental area – the part of your brain that controls willpower – has used up its energy for the day) your friends order a pizza, your low-calorie plan falls apart, and you eat everything in sight. Plus, because your body slows your metabolism down to match your decreased calorie intake, you end up gaining more weight than you lost. Thus begins a painful cycle of yo-yo dieting.

In the long term, restricting your calories like that won’t help you lose weight. Counting calories doesn’t work because your biology is far too complicated to reduce weight loss to “calories in, calories out.” A better approach is to optimize your metabolism and hormones, both of which contribute to fat burning, while curbing your hunger with food that keeps you full for hours.

Bulletproof Coffee checks those boxes. The saturated fat and cholesterol in the grass-fed butter support your hormones (all steroid and sex hormones, including fat-burning testosterone, come from cholesterol) and provide a slow burn of steady energy that’s an upgrade over the carbs in traditional breakfast fare. The Brain Octane’s medium chain triglycerides (MCTs) metabolize into fuel for your brain and promote thermogenesis, increasing your metabolic rate. Plus, coffee itself increases fat burning and metabolism [1].

All that translates to feeling full for hours while burning fat. Don’t fear the calories or fat in Bulletproof Coffee. They’re doing a lot of good for you.


Drinking calories is unsatisfying, right?

If you’re talking about fructose-laden juice or soda, yes. Most sugary drinks give you a quick burst of energy…then you crash and get hungry an hour later. But Bulletproof Coffee is a different beast entirely.

This is where Brain Octane really works its magic. It rapidly converts to ketones, which are an alternative to the glucose your body usually uses for fuel. Brain Octane is a pure extract of the strongest ketone-producing fats in coconut oil, and it affects two hormones, ghrelin and CCK, in a way that turns your hunger off for hours. Plain coconut oil isn’t strong enough to affect ghrelin and CCK the way Brain Octane does.

In this case, drinking your calories can be more satisfying than eating them. You can read more about the science behind Brain Octane and hunger suppression here.


Does Bulletproof Coffee work with fasting?

Fasting is as great way to slow aging. It promotes autophagy – that’s when your cells clean themselves out and recycle damaged parts into pristine ones. Fasting also has mental and fat-burning benefits.

Won’t Bulletproof Coffee break your fast?

No, as long as you aren’t having protein or carbs with it. The key is insulin. Insulin is famous for regulating your blood sugar, and it’s also what turns autophagy on and off. Your insulin levels drop while you sleep, during which time autophagy cleans out cellular waste and improves your brain function. Traditionally, in the morning, your breakfast will increase insulin and turn autophagy off. But if you keep insulin low (by fasting) you can keep that improved cellular function and mental clarity going.

Carbs raise your blood sugar and insulin levels when they convert to glucose. Protein does the same – your body converts it to glucose through a process called gluconeogenesis, which is inefficient but enough to raise your insulin.

Fats, on the other hand, don’t impact your blood sugar levels. That means you can stay in a fasted state as long as you’re only eating fat – which is why Bulletproof Coffee is such a good complement to intermittent fasting. Again, you can read more about the science behind intermittent fasting (with plenty of references) here.


Wouldn’t I get more nutrients eating whole foods for breakfast?

Potentially. Grass-fed butter is packed with beneficial fatty acids and several vitamins, especially compared to grain-fed butter. You can see the difference in vitamin A content – grass-fed butter has a sunny yellow color that conventional butter lacks. Coffee itself is full of polyphenols and unique cancer-fighting oils like kahweol and cafestol.

That said, Bulletproof Coffee’s nutrient profile doesn’t stack up against, say, an avocado and a couple whole eggs. But that doesn’t really matter if you’re eating nutrient-dense foods for your other meals. If you’re eating lots of greens, grass-fed beef/lamb, eggs, quality fats, and organ meats, all seasoned with a solid dose of salt, herbs, and spices, you’re going to far surpass your daily need for most nutrients. A less nutrient-dense morning meal isn’t an issue.

You owe it to yourself to try Bulletproof Coffee. It may sound like a strange way to start your day, but if you make it right you might be surprised by how incredible it makes you look and feel. And for even better results, pair it with the Bulletproof Diet (all the info is free right here). Expect to effortlessly lose weight, increase your mental sharpness, have hours of stable energy, and feel great every day. Give it a try. It can change your life.

Thanks for reading and have a great week.
