Bulletproof Coffee, aka butter coffee or keto coffee, is an energizing beverage made with quality fats and high-quality coffee beans.

When you drink Bulletproof Coffee instead of eating a carb-heavy breakfast, you’ll feel satisfied and energized for hours. It’s great on keto, intermittent fasting, and the Bulletproof Diet.

Coconut oil and margarine just won’t cut it. For the best results, use ingredients that will help you feel your best: clean coffee beans, pure MCT oil, and grass-fed butter or ghee. Find out how it all works below.

Where Bulletproof Coffee began

Dave Asprey was a successful Silicon Valley entrepreneur when his health really started to take a hit. He was obese, weighing in at almost 300 pounds. He was also chronically tired, and his brain function was starting to suffer.

For years, he tried restricting calories and working out every day. Nothing helped. By the time he was 30, Dave’s doctors told him he was at strong risk for a stroke or heart attack — not at some indeterminate time in the future, but soon.

Dave got the idea for Bulletproof Coffee after a trek in Tibet in 2004. At 18,000 feet above sea level and -10 degrees Fahrenheit, his energy was plummeting — until he staggered into a guest house and a local handed him a creamy cup of yak butter tea.

The biohacker in him wondered why the tea made him feel so good, and he embarked on years of research into the power behind the ingredients. Eventually, Dave substituted tea for mold-tested coffee, and yak butter for regular grass-fed butter or ghee.

Brain Octane oil was the final missing piece. And the right blend of these three ingredients (the right coffee, the right MCTs, and grass-fed butter) finally gave Dave the same feeling he first experienced in that hut high up in the Tibetan mountains. That’s how Bulletproof Coffee was born.

How does it work?

Turns out there is some powerful science behind the benefits of coffee, butter, and Brain Octane Oil. Let’s dive in:

Coffee beans and peak performance

Coffee doesn’t just taste good. It also delivers antioxidants. Caffeine keeps you alert, and it can also boost your metabolism and help you burn fat for energy.

But none of these benefits mean much if you’re drinking the wrong coffee.

Just like the food you put into your body, the quality of your coffee matters: Bad coffee can sap your energy and hurt your performance, while the right beans can give you an edge.

The problem is finding consistently good coffee. So make sure to brew with the best beans possible. Choose single-origin, small-batch Arabica beans that are tested for toxins and come from high-elevation farms.

Bulletproof Coffee Beans exceed all of these standards. Our coffee beans are expertly picked, sorted, and roasted.

Location : Bulletproof coffee beans come from high-elevation, Rainforest Alliance certified, single-origin coffee estates.

Why grass-fed butter?

Grass-fed butter gives Bulletproof Coffee its creamy consistency. It also gives you quality fats that help keep you full and fueled. It’s the key ingredient to one of the creamiest lattes you’ll ever have.

Not only that, but grass-fed butter is a good source of butyrate and contains important nutrients like vitamin A, beta-carotene, and the fatty acid CLA.

For a pantry-friendly option with almost no lactose, try Grass-Fed Ghee.

The benefits of Brain Octane oil in Bulletproof Coffee

Brain Octane oil is a key ingredient in the Bulletproof Coffee recipe for several reasons:

Purity : Brain Octane is pure C8 MCT oil derived from 100% coconut oil. It’s triple-distilled and purified with just water, heat, and pressure. That means you get pure, highly ketogenic C8 MCTs — and no coconut residue.

: Brain Octane is pure C8 MCT oil derived from 100% coconut oil. It’s triple-distilled and purified with just water, heat, and pressure. That means you get pure, highly ketogenic C8 MCTs — and no coconut residue. Quality : Brain Octane oil is held to Bulletproof’s strict quality standards.

: Brain Octane oil is held to Bulletproof’s strict quality standards. Taste: Brain Octane oil is flavorless and odorless, unlike some other MCT oils.

Different types of fats have different jobs. And because of Brain Octane’s molecular structure, it’s four times more effective than plain coconut oil at raising your ketone levels, so your body and brain can run on fat instead of sugar. This is what gives you clean-burning energy for hours at a time.

Do you have to use Bulletproof ingredients to make Bulletproof Coffee?

Authentic Bulletproof Coffee means using Bulletproof ingredients — all designed to make sure you get the most consistently amazing, frothy, energizing drink possible every time you make it.

Sure, you might get away with using generic coffee beans and coconut oil and still feel some of the same benefits. But carefully selected Bulletproof beans and the high-purity C8 MCTs in Brain Octane oil are your most reliable shortcut to great Bulletproof Coffee.

Why coconut oil just won’t cut it

Brain Octane oil is more than four times as effective as plain coconut oil at supplying energizing ketones. Throwing coconut oil in your coffee won’t give you the same effects.

After all, Brain Octane Oil is caprylic acid (C8), a special type of medium-chain triglyceride (MCT) derived from coconut oil — and not all MCTs are created equal.

That’s just one more reason why you’ll notice the difference when you make Bulletproof Coffee with the right ingredients.

Here’s a little more detail if you’re curious about the differences between MCT oil and coconut oil.

Why you should rethink breakfast

Bulletproof Coffee is breakfast — but without the added sugar that comes with some common morning staples like fruit juices, smoothies, and bread. And because of all those quality fats from grass-fed butter and Brain Octane Oil, you’ll feel full and energized for hours.

Not all fats make you fat

In fact, eating more of the right fats can be a powerful way to defeat snack cravings and fuel your brain.

Unlike many other fats, most of the high-purity C8 MCTs in Brain Octane oil go directly to your liver. Then, your body turns them into ketones that get burned for energy — not stored on your waistline.

Bonus: Because fats can make you feel full faster, you may find that you actually eat less by adding more high-quality, ketogenic fats to your plate.

But what if you don’t drink coffee?

You don’t even have to use coffee to feel many of the benefits of Bulletproof Coffee. In fact, a Tibetan tea was Dave Asprey’s first introduction to the energizing power of a cup of buttery deliciousness.

The truth is, you can make just about any hot beverage into a creamy, frothy version of itself simply by blending in grass-fed butter and Brain Octane oil. Hot chocolate, tea and turmeric tea are just a few options. Check out this recipe for the perfect Bulletproof Matcha Latte.

Getting started with Bulletproof Coffee

The best way to figure out if Bulletproof Coffee works for you is to try it. Here’s how you can incorporate Bulletproof Coffee into your day to up your energy and performance:

Get the ingredients. That means Bulletproof coffee beans, grass-fed, unsalted butter (or ghee), and Brain Octane Oil. For a convenient, blender-free option, try ready-to-drink Bulletproof Coffee Cold Brew. You can take it with you anywhere, no refrigeration needed. Try swapping your usual breakfast for Bulletproof Coffee for one week. It may take your body a while to adapt to the extra fat. Start slowly with smaller amounts of butter and Brain Octane Oil, and build up to the full amounts included in the recipe. Eat your lunch and dinner as usual, or just eat when you’re hungry. For best results, stay in the “green” zone of the Bulletproof Diet Roadmap.

Bulletproof Coffee is your new favorite breakfast

Typical breakfast staples loaded with sugar and refined carbs can spike your blood sugar. Sure, you may get a quick burst of energy, but by mid-morning, you’ll be hungry, tired, and unfocused.

Starting your day with Bulletproof Coffee, on the other hand…

Curbs hunger and snack attacks : The quality fats in Brain Octane oil help keep you full.

: The quality fats in Brain Octane oil help keep you full. Gives you mental energy: Brain Octane rapidly converts into ketones to help power your brain with high-performance fuel.

Ditch the sugar-heavy breakfast and start your day with fat for fuel. When you feel sharp and alert for hours, you’ll be glad you made the switch.

4 common questions about Bulletproof Coffee

1. Isn’t Bulletproof Coffee high-calorie and high-fat?

If you’ve ever tried a low-calorie diet, you know how unsustainable it is. You starve yourself for a few days until 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 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 steady energy, not the mid-afternoon crash from carbs in traditional breakfast foods. The MCTs in Brain Octane oil metabolize into fuel for your brain and promote thermogenesis, increasing your metabolic rate.

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.

2. 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 gives you an entirely different experience.

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. Ketones affect two hormones, ghrelin, and CCK, in a way that curbs cravings for hours. Plain coconut oil isn’t strong enough to affect ghrelin and CCK the way Brain Octane oil 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.

3. Won’t Bulletproof Coffee break your fast?

No, as long as you aren’t having protein or carbs with it. Fat doesn’t impact your blood sugar levels when practicing intermittent fasting. That means Bulletproof Coffee can actually help you extend your fast, without feeling hangry. Learn how Bulletproof Coffee complements intermittent fasting here.

4. 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 anti-inflammatory compounds like kahweol and cafestol.

That said, Bulletproof Coffee’s nutrient profile doesn’t stack up against, say, an avocado and a couple of whole eggs. It’s a tool to support ketosis, benefit from intermittent fasting, and fuel your mind and body with quality fats. You want to eat nutrient-dense, whole foods for your other meals.

If you’re eating lots of greens, grass-fed meats, 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. For even better results, follow the Bulletproof Diet (all the info is free right here). It’s an incredible way to manage weight, increase your mental sharpness, have hours of stable energy, and feel your best.

7 things you shouldn’t blend into keto coffee

Sometimes people get a little too creative with their Bulletproof Coffee. Sometimes it’s a biochemistry mistake, but sometimes it’s a culinary disaster. If you want to perform at your peak, avoid adding the following ingredients to your morning butter coffee:

1. Whey protein

Whey is not heat-stable and the IGG peptides get damaged by the high temperature of your coffee and the blender’s mechanical action. You can, however, add whey protein to an iced version of Bulletproof Coffee if you blend it gently.

If you do want a protein boost in your hot Bulletproof Coffee, opt for Bulletproof Collagen Protein — it’s heat-stable and mixes easily in hot or cold liquids.

2. Raw cream

Raw cream isn’t raw anymore once you put it in hot coffee. If you tolerate it and can find it, save this expensive, rare treat for whipping and eating cold, or on top of the coffee after it has cooled a bit by pouring it in an unheated mug.

Raw cream has more casein protein than cultured butter. Research suggests the higher amount of casein may bind to the antioxidants in coffee,which means you get less of the antioxidant benefits than you’ll get with grass-fed butter or ghee. If you must drink coffee with cream, use pasteurized, grass-fed cream — it’s a lot cheaper.

3. Soy milk

Soy is high in phytic acid and lectins, and it may affect estrogen levels if eaten in excess. Learn more about soy here.

4. Casein protein

Casein may interfere with the antioxidant benefits of coffee. Again, if you want some protein, add some Collagen Protein instead.

5. Industrial butter and margarine

Don’t do it — use unsalted grass-fed butter instead. Find out why industrial dairy is bad news.

6. Industrial nut milks

Most use low-quality nuts, and many contain questionable additives like carrageenan (which is bad for the gut and liver) or high-fructose corn syrup. It’s best to save nuts for eating, not drinking — or make your own nut milks using your blender.

7. Sugar and artificial sweeteners

If you like your coffee on the sweet side, use Stevia, xylitol, or erythritol. Check out this full list of Bulletproof-approved sweeteners — and which to avoid.
