Keto coffee is simply regular coffee with added healthy fats. Simply put, it's coffee with butter or coconut oil. Fat infused coffee was made popular by Dave Asprey as Bulletproof Coffee. In this article we will take a closer look at why you should be adding fats into your daily cup of coffee.

Why Would You Want to Put Butter in Your Coffee?

Buttered coffee is one way to supply the body with more fats in order to induce the state of ketosis. This state reprograms the body to rely on ketones (by-products of fat breakdown) as the main energy source as opposed to glucose (from carbohydrates). More on ketosis later.

Keto coffee (fat infused) is healthier than regular coffee. It can offer way more energy than that overpriced “gourmet” cup of coffee you regularly line up to get on your way to work.

Bulletproof Coffee Review: How Does Bullet Proof Coffee Work?

Bullet coffee is a type of coffee that is made from a blend of organic coffee beans and unsalted butter. It’s brimming with caffeine and healthy fats. Take this potent keto coffee blend in the morning, after an entire night of fasting, and your metabolism will soar through the roof.​

Caffeine is a stimulant. It will raise your metabolism and make you more alert and focused.

Fats from organic butter or mct oil/coconut oil will supply your body the energy it needs.

When your metabolic rate is high, you burn more calories. Ketones from fats will be able to supply a steady stream of energy better.

However, when you eat too much carbs and your body uses glucose to drive metabolism, you will typically experience a tidal wave of energy, and then a crash within a few minutes. The result? Drowsiness, irritability, poor focus and low energy.

These do not happen if your body uses ketones for fuel.

These effects will help you be able to fast all day. This simple cup of keto coffee will help you breeze through a 10+-fasting hour for the rest of the day.

With bullet coffee, there is no mid-morning slump that commonly happens after a carb-rich breakfast. There would be no mid-morning craving for sweets, either when on a bulletproof coffee diet.

Because your appetite is suppressed, you’d be satisfied with smaller portions during lunch. Around dinnertime, you won’t feel ravenously hungry. Finally, with bulletproof coffee diet regimen as part of your ketogenic diet, you will still have energy to do more before hitting the sack.​

What Are the Bulletproof Coffee Benefits?

There are many benefits of bulletproof coffee. Taking just one cup of keto coffee a day can help achieve these:

Pregnenolone Weight Loss Regimen The Master Hormone for Fat Loss progress

Fat Loss

On ketosis, the body is burning fats for fuel. Excess fats in the body will be mobilized better and put to good use. Fats in the diet will be metabolized better. Fat stores in the body won’t increase when drinking bulletproof coffee. Weight loss happens as the body learns to work with fats better and more efficiently.

Numerous studies demonstrated that taking healthy fats will actually trigger fat burning rather than more fat storage. One study showed that taking mct oil (medium-chain triglyceride) resulted in greater loss of fat (adipose) tissues. You can get more mct in the diet by drinking coffee with butter and coconut oil, both being rich sources of mct.​

Sustained Energy

Energy from fats is more efficient than energy from glucose. Several studies have demonstrated this benefit already.

With medium chain fatty acids (MCFAs), the rate of oxidation is rapid. This leads to higher energy expenditure. MCFAs are broken down into ketone units. These ketones are readily absorbed by the body compared to regular types of oils.​

This rapid absorption provides greater overall energy. Greater absorption means that the cells are able to process the ketones and use it as fuel for various bodily processes.​

Ketones provide a steady supply of energy. It does not cause the high that follows a major intake of glucose then followed by a sugar crash. Ketones are more efficient and consistent in providing energy to the cells.​

The caffeine in coffee also provide a major boost to your energy, but for some people it might be too jittery and decaf coffee would be preferred. Our favorite non-jittery natural energy booster is kratom leaf. Checkout for more information on this plant.

Protects Against Heart Attack

Numerous studies have already shown that eating saturated fats reduces the body’s risk for the development of coronary heart disease. Contrary to popular belief, there are kinds of fats that are good for your body. Saturated fats are not always the culprit for heart diseases. In the right amounts and from the right source, saturated fats can promote better health.

In fact, the saturated fats in coconut oil and butter can also improve testosterone levels.​


What Are the Main Ingredients of Bulletproof Coffee?

Keto coffee has 3 main ingredients. There is coffee, mct oil (coconut oil) and butter from grass-fed animal source.

MCT Oil (Brain Octane & XTC Oil)

Coconut oil is actually a type of MCT or medium chain triglycerides. Coconut oil contains 65-80% MCT. This healthy oil helps with fat loss and better body fat mobilization. 

Bulletproof sells Brain Octane, which is a more refined MCT oil that contains more of the type of fatty acid that is most effective for brain energy (ketones). They also sell XTC oil which is regular MCT oil.

Grass-Fed Butter

Butter is a healthy kind of fat. People churned their own butter in the old days and the serious illnesses plaguing us today were not as prevalent back then.

Butter started to be cast in a bad light because of the source. Cows from which milk for butter are obtained are massively treated with artificial hormones.

These artificial hormones induced greater milk production. The artificial hormones get mixed into the milk and end up in products like butter.​

Another reason for butter’s terrible reputation is the wrong notion that fats are unhealthy – an idea that was perpetuated by the US Department of Agriculture in their efforts to promote wheat, which is high carb.

This is why it is important to choose butter made from the milk of grass-fed cows. This means no exposure to toxins and artificial hormones.​

Butter made from grass-fed cows is also higher in nutrient contents. It is loaded with nutrients such as omega-3 fatty acid and vitamin K2. The quality of the nutrients in grass-fed butter is also more superior.​

A Bulletproof coffee keto breakfast can boost metabolism and energy for the day better than the usual carb-laden breakfast fare.

How to Make Bulletproof Coffee

To make delicious and healthy Bulletproof coffee, you will need:

  • Coffee, 2 Cups
  • Grass Fed Unsalted Butter, 2 Tablespoons
  • Organic MCT Oil or Coconut Oil, 2 Tablespoons
  • Heavy Cream, 1 Tablespoon
  • Vanilla Extract, 1 Teaspoon

These ingredients for bulletproof coffee recipe are readily available when purchasing coffee starter kits for keto coffee. These kits already have keto approved oils to add. The kit also contains upgraded coffee, which is more likely to be organic and healthier than ultra-processed ones from the grocery.

Put coffee (liquid form) in a blender. Brewed keto coffee is much better than instant coffee. If possible, choose coffee from organically grown products. Coffee is good for health because it is a natural stimulant. It jump starts the body’s processes, including metabolism.​

To make the liquid coffee, place a few tablespoons of coffee in a filter. Pour hot water over it slowly to allow the flavors and nutrients to leach out slowly from the coffee granules. Or, you may simply brew coffee and use this for the recipe. After that, proceed to the next steps of creating bulletproof coffee recipe.

Add coconut oil in a blender. Regular blenders may be used to mix butter coffee. However, the oil can cling to the sides of the blender and make cleaning difficult.

An immersion blender would be better. This will help produce a smooth and creamy bullet coffee consistency. Regular mixing with a spoon as in the usual coffee will result in unappealing lumps.​

Add 2 tablespoon of grass-fed butter and vanilla extract. Add heavy cream. This will give coffee a creamy consistency. Get an immersion blender and mix until everything is well incorporated into a smooth, rich drink.​


Butter in coffee is a good way to get more healthy fats. This helps to be able to reach ketosis without worrying about negative side effects like more fat storage.

One serving of keto contains 255 calories, 9 grams of protein, 1 gram of net carb.​

Maintaining Your Ketogenic Diet With Other Food for Ketosis

Aside from the ingredients above in creating a serving of keto coffee, some prefer to add more ingredients. Some people add keto creamers to their coffee in order to increase the fat contents. Adding a small teaspoon of the wrong kind of coffee creamer can upset the balance you are trying to achieve. A small amount can raise carbohydrate levels and inhibit the state of ketosis.

The use of keto coffee creamers is also helpful for those who have trouble staying on the keto track. Most keto creamers were made from organic, grass-fed butter. This butter is rich in CLA or conjugated linoleic acid. This is a type of fatty acid that research demonstrated to be effective in inducing fat loss. People who do not have time to hit the gym or spend an hour or two exercising will find adding keto creamers to be helpful in burning excess fat and reducing weight.​

Aside from keto coffee creamers, taking keto snacks also helps. These snacks can help you combat the sugar cravings that may arise while you are in keto state. It is difficult to stay on track and be on ketosis if your mind and body starts craving for food. Eating keto-approved snack bars such as Adapt bar helps address these concerns and still remain in ketosis.​

Each keto snack bar contains nutrients in the right amounts to help maintain ketosis. However, you do not have to starve yourself just to maintain your ketotic state. All you have to do is make sure your fat intake is way greater than your carb intake. Balance things out by taking moderate levels of proteins.

Aside from keto creamers and keto snack bars, you may also add some healthy foods to further boost health. Eat foods such as Brazil nuts, avocados and oily fishes like salmon. These contain nutrients that may help in achieving and maintaining ketosis. These foods also have a positive impact on testosterone levels.​

Being healthy is not just about eating one type of food or following only one specific low carb diet. Keto coffee can help in promoting weight loss and better health. The taste does require some getting used to. That is a small price to pay for a healthier future.​
