Fat Coffee: The “Science” Behind Bulletproof Coffee

Contrary to popular belief, fat is not actually bad for your health. This misconception applies to coffee as well that is often to blame for rapid heart beats and insomnia.

Not knowing their other benefits, these two have never been advisable for working out, until recently – in the form of the fat infused coffee.

What is Fat Coffee?

Fat coffee, also known as ‘butter coffee’ and bulletproof coffee or keto coffee, was invented by Dave Asprey, an entrepreneur and biohacker. What inspired him was a yak-butter tea given to him by a local in Tibet back in 2004.

At that time, he was suffering from obesity. It affected his mental and physical functions.

He was surprisingly refreshed by that cup of tea that he had to figure out what made it do what it did. When he came back home, he did a lot of experiments and came up with his bulletproof coffee concept in 2009.

The coffee is the core of his bulletproof diet, which promoted high fat, low carb and  moderate protein consumption.

What separates it from a regular coffee is its fat content. This is because fat plays a big role in ketosis, which is what you are after in intermittent fasting and ketogenic diets.

How is ketosis healthy?

Low carb, high fat, moderate protein – this is the basic rule of ketogenic diets and other types of low carb diets. When there is not enough carbohydrates to get energy from, the body switches to turning fats into ketone bodies for energy.

This can be either fats consumed from your diet, or the excess fat on your body. This state is called ketosis. Ketone bodies or ketones have a number of amazing benefits and can even be supplemented as exogenous ketones.

For those who wish to lose weight, the good news is that ketones can decrease your appetite so you will eat less. Aside from this, being in ketosis means your body is burning fats for energy (goodbye stubborn belly fat!!).

Ketone bodies are also easier for the body to convert into energy and protects the mitochondria (this is where ketones are converted to energy that can be used). The brain uses ketone energy and it is actually its prefered fuel, so it will run more efficiently with the use of ketone bodies.

So basically, ketosis is when the body uses ketone bodies for energy instead of glucose. They both function the same way but using supplemental ketone bodies has added benefits.

Drinking a high fat keto coffee will help you enter into a state of ketosis faster, and even making people not following a ketogenic diet produce some ketones.

What’s in “fat coffee”?

The ingredients in a fat infused coffee aim to give you more energy and more capability to perform well physically and mentally. It consists of three essential ingredients:

1. Coffee (duh.)

The most obvious ingredient is of course, coffee beans. But not any coffee will do well. Low quality coffee can do the opposite of what you would want to achieve – it can drain your energy and thinking capacity as many of them contain mold.

It is recommended to choose 100% Arabica beans that are mold-free to be on the safe side. This type of coffee bean is of higher quality compared to Robusta, and it is less acidic.

There are two things people worry about when it comes to coffee: dehydration and caffeine’s effects.

Does coffee really cause dehydration? Well, contrary to popular belief, coffee doesn’t cause dehydration. In fact, it has several benefits for workouts.

What about caffeine? With the right amount of caffeine, it could actually make you more awake and alert and make you feel energized and less tired.

Caffeine has also been proven to increase ketone body synthesis. This, together with fats, is the perfect combination to promote ketosis in your body.

2. Grass-fed butter

Butter is commonly perceived as a big no-no for health-conscious individuals because it is wrongly known to be unhealthy due to its saturated fat content.

But according to recent studies, the fat found in butter, conjugated linoleic acid (CLA) can actually cause fat loss as well as being beneficial for the heart.

Grass-fed cows produce butter that has more CLA content as well as several other nutrients such as healthy fatty acids, beta-carotene, vitamin A, E, K, and D. The saturated fat content of butter also has been shown to relate to higher testosterone levels. Higher levels of testosterone means better results from your muscle building workouts.

Grass-fed butter also contains a short-chain fatty acid called butyrate. This fatty acid has been proven to promote good brain health and reduce the risk of brain diseases as well as some cancers.

The plus side of having butter in your coffee is that it gives a creamy texture to your drink and makes it taste a whole lot better!

3. MCT oil

Another good source of fats, medium chain triglyceride, aka MCTs, from MCT oil or coconut oil (less concentration) has a number of benefits such as weight loss, better brain function, higher energy, and may help prevent some diseases such as cancer and diabetes.

Unlike long-chain fats, MCT does not get stored as fat deposits. They instead go straight to the liver and are converted into ketones. Ketones are especially good sources of energy for those with neurological disorders like Alzheimer’s and Parkinson’s and can often reduce the negative symptoms from these diseases when consumed.

What fat coffee can do

It will help you burn fat (to an extent)

The concept of eating fats makes you fat has already been debunked. In fact, the ingredients in fat coffee that cause fat loss are both fat sources. As already mentioned, the CLA in grass-fed butter can cause fat loss. MCT from coconut or MCT oil has also been found in a study to prevent obesity by decreasing body weight gain while increasing fat loss.

Skipping your meal while drinking keto coffee will help you undergo ketosis and switch your body to fat-burning mode. Consuming fat also makes you feel full quicker so that you won’t have the urge to eat for a while. All these reasons make the fat coffee a fat-burning coffee.

IMPORTANT CAVEAT: despite its fat-burning properties, health fats are still fat. So, consuming hundreds (or more) calories worth of MCT oil and butter in the morning isn’t going to magically trigger weight loss. (quite the opposite). Those are still calories that can contribute to weight gain, and as such you’re going to have to burn them somehow.

I mention this because there is a tendency among advocates of keto/paleo/Bulletproof diets to ignore the simple fact that fats contain calories, and eating a caloric excess will cause weight gain.

It will give you more energy

Too much caffeine can lead to adverse effects such as dizziness and diarrhea. But the right amount of caffeine, no more than 400mg a day (around 4 cups of coffee), can give you a surge of energy. Moreover, if you add sources of fat such as butter and MCT oil, you can get more energy from this drink than you actually would from a cereal or pancake breakfast.

Fats are calorie-dense nutrients, much more so than carbohydrates. In fact, 1 gram of fat has 9 calories compared to 4 calories from carbohydrates. Hence, drinking the fat coffee will keep you energized for longer while being in ketosis.
