Why add fat to coffee at all?

The Oromo people in Ethiopia are the first known to combine coffee with fat. They used to grind ripe coffee cherries and would add them into animal fat. They rolled the paste in balls which nomads carried with them and consumed for energy. In recent times, the idea of combining coffee and fat has been made popular by Dave Asprey and his Bulletproof Coffee brand.

The idea of adding MCT oil to coffee is popular in the paleo and keto diets. The combination is promoted as a substitute for a carb-heavy, grain-filled meal. It claims to suppress your appetite and provide long-lasting energy without a sugar crash. The fat in the oil curbs your hunger, while the coffee provides better mental focus. If MCT oil works so well, will olive oil in coffee work the same way?

Olive Oil in Coffee – 3 Reasons to Add It

Fat in Coffee
Not the most appealing sight

You may be surprised to hear that the taste of olive oil when mixed in with coffee is not overpowering (at least in our test); in fact, it’s delicious and full of health benefits. It can help you get a much-needed dose of healthy fats, focus better in the morning, and aid in weight loss.

Loaded With Antioxidants

Olive oil and coffee are both loaded with polyphenols. Polyphenols are the antioxidants that give the real, extra virgin olive oil that characteristic bitter and pungent kick. It’s important to look for extra virgin olive oil since it’s the only one containing the main phenolic compounds, hydroxytyrosol and oleuropein. They also degrade quickly, so it’s crucial to press the olives within 24 hours of picking. 

Research has shown that the polyphenols in olive oil have a powerful antioxidant activity. The consumption of olive oil helps with atherosclerosis and cancer prevention. It’s also proven to have a high anti-inflammatory and antimicrobial activity.

Helps With Weight Loss

Olive oil for weight loss has the same effect as the popular MCT oil. Hunger is the result of the blood sugar falling and the cells absorbing glucose from the blood. Olive oil keeps the blood sugar from crashing and suppresses glucose absorption for an extended period. Unlike coconut oil which is a popular source of MCTs, olive oil contains unsaturated fat which is the healthiest dietary fat.

A study conducted by the Technical University of Munich(1) has shown that even the aroma of olive oil can aid in weight loss. A focus group showed higher levels of the satiety hormone serotonin in their blood and a lower daily caloric intake after consuming olive oil.

Froth from the fats
From unsightly to delicious?

Added Nutrients In Your Morning Brew

Olive oil has significant nutritional value that includes monounsaturated fats.  These healthy fats help reduce inflammation and lowers your risk of heart disease – you don’t need to feel bad about adding a tablespoon into your hot coffee! They also help balance your total cholesterol by lowering the LDL (bad) cholesterol and improving the HDL (good) cholesterol. 

A reasonable amount of vitamin E and K are also contained in olive oil.(2) Vitamin E works as an antioxidant and helps protect the cells from the damage caused by free radicals. Vitamin K is vital for keeping your bones healthy, normal blood clotting, and wound healing.

How To Make Your Coffee with Olive Oil

Adding olive oil in coffee is pretty straightforward. It sounds exactly as described. And if you are a seasoned Bulletproof Coffee ‘barista’, all you need to do is to substitute MCT oil with extra virgin olive oil. Now, the key step is knowing how much olive oil to add without compromising the taste of your morning coffee.

The Results

Olive Oil in Coffee
The final product


The taste can best be described as creamy, nutty, and sweet at the same time. My partner and I did not taste the olive oil at all. We used an organic olive oil brand carried by Costco and ghee. It might be down to us using a mild flavored oil. To be completely honest, most of the flavor came from the ghee and the coffee. Near the end, it felt a little oily and peppery at the back of the throat but did not taste bad at all.

Energy Levels

We ran this test for a week in the hopes of some great results. It did help keep satiety at bay; we felt fuller for longer and did not have terrible sugar crashes. Now, it’s hard to determine if our energy levels have increased more than usual. It really depended on the amount and quality of sleep we had the night before. Bad sleep = low energy, period.

Final Thoughts: Olive Oil in Coffee

Coffee and Olive Oil

Here’s our summary on experimenting with olive oil in coffee. We can only confidently comment on its taste (the rest is anecdotal and should be tested methodically by an expert).

Keeping in mind the slightly bitter notes, peppery qualities of olive oil, we expected it to overwhelmingly take over the beverage’s flavor. To our shock, it was muted, and the result was pretty pleasant. It tasted like buttery coffee due to the ghee, but we did not enjoy the oily mouthfeel after.


Can You Put Olive Oil in Coffee?

You’re free to put olive oil in coffee as long as you do it slowly and work your way up. Start by adding no more than a tablespoon for at least a week and let your body adapt. You’ll experience the benefits from olive oil without sacrificing the taste of your coffee.

How Much Olive Oil Can I Put in My Coffee?

If you’re just starting, it’s not recommended to use more than 1-2 tablespoons of olive oil in your coffee. While it depends on personal preference, keep in mind that too much olive oil can leave your coffee tasting oily and undrinkable. Both coffee and olive oil are laxatives, so we don’t recommend going overboard.
