Why Put Butter in Coffee

Coffee has become an extremely popular beverage across the world, with people consuming it on a daily basis. While many enjoy their coffee black, some choose to enhance the flavor by adding ingredients like sugar, cream, or milk. However, a unique coffee trend has emerged in recent years – adding a pat of butter to coffee.

This unconventional practice, known as bulletproof coffee or butter coffee, was popularized in Silicon Valley and among biohackers. It involves blending grass-fed unsalted butter or ghee into black coffee to create a creamy, latte-like beverage. Proponents of butter coffee claim that it provides a variety of cognitive and health benefits beyond a normal cup of joe.

Adding butter to coffee may seem counterintuitive, but advocates say the fats help curb hunger and provide sustained energy. The medium-chain triglycerides (MCTs) found in butter and coconut oil also may improve mental clarity and focus.

Background on Butter Coffee

Background on Butter Coffee

While butter coffee may seem like a recent health fad, the practice of mixing butter into coffee has a long history spanning over a thousand years.

  • The earliest origins can be traced back to ancient Ethiopia in the 9th century, where people would often blend coffee grounds with clarified butter or ghee. This combination was found to provide a boost of energy and mental clarity.
  • In the Middle Ages, populations throughout the Himalayas and Tibet discovered benefits of adding yak butter to coffee. The beverage became a common morning ritual to start the day before long treks at high altitudes.
  • Mixing butter and coffee is still customary in many parts of Asia today. For example, in Malaysia and Singapore, “Kopi Gu You” is made by adding a slice of butter on top of sweetened condensed milk coffee.

The recent popularity of butter coffee in the West can be attributed to Dave Asprey, founder of Bulletproof. After traveling to Tibet in 2004 and trying yak butter tea, he began experimenting with adding butter to coffee for cognitive benefits.

  • Asprey claims he lost 100 pounds and increased his IQ by 20 points after starting his butter coffee routine. This inspired him to share it with Silicon Valley tech workers looking to biohack their brains.
  • By 2009, Asprey launched his signature Bulletproof Coffee made with grass-fed unsalted butter and MCT oil. It became a staple beverage among biohackers and keto dieters.

The high-fat coffee drink took off as it aligned with several health trends – the rise of ketogenic and paleo diets, interest in nootropics and smart drugs, and the popularity of intermittent fasting.

  • Keto and paleo followers used butter coffee to get an energy boost while staying in ketosis. The fats helped curb hunger during fasting periods.
  • Biohackers added MCT oil hoping to power up mental performance and focus. The butter provided creamy texture and flavor.

So while butter coffee may seem like a modern fad, its origins trace back centuries. The combination of butter and coffee continues to be popular worldwide thanks to its purported energy and cognitive benefits.

Benefits of Adding Butter to Coffee

Adding butter or ghee to coffee may seem unconventional, but studies show it can provide several health and cognitive benefits supported by scientific research.

Provides Sustained Energy

  • The fats in butter are broken down slowly, leading to steady energy over a few hours rather than a quick spike and crash from sugar or cream.
  • Medium-chain triglycerides (MCTs) from butter or coconut oil fuel the body and brain. MCTs are easily digested and absorbed, providing quick and efficient energy.
  • The combination of caffeine and MCTs can improve mental clarityfocus, and performance on cognitive tasks compared to coffee alone according to some studies.

May Help With Weight Loss

  • Fats are satiating, which reduces appetite and overall calorie intake throughout the day. One study found MCT oil consumption decreased food intake by 256 calories per day.
  • Ketones produced from MCTs may increase fat burning. A study found MCT oil boosted fat burning by 120 calories per day compared to olive oil.
  • Replacing carbs with the fats in butter coffee can help the body enter nutritional ketosis, which promotes fat burning.

Improves Cognitive Function

  • MCTs can be used directly by the brain for fuel and may improve focus and mental clarity. One study showed improved cognition in Alzheimer’s patients after MCT supplementation.
  • Ketones provide an alternative energy source for the brain and can improve cognitive performance in those with impaired glucose metabolism according to studies.
  • The caffeine in coffee combined with MCTs provides a synergistic effect on brain function.

Contains Beneficial Nutrients

  • Grass-fed butter has vitamins A, D, E, K2, and CLA. Grass-fed butter is higher in antioxidants like vitamin E compared to grain-fed.
  • Ghee made from butter contains butyrate and lauric acid which have antiviral, antifungal and anti-inflammatory effects in the body.
  • MCTs have antimicrobial and antifungal properties. Lauric acid in coconut oil is effective against harmful pathogens like candida.

May Protect Brain Health

  • Ketones may protect against neurodegenerative diseases like Alzheimer’s and dementia. MCTs improved cognition in Alzheimer’s patients in one study.
  • A study found MCTs increased good HDL cholesterol while lowering inflammatory markers in the blood. This could reduce risk of dementia.
  • The combination of caffeine and MCTs may protect against cognitive decline. More research is still needed in this area.

By adding butter or MCT oil to coffee, people can enjoy sustained energy, fat burning, and cognitive benefits supported by scientific studies. The ketones and healthy fats make this unconventional coffee drink worth trying.

How to Add Butter to Your Coffee

Adding butter or MCT oil to your coffee is simple with just a few key steps:


You’ll need grass-fed unsalted butter or ghee, and optionally coconut oil or MCT oil. Many recommend using grass-fed butter specifically as it has a better nutritional profile.


Brew coffee using your preferred method. A French press, pour over, or cold brew are common choices. Brew the coffee strong, using 2x the normal amount of grounds.


Pour the hot coffee into a high-speed blender like a Vitamix or Bulletproof Blender. Let coffee cool slightly before adding butter to prevent burning or separating.


Aim for 1-2 tbsp of butter or ghee and 1 tbsp of MCT oil per cup of coffee. Start with less if new to butter coffee.


Blend ingredients for 30-60 seconds until mixture becomes emulsified and frothy with a latte-like texture.


Store blended butter coffee in an airtight container in the fridge. The fat can separate, so shake or reblend before drinking.


Cinnamon, vanilla extract, cocoa powder, or collagen peptides can be added for flavor. Sweeteners like stevia may also be used.


If butter separates, use an immersion blender to re-emulsify. Reduce amount of fat if it causes digestive issues.

Properly preparing butter coffee ensures maximum emulsification so you get the full energy, cognitive, and health benefits. Experiment with different beans, fat ratios, and flavors to create your perfect cup.

Potential Concerns

While butter coffee may offer some benefits, there are a few potential downsides to consider:

High in Saturated Fat

Butter and coconut oil are high in saturated fat. This may negatively impact heart health, so moderation is key if at risk for heart disease.

Laxative Effect

High fat intake can cause digestive issues like diarrhea. Start with small amounts of butter or MCT oil to allow your body to adjust.

Intermittent Fasting

Technically breaks a fast, so limit intake if practicing intermittent fasting or time-restricted eating.

Calorie Density

Easy to consume excess calories if drinking multiple cups per day. Be mindful of overall calorie intake.
