What is Butter Coffee and Where Did it Come From?
Butter coffee, famously branded as Bulletproof Coffee, is a hot beverage made by blending brewed coffee with unsalted, grass-fed butter and medium-chain triglyceride (MCT) oil. The result is a creamy, frothy drink with a latte-like consistency. The modern iteration was popularized by entrepreneur Dave Asprey after he was inspired by traditional Tibetan yak butter tea. The core idea is to create a high-fat, low-carb drink that provides sustained energy and promotes feelings of fullness.
The Allure of Bulletproof Coffee
The primary draw of butter coffee, especially for those on a ketogenic or low-carb diet, is its high fat content. In a ketogenic state, the body burns fat for fuel instead of carbohydrates. The MCT oil in particular is rapidly converted into ketones by the liver, providing a quick source of energy for both the body and the brain. Proponents often use this drink as a breakfast replacement to kickstart their day with steady energy, avoiding the blood sugar spikes and crashes associated with carbohydrate-heavy meals.
The Potential Benefits of Adding Butter to Coffee
Advocates of butter coffee point to several potential health advantages. These benefits, however, are largely tied to the properties of the individual ingredients rather than the combination itself, and more research is needed to substantiate many of the claims.
- Sustained Energy and Focus: The combination of caffeine and healthy fats is thought to provide a more prolonged and stable energy release compared to regular coffee. The fat slows the absorption of caffeine, reducing the jitters and crash some experience. The ketones from MCT oil can also serve as an alternative fuel for the brain, potentially improving mental clarity and cognitive function.
- Promotes Fullness: The high fat content in butter coffee, especially the MCT oil, is highly satiating. This can suppress appetite and reduce food cravings throughout the morning, potentially leading to lower overall calorie intake. This satiating effect is a key reason many use it to aid in weight management and intermittent fasting.
- Supports Ketogenic Diets: For individuals following a ketogenic diet, consuming high amounts of healthy fats is essential to maintain ketosis. Butter coffee is an easy and delicious way to increase daily fat intake and boost ketone production.
- Nutrient Boost (from grass-fed butter): Grass-fed butter, a key component of many butter coffee recipes, is a better source of certain nutrients than conventional butter. It contains higher levels of anti-inflammatory omega-3 fatty acids, conjugated linoleic acid (CLA), and fat-soluble vitamins like A and K2.
Comparison: Butter Coffee vs. Regular Coffee
| Feature | Regular Black Coffee | Butter Coffee (with MCT oil) | 
|---|---|---|
| Calories | Very low (approx. 5 cal) | High (approx. 250-400 cal) | 
| Energy Source | Primary caffeine stimulation | Slower caffeine release + energy from fats (ketones) | 
| Satiety | Low | High; promotes feeling of fullness | 
| Nutrients | Rich in antioxidants | Lacks essential protein, fiber, and some vitamins | 
| Dietary Context | Can be enjoyed by anyone | Best suited for ketogenic or low-carb diets | 
| Potential Crash | Possible post-caffeine crash | Less likely due to slow-release energy | 
The Potential Downsides and Risks
Despite its benefits, butter coffee comes with significant drawbacks and is not suitable for everyone. It's important to consider the risks before making it a routine part of your diet.
- High in Saturated Fat: A single cup of butter coffee can contain more than the American Heart Association's recommended daily limit for saturated fat. While the effects of saturated fat are still debated, high intake is often linked to increased LDL ('bad') cholesterol, which can raise the risk of heart disease for some individuals.
- Nutrient Displacement: Drinking butter coffee as a meal replacement, particularly for breakfast, means you are missing out on essential nutrients like protein, fiber, vitamins, and minerals that a balanced meal would provide. This can lead to nutritional deficiencies if not properly managed through the rest of your diet.
- Risk of Weight Gain: While marketed for weight loss, the high-calorie content means that adding butter coffee to your existing diet without making other caloric adjustments can easily lead to weight gain. It's crucial to account for the calories from the fats.
- Digestive Issues: The high-fat content, especially the concentrated MCT oil, can cause digestive distress, including bloating, stomach aches, and diarrhea, particularly for those not accustomed to a high-fat diet. It is recommended to start with a small amount of MCT oil to test tolerance.
- Unproven Claims: Many of the more extravagant claims about increased IQ or dramatic fat loss are not backed by solid scientific evidence. The benefits that are observed are often attributed to the individual ingredients rather than the specific combination.
Conclusion: Should You Be Drinking Butter Coffee?
For those on a ketogenic diet, butter coffee can be a useful tool to help achieve and maintain ketosis, provide satiety, and deliver a clean energy boost. The best results are seen when high-quality, grass-fed butter and MCT oil are used. For the average person, however, the high saturated fat and calorie content, combined with its lack of essential nutrients, make it a less-than-ideal breakfast replacement. Before adding butter coffee to your daily routine, it is wise to consult a healthcare professional, especially if you have existing heart or cholesterol concerns. Ultimately, there is no magic bullet for optimal health; a balanced diet rich in whole foods remains the most beneficial approach for most people.

How to Make a DIY Butter Coffee
For those who decide to try it, a basic recipe involves blending hot coffee with fat until it's frothy. Ensure you use a blender, as simply stirring will leave an oily film on top of your coffee.
- Brew 1 cup (8–12 ounces) of high-quality coffee.
- Add 1–2 tablespoons of unsalted grass-fed butter or ghee to the blender.
- Mix in 1–2 teaspoons of MCT or coconut oil.
- Blend for 20-30 seconds until the liquid is creamy and emulsified.
How to Enjoy Butter Coffee Safely
If you choose to incorporate butter coffee into your diet, consider these tips for a healthier approach:
- Do not replace nutritious meals. Think of it as a supplemental fat source or an occasional energy boost, not a substitute for a balanced meal.
- Mind your calories. Factor the high-calorie content into your daily intake to avoid unintentional weight gain.
- Start with small amounts. Begin with a teaspoon of MCT oil to let your digestive system adjust before increasing the amount.
- Use high-quality ingredients. Opt for grass-fed butter and pure MCT oil, rather than coconut oil, for the most potent ketone-boosting effect.
