Why are people putting oil in coffee for health and energy?

4 min read

Over 2 billion cups of coffee are consumed daily, and a growing number of people are adding a surprising ingredient: oil. The trend of putting oil in coffee, popularized by 'Bulletproof Coffee' and more recently by products like Starbucks' Oleato, is driven by a desire for enhanced energy, satiety, and cognitive function.

Quick Summary

The practice of adding oils like MCT, coconut, or olive oil to coffee is primarily for health benefits, such as sustaining energy, promoting ketosis, and improving mental focus. This high-fat brew helps slow caffeine absorption and increases satiety, making it popular within the keto and wellness communities. However, high caloric content and potential digestive issues are important considerations.

Key Points

  • Sustained Energy: Fats in coffee slow caffeine absorption, providing a smoother, longer-lasting energy boost without the typical crash.

  • Improved Mental Focus: Oils like MCT are rapidly converted into ketones, which act as a quick and efficient fuel source for the brain.

  • Supports Keto and Low-Carb Diets: Adding fat to coffee is a cornerstone of ketogenic diets, helping promote ketosis and provide a caloric, non-carb fuel source.

  • Increased Satiety: The healthy fats in oils help you feel fuller for longer, reducing cravings and appetite between meals.

  • High in Nutrients: Oils like extra virgin olive oil and grass-fed butter contain beneficial antioxidants and vitamins, adding nutritional value.

  • Enhanced Texture: Blending oil into hot coffee creates a creamy, frothy texture similar to a latte, without the need for dairy creamers.

  • Potential Digestive Issues: Starting with too much oil can cause digestive discomfort; beginners should start with a small amount.

  • Caloric Density: Be mindful of the high calorie count from adding oil, especially if you have weight loss goals.

The Rise of Oiled Coffee: More Than a Trend

The practice of adding fats to coffee isn't new, but it gained significant mainstream attention with the rise of the ketogenic diet and 'Bulletproof Coffee'. Initially promoted as a performance-enhancing breakfast replacement, this high-fat coffee promised sustained energy and mental clarity without the jitters or crash associated with a typical caffeine high. Fast-forward to today, and the trend has broadened, with everything from MCT oil to olive oil finding its way into morning brews.

The Science Behind Adding Oil

The fundamental reason for adding oil to coffee lies in the way our bodies process fats and caffeine. When fats are consumed with coffee, they slow down the absorption of caffeine. This results in a more gradual and prolonged energy release, helping to avoid the sudden spikes and subsequent crashes that many experience from black coffee or coffee with sugar. Additionally, for those on low-carb or ketogenic diets, these fats provide a quick and efficient source of energy in the form of ketones, which the body produces when converting fat for fuel.

Popular Oils and Their Benefits

MCT Oil

Medium-Chain Triglyceride (MCT) oil is one of the most popular choices for oiled coffee, primarily because it is metabolized differently than other fats. It is rapidly converted into ketones, providing a fast and efficient energy source for both the body and the brain. This can lead to improved mental focus, sustained energy levels, and enhanced fat burning.

Coconut Oil

Coconut oil is a natural source of MCTs and is a common alternative to pure MCT oil. It offers similar benefits, such as boosting metabolism and providing sustained energy. It can also add a subtle flavor and creamy texture to the coffee when blended properly.

Olive Oil

More recently, olive oil has entered the coffee scene, notably with Starbucks introducing its 'Oleato' line. Proponents cite its heart-healthy monounsaturated fats and high antioxidant content. Like other oils, it adds a smooth, velvety texture and can help extend the energy from the caffeine, though its flavor profile is more distinct and can be an acquired taste.

Potential Downsides and How to Address Them

While the benefits are appealing, adding oil to coffee is not without its considerations. The primary concerns include the high caloric density of oil and potential digestive issues.

Digestive Concerns

For those not accustomed to a high-fat diet, a tablespoon of oil in coffee can sometimes cause digestive discomfort, including bloating, gas, or diarrhea. The key is to start with a small amount (e.g., one teaspoon) and gradually increase as your body adjusts.

Caloric Density

A single tablespoon of olive or coconut oil contains over 100 calories. While beneficial for energy, this can quickly increase your daily caloric intake. If weight loss is a goal, it's important to account for these extra calories, especially if the oiled coffee is replacing a full meal.

How to Create the Perfect Oiled Coffee

To avoid a greasy mess and ensure the oil is properly emulsified, blending is crucial. Using a regular blender, immersion blender, or a milk frother is essential for creating a creamy, uniform texture rather than a separated layer of oil on top. Adding other ingredients like cinnamon or honey can also enhance the flavor and provide additional benefits.

Energy Boost Quick and sustained due to rapid ketone production Moderate and sustained; good source of MCTs Moderate; slows caffeine absorption for steady energy
Flavor Flavorless, which makes it highly versatile Subtle tropical or nutty flavor Distinct, sometimes peppery, flavor; can be strong
Texture Does not add texture unless blended; makes coffee very creamy Adds a creamy, smooth texture when emulsified Adds a velvety, lush texture when blended
Key Benefits Rapid ketone production, enhanced cognitive function Natural MCT source, metabolism boost Heart-healthy fats, high in antioxidants
Cost Generally more expensive than coconut oil More affordable than pure MCT oil Varies depending on quality; extra virgin is recommended
Main Drawback Can cause digestive issues if too much is used High saturated fat content (though healthy fats) Strong flavor might not appeal to everyone

The Rise of Oiled Coffee and the Modern Wellness Movement

The surge in popularity of adding oil to coffee aligns with a broader wellness movement that emphasizes biohacking, optimizing nutrition, and following specific dietary protocols like keto. As consumers become more conscious of how ingredients impact their bodies, the idea of turning a simple morning ritual into a functional health drink has gained serious traction. From high-performance athletes to everyday individuals looking for a productivity boost, oiled coffee represents a tangible way to actively manage energy and focus. For many, it replaces a carb-heavy breakfast, offering a sense of fullness and preventing mid-morning hunger pangs. This shift reflects a move away from simple calorie counting and toward a more nuanced understanding of macronutrient timing and composition for fueling the body and mind effectively. The cultural embrace of this trend was cemented when major coffee brands started incorporating it into their menus, making it accessible to a wider audience.
