What Does Bulletproof Coffee Do to the Body?

3 min read

Made popular by entrepreneur Dave Asprey in 2009, Bulletproof coffee is a unique beverage blending coffee with grass-fed butter or ghee and MCT oil. It is touted for its ability to provide sustained energy and enhanced focus, but what does Bulletproof coffee do to the body, and are all the claims backed by science?

Quick Summary

Bulletproof coffee, a high-fat drink, uses MCT oil and butter to produce ketones for energy, potentially boosting focus and curbing appetite. Effects on weight loss and cholesterol are debated.

Key Points

  • Sustained Energy: The combination of caffeine and fats slows energy release, preventing the typical caffeine crash and providing a steadier boost throughout the morning.

  • Ketone Production: MCT oil is quickly converted by the liver into ketones, which can serve as an alternative energy source for the brain and body, especially for those on a keto diet.

  • Appetite Suppression: The high-fat content promotes feelings of fullness, which can help reduce cravings and caloric intake throughout the day.

  • High Calories and Saturated Fat: Bulletproof coffee is high in calories and saturated fat, which can lead to weight gain or increased cholesterol if not accounted for in overall diet.

  • Not a Balanced Meal: As a breakfast replacement, it lacks essential nutrients like fiber, vitamins, and protein, potentially leading to deficiencies over time.

  • Mental Clarity: Many consumers report improved mental focus and clarity, attributing it to the brain's use of ketones for fuel.

What Is Bulletproof Coffee?

Bulletproof coffee is a blend of high-quality coffee with two tablespoons of grass-fed butter or ghee and one to two tablespoons of medium-chain triglyceride (MCT) oil. Unlike standard coffee, this high-fat, no-carb drink is popular in ketogenic and low-carb diets for providing energy and maintaining ketosis. The mixture is blended to a frothy texture.

The Science Behind the Effects

The body processes the fats in Bulletproof coffee differently than carbohydrates. Instead of glucose, the liver converts MCTs into ketones, an alternative fuel source for the brain and body. This metabolic shift can impact how a person feels. The saturated fats from butter and MCT oil are metabolized slowly, contributing to sustained energy and preventing energy crashes.

Potential Benefits for the Body

Provides Sustained Energy and Mental Focus

A key benefit is a steady energy boost without typical caffeine jitters. Fats slow caffeine absorption, extending its effects. Ketones from MCT oil also fuel the brain, which many users report leads to increased mental clarity and focus.

Promotes Satiety and May Aid Weight Management

The high-fat content increases feelings of fullness, reducing appetite and cravings. Some evidence suggests MCTs can boost metabolism and fat-burning, potentially aiding weight loss, though this is debated and dependent on overall calorie intake.

Supports Ketosis

For those on a ketogenic diet, Bulletproof coffee helps maintain ketosis by providing a zero-carb, high-fat energy source. It supports the body's fat-burning state without spiking blood sugar or insulin.

Supports Gut Health

Grass-fed butter contains butyrate, a fatty acid that can reduce inflammation and strengthen the gut lining. MCT oil also has antimicrobial properties that may help balance gut bacteria.

Potential Risks and Downsides

High in Calories and Saturated Fat

A significant concern is the high calorie count, ranging from 230 to 500 calories per cup, which can lead to weight gain if not used as a meal replacement. The high saturated fat content can also raise LDL cholesterol and increase heart disease risk for some individuals.

Nutritional Deficiencies

Replacing a balanced breakfast with Bulletproof coffee can lead to missing out on essential nutrients like fiber, protein, vitamins, and minerals. While butter offers some fat-soluble vitamins, it's not a substitute for a nutrient-dense meal.

Digestive Issues

High amounts of MCT oil can cause digestive discomfort like stomach pain, bloating, and diarrhea, especially for new consumers. Starting with a small amount of MCT oil and gradually increasing is recommended.

Bulletproof Coffee vs. Regular Black Coffee

Feature Bulletproof Coffee Regular Black Coffee
Calories High (approx. 230-500) Very low (under 5)
Fat Content Very high (saturated fat) Zero
Nutritional Profile Low (lacks fiber, protein, most vitamins) Contains antioxidants, low calories
Energy Source Fats (MCTs converted to ketones) and caffeine Caffeine primarily
Energy Duration Sustained and steady; less 'crash' Quicker boost, potentially followed by a crash
Satiety Effect High; helps curb appetite Low to none
Diet Compatibility Best for keto, paleo, or intermittent fasting Compatible with most diets

Is Bulletproof Coffee for Everyone?

Bulletproof coffee isn't suitable for everyone. Individuals with high cholesterol, heart problems, or certain gastrointestinal issues should consult a doctor before consuming it regularly. Pregnant or breastfeeding women should also be cautious. While occasional consumption may be fine for healthy individuals, daily replacement of a nutritious breakfast is not recommended. Long-term effects are not fully understood.

Conclusion

What Bulletproof coffee does to the body involves both benefits and drawbacks. It offers sustained energy, mental focus, and satiety, appealing to those on keto or intermittent fasting diets by using MCT oil for ketone production. However, it is high in calories and saturated fat, poses a risk of nutritional deficiencies if replacing meals, and can cause digestive issues. Its effects are individual and depend on diet, health, and goals. It is a potent drink, but its impact on a balanced diet should be considered.

Frequently Asked Questions

Bulletproof coffee may support weight loss by suppressing appetite and boosting metabolism due to MCT oil, which can help burn more calories. However, its high calorie count means it can also cause weight gain if not used as a meal replacement and managed within your daily caloric intake.

Due to its high saturated fat content from butter and MCT oil, Bulletproof coffee can potentially increase LDL ('bad') cholesterol levels in some individuals. Those with pre-existing cholesterol issues should consult a doctor before consuming it regularly.

No, it is not safe for everyone. Individuals with heart conditions, high cholesterol, certain gastrointestinal issues, or diabetes should be cautious. Pregnant and breastfeeding women are advised against it due to high caffeine and fat content.

This is debated within fasting communities. While it contains calories, it does not cause a significant insulin spike like carbs and sugar do. Some purists consider any caloric intake to break a fast, while others find it useful for extending their fasting window without breaking ketosis.

Common side effects include digestive issues like stomach pain, bloating, and diarrhea, especially when first introducing MCT oil. High caffeine intake can also cause jitters, anxiety, or insomnia in sensitive individuals.

Grass-fed butter is preferred because it contains more beneficial nutrients than butter from grain-fed cows. These include Omega-3 fatty acids, fat-soluble vitamins (A, D, E, K), and butyrate, which supports gut health.

It is best to start slowly. Use just a teaspoon of MCT oil and a smaller amount of butter initially to see how your body reacts. Gradually increase the amounts as your digestive system adjusts to the new fat intake.
