Is Butter Coffee Here To Stay Or Just A Trend? A Nutrition Historian Weighs In

Butter coffee is typically made by adding a few tablespoons of butter and medium-chain triglycerides (MCT) oil to coffee. Beyond bringing a rich flavor and creamy consistency to your cup of coffee, it might also offer a few health benefits.

In fact, fans of butter coffee swear by its ability to boost energy levels, rev up weight loss, and fine-tune focus. It’s become particularly popular among keto dieters and those practicing intermittent fasting, who claim that it can help speed up the transition into ketosis1, a metabolic state that uses fat for fuel instead of sugar.

“Although blending butter or oil into one’s morning cup of coffee seems like a recent trend, people have been adding animal fats to their coffee for well over one thousand years,” Hannah Cutting-Jones, Ph.D., a food historian and the Director of Food Studies at the University of Oregon, tells mindbodygreen.

“Sometime between 575-850 CE, Ethiopians consumed coffee beans crushed up with animal fat (probably ghee, or clarified butter) to provide them with energy, stamina, and courage,” Cutting-Jones adds.

According to Cutting-Jones, the practice is still pretty common in many parts of the world, including Tibet and certain areas in India, Singapore, and Vietnam.

Its recent resurgence may be thanks to American entrepreneur David Asprey, who visited Tibet in 2009 and “came home a believer in the physical and mental benefits of drinking coffee with yak butter,” Cutting-Jones says. Once he was back in the United States, Asprey developed his recipe for Bulletproof coffee made with coffee, MCT oil, and butter, launching the trend throughout the Western world.

Summary

Some people swear by butter coffee to boost energy, enhance focus, and lose weight. While entrepreneur David Asprey popularized the beverage in the U.S. years ago, people around the world have actually been drinking some version of it for centuries.

Adding butter to your coffee is often touted as an easy way to increase the flavor and richness of coffee while also bumping up the fat content of your brew.

In fact, each tablespoon of butter packs in about 11.5 grams of fat2, 55% of which is saturated fat. Butter is also high in calories and vitamin A, an essential nutrient needed to keep your eyes healthy and enhance your immune system3. In butter coffee, butter is usually paired with MCT oil4, a type of saturated fat derived from coconut oil.

While there haven’t been many studies on butter coffee specifically, its individual ingredients have been linked to some health benefits. Here, we take a closer look at what the science says. 

1.

It can keep you feeling full.

Science showcase

One small study conducted in 2021 compared the effects of black coffee with Bulletproof coffee, which was made with 10 ounces of coffee and 1 tablespoon each of MCT oil and grass-fed ghee. In the study, six healthy young adults completed a task to measure cognitive performance and then filled out a questionnaire to measure hunger/fullness, cognitive arousal, and digestive distress. Then, they consumed one of the two beverages and repeated the tasks again after 60 and 170 minutes. A week later, they repeated the study using the other beverage and the results were compared.Researchers found that Bulletproof coffee didn’t offer much of an edge over black coffee in terms of cognitive function. However, participants did report increased feelings of fullness and decrased prospective food consumption (aka the amount of food they believe they could eat) after drinking Bulletproof coffee.

It may help boost brain function.

While there’s not a lot of research on butter coffee itself, plenty of studies have found that caffeine can help give brain function a boost. For instance, several studies have found that caffeine may help enhance attention8, increase processing speed9, and improve both short-term and long-term memory.

Poff notes that MCTs are also naturally ketogenic10, meaning that they are converted into ketones (a type of chemical produced in the liver), even if you’re not cutting carbs. “Many pre-clinical studies have shown that both MCTs and ketones can support neuronal health and brain function, especially in conditions where it may be limited, such as in cognitive impairment,” she says.

In fact, research shows that MCTs could slow the progression of Alzheimer’s disease11 and enhance cognitive performance12 in young adults. 

On the other hand, not all research has been quite as promising and studies in humans are still pretty scant. Furthermore, the 2021 study6 mentioned earlier showed that coffee combined with MCT oil and ghee offered no additional benefits over regular coffee for cognitive performance.

It could enhance energy levels.

In theory, some of the specific ingredients used to make butter coffee could help ramp up energy levels and fend off fatigue.

MCTs13, for instance, are absorbed and metabolized differently than other types of fat, providing a quick burst of energy for the body, according to Poff. Meanwhile, the caffeine found in butter coffee (and regular coffee) has been shown to boost wakefulness14 and increase alertness, making it a popular choice as a mid-morning pick-me-up.

Still, more research is needed to evaluate how caffeine and MCTs may affect energy levels when combined.

It could contribute to weight gain.

The total calorie count for your cup of butter coffee can vary depending on several factors, including how much butter and MCT oil you add. Regardless, there’s no denying that it’s definitely not a low-calorie beverage—even with just 1 tablespoon each of butter2 and MCT oil15, a single cup contains 224 calories.

While there is some evidence that its high fat content could suppress hunger and keep you feeling full between meals, the extra calories can stack up pretty quickly, especially if you’re drinking a cup or two each day. If you’re not making any other changes to your diet to balance out your calorie intake, this could lead to weight gain over time.

It might cause digestive distress.

It’s not a great fit for those with heart disease or high cholesterol levels.

Butter is high in cholesterol, with nearly 33 milligrams2 packed into each tablespoon. For the most part, researchers agree that dietary cholesterol has little to no impact on cholesterol levels17 in your blood. However, about one-third of the population is considered “cholesterol hyper-responders,” meaning that they may be more sensitive to the effects of cholesterol found in foods.

Therefore, if you have a history of heart disease or have high cholesterol levels, be sure to check in with your doctor before making butter coffee a staple in your daily diet.

Adding a scoop of butter or MCT oil to your morning cup of coffee is a popular choice during fasting. Because butter coffee doesn’t contain any carbohydrates, it’s unlikely to spike your blood sugar levels. Plus, its high fat content can help keep you feeling full until your next meal.

However, note that coffee may slightly increase insulin production20, meaning it might not be suitable for a super strict fast. To minimize its effects on blood sugar levels, be sure to skip the sugar packets, flavored syrups, or other sweeteners to keep it completely carb-free.

According to Cutting-Jones, people have been enjoying the rich flavor and health benefits of butter coffee for well over a thousand years, and it’s still a common practice in many parts of the globe. “Tibetan farmers still drink a fermented black tea with yak butter, and in parts of India, Vietnam, and Singapore, butter coffee (or tea) is consumed regularly,” she says.

However, whether or not butter coffee has staying power past the current high-fat keto craze remains up for debate. “I think Bulletproof coffee is probably a fad,” says Cutting-Jones. “But to those who enjoy the rich taste of butter in their coffee without expecting it to be a panacea for all their health issues, I raise a mug!”

Some people opt to add coconut oil to their coffee in lieu of butter or MCT oil.

Coconut oil is high in saturated fats and contains MCTs, so it may offer some of the same health benefits as butter coffee. However, unlike MCT oil, coconut oil21 also contains some long-chain triglycerides, which aren’t associated with the same health-promoting properties. Plus, keep in mind that it can be a bit harder to blend and could add a subtle, coconut-like flavor to your coffee.

Milk and cream are also common coffee additions used to bring a touch of sweetness to your brew.

However, unlike butter coffee, coffee made with milk or cream can increase your intake of carbs, especially if you’re adding more than a splash or so. These varieties of coffee can increase blood sugar levels slightly, meaning they may not be a good fit if you’re fasting or on a strict keto diet.

Though butter coffee has recently become a hot trend in health and wellness circles, it’s actually been around for quite some time. While some research suggests that it could increase focus, enhance energy levels, and help hold you over until lunch, it can also have some side effects and may not be the best choice for everyone.

If butter coffee isn’t your style, try experimenting with other mix-ins like collagen, turmeric, or cinnamon. Alternatively, give other healthy drinks like green tea, black tea, or matcha a shot instead.
