There’s a lot of hype lately about the most recent coffee trend. Take your morning cup of joe, add two tablespoons of butter and some oil, and call it Bulletproof Coffee. No doubt it’s an interesting flavor, but it’s the claims of increased energy and weight loss that seem to be giving this morning jolt traction.

It’s not just any butter and coffee. Those supporting this idea say it has to be unsalted, grass-fed butter and medium-chain triglyceride oil (MCT) added to low-toxicity coffee beans. But can a mixture like that really live up to what proponents are saying?
What happens to butter in your body
There’s no real research into whether butter-spiked coffee is good for you, but we do know some things about how butter affects your digestion.
According to existing research, fat in butter contains glycosphingolipids, fatty acids that ward off gastrointestinal tract infections, especially in very young children and older adults.
Its omega-3 and omega-6 fats also slow down your body’s metabolism of caffeine, so you hold on to energy longer and avoid the crash that comes when the stimulant wears off.
More about MCT
MCT, most commonly found in coconut oil, is also good for our bodies and brains. When it comes to our bodies, we don’t store MCT in our adipose tissue, the fat around and inside our muscles, like the other dietary fats we eat.
Most of those fats are long-chain triglycerides, but MCTs are shorter. They travel directly to the liver where they’re processed into powerful energy particles called ketone bodies.
In addition, if your brain loses the ability to break down its primary fuel source, glucose, due to cognitive impairment or some other disorder, it can use ketone bodies as an excellent, alternative source. Research shows that people with cognitive impairment who ingest MCT experience an almost immediate improvement in mental function.
So do the health benefits of butter and MCT mean you should add them to your morning coffee? To begin with, if you don’t already drink coffee, I don’t recommend you start. If you do, though, I still don’t endorse your adding butter and oil to it, and I have no plans to do it either.
Healthy fats and oils do have a place in our daily diets, but I’m not convinced that enhancing our coffee with them is the best way to incorporate them.
