Have you heard of bulletproof coffee, the latest trend in the nutrition world? Putting butter in your coffee has actually become a thing. What exactly is it and why would anyone do that?-We’re answering all your questions today.

To make bulletproof coffee you brew your regular morning cup and finish it off by adding two tablespoons of butter, one tablespoon of medium chain triglyceride (MCT) oil, and blending the mixture all together until frothy.

Advocates of the trend say you should skip breakfast and only have coffee to reap the maximum ‘benefits’. That is, not eating for the first four hours after you wake up. So not only are you skipping what is considered the most important meal of your day, but you’re swapping it out with a highly saturated, fatty, caffeinated drink instead. Just from this one morning drink, you would be consuming 140% of your recommended intake of saturated fat before you’ve even had a bite of any actual food. I don’t know about you, but that doesn’t sound like a good idea to us.

We’ll be honest, mixing coffee and butter does make your coffee extremely creamy and tasty. If you choose to add butter to your coffee because you simply like the taste of it, then that is absolutely up to you. The problem here is doing something thinking it’s beneficial to your body, when in fact it’s doing a lot more harm than good. The claims regarding the benefits of drinking this coffee concoction are what I find particularly frustrating. The founder of the bulletproof coffee trend, Dave Asprey, claims that starting your day off with bulletproof coffee maximizes fat loss and acts as the perfect brain fuel. He even goes as far as saying that the drink is healthier for your body than having a bowl of hearty oatmeal. None of these claims are scientifically backed or certified in any way.

Eating nothing but fat and caffeine in the morning stresses your body out, you might feel full for an hour or so, but once the hunger pangs kick in and you get that post caffeine crash, you will be much more likely to raid the sweets drawer and binge by eating anything that’s in front of you. An additional problem is that you probably won’t be able to digest whatever you eat afterwards very well because your stomach is too busy digesting the huge amounts of fat you bombarded it with first thing in the morning. Slower metabolism, an upset tummy, and blood sugar spikes are what you are looking at.

Moral of the story, don’t trust everything you read on the internet. Bulletproof coffee is an extreme fad nutrition trend full of misinformation. Coffee and butter in moderation are totally fine (read more about the benefits of coffee here), just not together in excessive amounts every morning. There are tastier ways to drink coffee and better ways to be healthy.
