If you haven’t heard of this trend, butter in coffee is exactly what it sounds like: adding butter to your coffee.
I know what you’re thinking: “Butter? In coffee? What kind of a madman would ever do such a thing?”
Read on to find out.
Why do people put butter in coffee?
Most people who put butter in their coffee do it for the supposed health benefits.
There are many claims about its various benefits: diminishing hunger, boosting metabolism, increasing energy levels and more.
Regardless of why you’re putting the butter in your coffee, what most people trying the trend have in common is that they’ve been influenced by Dave Asprey, aka “The Bulletproof Coffee Guy.”
Asprey is a biohacker and author, who has written multiple books on health-related topics.
In 2009 he published a post on his blog describing how he would make coffee with grass-fed butter after hiking at high altitude. The idea was to get an extra boost from the caffeine and fat content of the beverage.
In 2014 Asprey came out with a book called The Bulletproof Diet: Lose Up to a Pound a Day, Reclaim Energy and Focus, Upgrade Your Life that extolled the virtues of putting butter in coffee as part of a diet plan.
The Bulletproof Diet includes tips on how to eat for optimal mental performance and physical health—which includes adding bulletproof upgrades (like butter) to your food and drink wherever possible.
Butter in coffee for Keto
Butter in coffee is also popular among those on the keto diet. If you’re not familiar with the keto diet, it’s a low-carb, high-fat eating plan. It’s intended to help you reach ketosis.
Ketosis is when your body starts burning stored fat as energy instead of carbs and sugar. When you’re in ketosis, it’s thought that your metabolism speeds up and can help with weight loss. Some people go on the keto diet for mental clarity and more control over their hunger levels too.
Since butter in coffee contains both fat and caffeine, it could help keep you fueled during intermittent fasting or a busy day on the keto diet.
What does it taste like?
With butter in your cup, you’ll notice a subtle nuttiness and creaminess that brings a depth of flavour as well as richness to your morning brew.
Depending on the type of butter you use, the taste will vary a bit.
Grass-fed butter adds a rich and slightly sweet taste while using non-grass-fed (regular) butter can leave a salty note.
How much butter to put in coffee
It’s recommended to start with about 1 tsp (4 g) of butter for a 10–12 ounce cup of coffee.
This is approximately the amount found in Bulletproof Coffee, which contains 1 tbsp (15 ml) MCT oil and 2 tbsp (28 g) grass-fed butter for an 8-ounce (240 ml) cup of coffee.
For Bulletproof Coffee, you can also use 2–3 tbsp MCT oil instead of or in addition to the grass-fed butter.
Many people combine both MCT oil and butter to reap the benefits of both.
And if you don’t have access to MCT oil, refined coconut oil is a great substitute.
The health benefits of butter in coffee
There are many promises attached to adding butter to coffee, or drinking bulletproof coffee, including benefits like increased energy levels and a more efficient metabolic system.
These effects have yet to be proven – Healthline
There’s no concrete scientific evidence that ingesting butter and MCT oil will improve your metabolism (unless you’re severely deficient in certain fats; in that case, consult a doctor before trying anything).
Can you use almond butter instead?
Almond butter is a great alternative for people who don’t do dairy or prefer to limit their saturated fat intake.
In addition to being rich in vitamin E, almond butter contains more calcium, magnesium and potassium than regular butter.
It also has less saturated fat, though you won’t get the same cholesterol-lowering benefits that come with consuming grass-fed butter.
