Is Adding Butter to Your Coffee Actually Good For You?

The Bulletproof coffee trend promises more energy, better focus, weight loss and improved health — but does it work?

A new craze is seeing coffee-drinkers blending their morning brew with up to 60 grams of butter and oil, in a bid to boost energy levels and promote weight loss.

After hearing the @947Highveld morning team chatting about Bullet Coffee I decided to make my own!

1 cup of good quality filtered coffee coming up …

bullet coffee

Add 1-2 Tbsp butter (unsalted butter) and 1-1-2 Tbsp coconut oil …


You have to beat it with an electric beater (or Thermomix in my case) to get it to blend …



The outcome? Well it did not taste as bad as I imagined. It was very rich though and my stomach felt unsettled for a while after sipping the high fat beverage. I think I am going to stick to my regular morning java. Butter and oil free.

The pros of having bullet coffee:

  • The caffeine will give you a boost and may increase mental alertness.
  • The fat content will make the drink more filling so stave off hunger.

The cons … (which outweigh the pros!)

  • Replacing breakfast on a regular basis with bullet coffee will certainly make it harder to reach your nutrient and fibre requirements.
  • 2 TBS butter and 2 TBS MCT oil provides a whopping 1200 kJ (300 calories) so it has to replace some food or another caloric beverage. If not, you could gain an extra 10 kg each year by having a cup per day!
  • It would also not be a good idea for people who have digestive problems to start their day with a caffeine jolt and so much fat – this could cause some serious digestive discomfort.

Some of the claims made by Bullet Coffee fans are false and unsubstantiated:

“Improve brain performance by feeding your brain with ketones”

  • This would only be true if the coffee drinker was consuming a very low carbohydrate diet overall (less than 30 g carbohydrate per day).

“Just enjoy coffee without feeling anxious or jittery.”

  •  If you are caffeine sensitive then the caffeine in the coffee would still have an effect on your body.

Dave Asprey, the Bulletproof Exec, is the mastermind behind the creation of the worldwide health craze of Bulletproof® coffee. Dave says: “After one drink of Bulletproof coffee, you’ll never be tempted to eat fat-free, insulin-raising, fat-storing toast and oatmeal breakfasts again!”

I’m not so sure that replacing a balanced breakfast (one providing fibre and high nutrient value and lean protein) with coffee beans and saturated fat is a sustainable and longevity-promoting strategy. Perhaps for that odd cold morning when you’re on the run, but not as a regular habit.  The bottom line: If you’re trying to cut kilojoules or saturated fat, Bulletproof Coffee probably isn’t the brew for you. As part of a balanced eating plan, it does however have more health benefits than many of the refined pastries or sugar laden cereals you may munch for morning sustenance.
