A little butter in your coffee and your energy level rises and the pounds fall away? The so-called bulletproof coffee is said to be an energy booster and at the same time boost your metabolism, making you fitter and slimmer at the same time. Years ago, the American Dave Asprey caused a real hype with his greasy coffee - now the trend has been revived. Rightly so?
Asprey is considered the inventor of “Bulletproof Coffee”. He is said to have acquired a taste for it during a trip in the Himalayas. After the entrepreneur drank a traditional tea made with butter from yak milk, it immediately had an invigorating effect on his body and mind; he felt fitter and more concentrated. Asprey took the enthusiasm home with him, where he developed “Bulletproof Coffee” based on yak tea.
The special coffee variant is advertised as being particularly healthy thanks to additional omega-3 fatty acids, vitamin A and butyric acid, among other things. Omega-3 fatty acids can lower blood pressure and have an anti-inflammatory effect, vitamin A is an antioxidant and butyric acid supports the health of the intestinal mucosa. MCT oil encourages the body to use fat as an energy source instead of glucose, which is said to have the effect of providing energy on the one hand and stimulating fat burning on the other.
But is that true? The positive effect of “Bulletproof Coffee” is controversial – especially when consumed excessively. If too many saturated fatty acids are consumed, they can have a negative effect on cholesterol levels and even increase the risk of cardiovascular disease. The butter and oil make the coffee a calorie bomb. The source of inspiration, yak tea, is primarily used as an additional source of calories by people in the mountains who are stressed by life at altitude and strenuous work.
People who move little and perhaps work while sitting use the ingredients differently. The likelihood of losing weight through the drink without also changing the rest of your diet is therefore considered to be low. However, due to the high fat content, the caffeine lasts longer. People who use butter coffee as a supplement to a type of fasting diet, such as those who follow a ketogenic diet and therefore primarily consume fats and proteins, but largely avoid carbohydrates, report positive effects.
250 ml freshly brewed coffee1 tbsp butter (unsalted)1 tsp MCT OIL (concentrated coconut oil)If necessary: some cinnamon and/or honey
Brew coffee, add butter and oil and, ideally, mix with a hand blender until a creamy, homogeneous liquid is formed. The coffee takes on a light color and develops a head of foam. If you like, you can add cinnamon and/or honey and mix briefly again.
Tip: Nutty and chocolaty coffees taste better when combined with butter and oil than fruity ones.
