Day 24: Bulletproof Coffee

Breakfast: BP Coffee
Lunch: Chicken Salad and ½ avocado
Dinner: Burger with tomatoes and pesto and ½ avocado

I had my dinner at 5.30pm. I was planning on having another meal when I got home, but I was late and I was too lazy to cook. I didn’t want to go to bed on a full stomach either.


Until now I said that I’ve been having a coffee for breakfast. That’s not entirely true. I’ve actually been having a “Bulletproof” coffee (BP Coffee). The word “Bulletproof” is just branding; it doesn’t describe the physical characteristics of the coffee (to my flatmate’s genuine disappointment).

BP Coffee is a regular black coffee (Americano/long black) mixed with about 25g of grass-fed butter (Kerrygold) and Medium Chain Triglyceride (MCT) oil in a blender (bear with me!). Once blended, BP Coffee is creamy with a frothy head, much like a latte. Some people use 50-100g of butter. I’ve tried 50g before but the butter taste was too strong for me. It was kinda sickening tbh. I’ll be sticking to 20-30g in future.

I mentioned the benefits of butter yesterday. MCT oil is made from coconut oil (also palm oil). It’s a clear liquid and it doesn’t have a taste. MCTs are triglycerides which means they’re fats. The longer chain triglycerides (those with more than 12 carbon atoms) are removed. These triglycerides are harder for the body to process, so they are more likely to be stored as fat. Unlike other fats, MCTs don’t need to be broken down with bile salts, so they go straight into the blood stream.

The main benefits of MCTs for me are that they improve blood sugar and appetite regulation, and enhance ketone production. In other words, it helps me to use stored body fat for fuel. MCTs have also been used to treat digestive issues (IBS, Crohn’s etc), seizures, and Alzheimer’s.

I like doing as little as possible in the morning and I prefer not to eat breakfast, much less wash a load of dishes.  I drink BP Coffee because the fat in the butter keeps the hunger pangs away until lunch, while the MCTs help me to use stored fat as fuel. BP Coffee doesn’t have much protein in it, so drinking it won’t take you out of autophagy.

Some people are evangelical about Bulletproof Coffee. I get tired of the marketing but it’s a good product. I’m not sure whether the MCT Oil has any great benefits, but coffee mixed with butter is an easy start to the day for me.

The idea originally came from the Bulletproof Exec (Dave Asprey).  You can find everything you need to know about it here. The coffee beans he sells are expensive and probably not essential. You can also get more on the benefits of MCTs on his site but he sells MCTs so you can take it with a pinch of salt.
