There is a current trend for ‘Bullet Proof Coffee’ which is used to boost endurance performance, in this post, we’ll explain the basic thinking behind the concept and how it can help you when training for endurance based events such as marathon running, cycling and long distance triathlon events.
Why Bullet Proof Coffee?
It’s something we’ve discussed many times before, if you can increase your fat burning during exercise, you will save glycogen (carbohydrate) and therefore exercise for longer. People who use glycogen at a high rate will run out much more quickly, so shifting your metabolism to use fat as your main source of energy is of great benefit.
What is Bullet Proof Coffee?
The subject can become a little over complicated, but in simple terms, it’s ground coffee with added MCT oil and butter. The perfectionists will argue that you need a specific high quality coffee bean freshly ground, but I’m sure you can start with general filter coffee powder and progress from there! The term MCT oil refers to ‘medium chain triglycerides’ which are a specific type of fat which is known to be fantastic for energy. MCT is found in coconut, so MCT oil is generally derived from coconut with the flavour removed. The other ingredient is butter, preferably organic and grass fed to be high quality, don’t use ‘Flora’ or ‘I can’t believe it’s not butter’ it’s really not the same. Full fat, organic, grass fed butter might sound a little strange as it’s high in saturated fat. However, saturated fat is one of your main fuels and critical for endurance performance.
Those who know a bit about nutrition trends will be familiar with the above info, those who are not familiar with nutrition trends might be thinking ‘I thought saturated fats were the bad one’s?’ It turns out they were wrong, who’d have thought it? it’s a long explanation so probably easiest if you just go with it…
Make your coffee, add 1-2 tbs of MCT oil and 1-2 tbs of butter. Put it all in the blender and whip it up until you have a nice froth on the top. You can pour boiling water into your blender to keep it hot, then empty it just before the coffee goes in to stop the coffee cooling. Fat & oil don’t dissolve in water so it floats in the top.
You alternative option (the fanatics will not like this) is to use MCT powder. It works a bit like coffee mate, add a heaped teaspoon to your cup then add a small amount of coffee. Give it a good stir and whip to get the lumps out, then add the rest of the coffee. MCT powder tastes quite creamy (not of coconut) and you might find it more palatable than oil and butter floating on the surface, although I’d encourage you to try to original recipe also!
When should I drink it?
Before you go training, most people will generally opt for one of the following:
1. High carb breakfast
2. No breakfast
3. High fat breakfast
All 3 are viable, but it really depends upon the athlete and the type of session you are about to take part in. We will discuss this in a lot more detail next Tuesday.
Eating no breakfast (fasting) is a common method for encouraging the body to burn more fat, but actually taking a high fat breakfast (in this case a bullet proof coffee), might enhance fat usage even greater, by increasing the amounts of fats circulating in the blood.
IMPORTANT: It should be used for endurance sessions (long and slow) and works perfectly if you’re following a Maff formula or similar (as per last week’s blog). Each person will differ, but eating no breakfast and drinking a bullet proof coffee would work perfectly for:
Endurance runs of 1-2 hours
Endurance cycles of 2-3 hours
The timescales will very much depend upon the experience and fitness of the athlete. If you are very well trained, you may well be able to do more on a single drink, but these are average timescales. You should not take any breakfast beforehand and you should not eat sports products or ingest any other form of energy during the run or ride. You should also ride at the correct intensity (as per Maff or similar).
What to do next?
Buy some filter coffee, or some beans and a grinder. Google MCT oil or MCT powder and purchase some online, then get some grass fed organic butter. If you don’t have a blender, don’t worry, just give it a good whisk with a fork!! Drink the coffee 30 minutes before exercise.
