Butter coffee is a wonderful addition to any Keto diet but it only works if you put in the work. It's basically a meal replacement, so, if you're just adding it to your breakfast, don't expect good results. The idea is to drink this in place of your breakfast and lunch to help your body get into and stay in ketogenesis/ketosis. Then, at dinner time, be sure you're still keeping the carbs low to none.
Butter coffee is a rich, thick, creamy drink that is delicious if it's your thing. It can be sweetened with Splenda (or a knock-off brand, just make sure it's 0 carb,) or your favorite 0 carb sweetener, but I like the taste of coffee, so, leave mine as is.
You will need a personal blender*
Your choice of coffee**
1-2 Tablespoons of grass-fed, natural butter***
1-2 Tablespoons of coconut oil or MCT oil****
This is real simple - While your coffee is brewing, slice off 1-2 tablespoons of your butter and add it with the 1-2 tablespoons of coconut oil to your blender. Pour the coffee over the butter and oil, seal it up (each blender's a bit different, just follow the instructions included with yours,) and blend for at least 30 seconds to make sure it all mixes well.
If it's too hot, add a cube or two of ice but be cautious not to add too much as cooling it off too much can cause the butter to re-solidify and you don't want that.
Furthermore, if you choose to add a sweetener, I find it best to add before blending as what better way to stir it in?
It's best to start with 1 tablespoon each butter and coconut oil as they are rich, creamy, heavy fats and some don't care for the texture that results. If you can take it, or in fact like it, stick with two each as this will help keep you full and satiated throughout the day.
If you feel you need a bit more sustenance, I add 1 raw, washed egg before blending (out of the shell, of course, but always wash the shell first)
* Think Magic Bullet or similar devices, though my $10 Mainstays blender works wonderfully, albeit it's louder than sin - And that link is just for your convenience, I have no referral program or anything and get nothing for you clicking it.
** You can brew a pot, single serve Kuerig style, individual glass via French Press, it doesn't matter - just pick a coffee you like (carb free, note some K-cups and similar knock-offs have sugar added
*** I use Kerrygold unsalted, most Walmarts sell it
**** Do your own research here, I use Liquid Coconut Oil by BetterBodyFoods, sold in my local Walmart as it claims 78% MCTs and, the way this stuff makes me feel, I believe them. It's about eight dollars a bottle, but will last for quite a while (one lasts me 2-3 weeks and I make my coffee twice a day plus cook with this oil.)
