I started doing it when the Bulletproof coffee guy first came on the Rogan podcast, so pushing two years now.
First off that guy has been exposed as a fraud by Rogan and others with regards to his talks on high mycotoxins levels in coffee and his magical coffee beans that are toxin free.
However he did make the Bulletproof coffee recipe popular, which originally came from Robert Wolf, the paleo guy.
It does help fill you up a little bit in the morning, is it a magical drink? Not by any means.
I wouldn’t drink it if I wasn’t as active as I am, but I stand most of the day at my workstation, lift weights four-five days a week program depending, weight vest walk four days a week (walk the dog every day it isn't raining 1.5 miles) and hill sprint one-two days a week. So I’m always ****ing hungry.
I do one small tablespoon of Kerry Gold butter, same amount of MCT oil, packet of stevia, and a tablespoon of this hippie organic sugar free chocolate powder. This is for 16oz of coffee. I blend it all with a hand blender in a large pyrex four cup bowel. Its actually pretty delicious, but JUST the butter, MCT oil, and coffee, its kinda meh.
