I drink a concoction loosely based on Bulletproof Coffee almost everyday and have been following a mostly Paleo Diet for over half a year now. I don't want to oversell it, but these kinds of dietary changes have been extremely valuable to me. I originally planned to run a series of about 3-5 diet experiments, but I had so much improvement on the first one I tried, I just stuck with it and made it a life-style change (although, I still make minor tweaks here and there). I made much of my data publicly available here. Let me know if you have any questions.
Tell me more about your concoction. At the moment I drink one of these every morning as the best balance I've found between being palatable and having high protein and low carbs but am thinking about changing. I'm lactose intolerant so I don't know if I can follow the butter advice but MCT might have potential.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
