It’s been ages since I’ve posted what I would call a “real” blog post. Something meaty and educational. Something you can really sink your teeth into. The last one was way back in August, when I wrote about . (Hint: it’s not.) I’ve posted a few things since then, but nothing all that substantial. I’m glad to say today’s post makes up for lost time, because it is LONG. So grab yourself a cup of coffee or tea ( ), put your phone on silent, and dig in.
I’m excited to share this with you. So excited, in fact, that I’ve been procrastinating on writing this for no less than 6 months. In looking at the folder of blog post drafts on my computer, I started jotting down notes for this in July 2018. The reason I kept putting it off is that I knew this was going to be a LONG post—massively long, even for me. But then I gave a talk on this topic at in December, so I finally had to organize my thoughts and put them together coherently. Once that was done, I figured it would be easier to get this written, since I could just flesh out the details of what was on the slides. Don’t kid yourselves, though. This still took four days to write and edit. (It’s much faster to talk and show images on slides than it is to type everything out in detail in a blog post!) Nevertheless, I’ve wanted to write this for a long time, so here we finally are. And the benefits a blog post has over a talk is that you can read this at your leisure, click on whatever links you’d like to explore further, and go as deeply down any of those rabbit holes as your heart desires. And to any of you who are happy at such a long post and who prefer reading to watching videos, I’m with you. to bring my message of Keto Without the Crazy™ to a wider audience, but I, myself, prefer reading.
One of the things I love most about writing my blog is sharing with you, my beloved readers, the fascinating and important things I learn as I deepen my understanding of human metabolism and physiology. The reason they call it “commencement” when you graduate with a degree in something is that it’s the start of your education, rather than the end of it. This has certainly proven true for me since getting my M.S. in nutrition.
One of the most intriguing things I’ve come across recently is the concept of the personal fat threshold. I don’t know who first coined this term, but it appears to have been Roy Taylor and Rury Holman, in their 2015 paper, . Other researchers wrote about the concept long before this paper, but I think Taylor & Holman were the first to use the phrase personal fat threshold. (Their paper is the first place I ever saw it in print, anyway. A researcher named Keith Frayn wrote some outstanding papers on the same topic years before without using the term. I cite his work liberally throughout this post. If you’d like to read the full text of any of the key papers I cite here, feel free to email me and I’ll send you a copy.)
