Amazon shows a few books with the title keto clarity. But I'm guessing it is this one Keto Clarity: Your Definitive Guide to the Benefits of a Low-Carb, High-Fat Diet https://www.amazon.com/dp/B00MEX9B4C/ref=cm_sw_r_cp_apa_5tIUzbM9W12M9
Thanks for the reading material. I plan on doing more research before starting. I did look in /r/keto but I'll look at the other too. Thanks.
