Thanks for posting, I can't wait to check this out. I first heard about Dr. Kruse from a local guy who owns an organic juice bar. I was into juicing at the time (before I learned about keto) and he was telling me how he became interested in health. Essentially, his best friend did some extensive juice fasting and cured himself of cancer. I asked him for pointers on top of what I was doing and he said to add garlic and use a cleanse from Dr. Kruse. He couldn't say enough good about Dr. Kruse.
I just finished "Fat for fuel" by Dr. Mercola which I think you might enjoy. He takes keto to another level and essentially tells you how this way of life impacts you at the cellular level. He calls it "metabolic mitochondrial therapy". I enjoyed it because I really wanted to know the benefits of keto aside from weight loss. And it's really nice to see people emphasizing using quality foods and why that matters. I'm hearing about a lot of people lately who are using cheap tricks to go into ketosis and drop a few pounds, but those people in my opinion are missing the point.
Anyway, good luck. Sciency books can be doable if well written. Dr Mercola does well. Also, I found primal fat burner by Nora Gedgaudas to be a great read on the subject.
