I haven’t read “Keto Clarity”, but really learned a lot from the other three.
I’d also add Taubes’ other book, “Why We Get Fat: And What to Do About It” for people who want the Cliff’s Notes version of the history of/context for why conventional nutritional recommendations are what they are, and what the data instead actually show is good for our bodies.
There’s a lot of value in Robert Lustig’s “Fat Chance”, too, though he falls short of recommending a ketogenic diet, focusing on how cutting sugar and highly-processed, unnaturally shelf-stable food out of your diet can improve your overall health. I think this book is actually a great example of how, even in the face of overwhelming evidence (Lustig treats obese children), it can be incredibly hard for people in the medical professions to recommend a low carb, high fat diet. Lustig is really detailed in the case he makes against sugar and processed foods, but can’t extend that logic to, say, potatoes, which are highly insulinogenic.
