The discussed book is NOT intended as just a "How To..".

I do get the objection -

The Art and Science of Low Carbohydrate Living: An Expert Guide to
Making the Life-Saving Benefits of Carbohydrate Restriction Sustainable
and Enjoyable [Paperback]
Stephen D. Phinney (Author), Jeff S. Volek (Author)

Making the benefits sutainable sounds like a how-to discussion to me
when I read the title of the book. That conflicts with the "not a how
to" bit in the description.

I own and have read their previous book. It was very good. Good enough
that I have added it to my Amazon wish list in spite of this
contradiction. I figure all books contain contradictions and errors
once you analyze them enough. It's the total content that matters as
long as the number of errors is small compared to the value of the
correct parts.
