Interesting books?

Hi all,

Out of interest, has anyone had any experience of this book?

https://www.amazon.com/Ketogenic-Diet-Comprehensive-Weight-ketogenic-ebook/dp/B07L3Y9M87/ref=sr_1_41?s=digital-text&ie=UTF8&qid=1544098862&sr=1-41&keywords=ketogenic+diet

I'm tempted to get it because it's free at the moment, though I'd rather pay for a book if the content is better.

If not, can anyone recommend any better books for a beginner?

Thanks very much for your help!
