Seems a good book for starting out. Dos and don'ts clearly set out without too much waffle. Little niggle, the recipes are all in ounces and lbs. I know this is written by an American but the most of the world uses grams, so maybe both measurements could have been given?
This is more like pamphlet than a book. I really did not learn anything that I had not already read free online about ketosis. There a few recipes I may try.
Appalling grammar - I don't think the author is a native English speaker. Too much repetition - padding? I wouldn't recommend this book unless you want the recipes.
