The book has some good info. Mark lead the pack with this nutrition info, some of the stuff catching on today (2019) I know he was pushing a decade ago. The book is a little obnoxious and reads more like a trend pushing magazine. Lots of photos of old dudes with their shirts off! I learned some good info but the book didn't quite live up to expectations. Mark's blog is more scholarly/academic sounding and less energetic. Its also not very concise and repeats itself often.
