I bought this book without thinking. I so enjoyed The 4-Hour Workweek I was ready to buy any book by Tim Ferris. But the "4 hour body" over reports of a collection of "tips" a little delusional about everything and anything about the human body. It is a sort of "guide hacking" not very convincing biological rather difficult to navigate: very disjointed, chapters mix personal stories, other people stories, controversial scientific results ... To choose, better browse the blog Tim on the subject.
