I think The Peat Whisperer comes pretty close to this. It does have a lot of "Peat-theory" in it; it's not a diet book that you could just toss at an uninterested friend or relative. But I think it has to build that minimum level of understanding before looking at Peat's context-dependent recommendations.
Once you have the theory down, it's very actionable: principles for choosing foods, what to do for particular labwork results, meal suggestions, supplements, etc.
Also, I don't think Danny Roddy "deviates" the way some people perceive. In the book, especially, pretty much every other sentence has direct references to Peat's articles, interviews, etc.
