Agreed 1000x. There are some completely questionable pieces of advice in the book and Tim Ferris is kinda sketchy, but the major message is not "here's a diet you should do" it's "you should experiment, here are a few of the vectors and here's what I did - try it, and then try some other things." The strategies are suspect, but he does a great job laying out the moving parts.
