Query: Weird writing style akin to a tv infomercial

I picked up this book because the topics interested me -- health, nutrition, meditation, etc. All in all, however, it proved a dissatisfying read, and the few suggestions I tried (a few of the nutritional supplement recommendations) had unpleasant effects. The tone of the writing reminded me of a tv informercial. It mixes an odd zealotry for the author's lifestyle recommendation with the promotion of specific products, which made me wonder if she has some interest in seeing these products sold. Really, a book to avoid.
