I did this diet back in 07. I've never been sicker in my life. A lot of the foods recommended in these don't eat meat diets actively lower testosterone, which as a man, is bad for me.
I'll stick to healthy saturated fats, nutrient rich meats, sensible amounts of veggie sides, with the occasional potato dish or rice bowl. Essentially the PHD.

I just don't trust those guys from CSPI.
