I just use "eating like you're poor" because that's how it's described in the book. As it is the way I've been eating for about 6 months is fairly close to this, I eat less than 8 ounces of super lean meat a day, and get most of my carbs from whole grains, vegetables, and fruit. The only massive difference is that this will add a bit more fiber, probably cut a bit of protein from foods (I'll be supplementing protein so I make sure I get enough), and it will probably add more carbs. The goal here isn't for it to be a permanent change to eating a meat free diet, but more of an experiment to see if I see a noticeable difference in energy levels like the author claims.

I really wouldn't call it a fad diet, because to me a fad diet is something like the grapefruit diet, or something like that. Done the right way this is a way one can realistically eat for the rest of their life and do so healthily.
