Definitely. However, that doesn't mean he is wrong. For more actual evidence of this stuff, The Eades' book `Protein Power'[1] and Robb Wolf's book `The Paleo Solution'[2] offer some pretty compelling evidence of how grains and related foods are detrimental to our health (among other topics). I, too, am a Paleo success story, having gone from 210 to 185 in 2 months, and feeling better than I have ever felt. All I have is anecdotal evidence for myself, though, so I always refer others to these books.
