No, I'm pretty sure Al is NOT primal. There are quite a few hints in the Today Show story that point to him not being Primal:
- No Primal would stay on gluten-free sugar free only for a "28-day detox." For us, that detox is forever.
- No Primal struggles with keeping the weight off, as Al says he does.
- Look at Al jogging in the t-shirt. Rolls of fat! Probably 45 pounds worth. After four years, I believe a Primal would have done better.
- No Primal would have stopped to write a book about weight loss while he still had 45-50 extra pounds to lose. Al probably thinks he is done; a Primal would have kept going.
- A Primal would have shouted his diet from the rooftops, almost proselytizing... come on, admit it, we've all done it. But Al never said Primal or Paleo or Caveman.
- Nobody on the Today Show accused him of being nuts. That alone is proof.
I looked up reviews of Al's book on Amazon. There are only 11 reviews so far, but all of the reviews are about "inspiration" and "recharge your willpower" and other CW diet psychobabble. Not one of the reviews mentions Paleo or Primal. If Al were Primal, it would have shown up in the reviews.
If I were to guess, I would say that Al's diet is the usual version of Moderation Healthy CW. I would also guess that Al is at the "Insidious Weight Gain" point on Mark's Carbohydrate Curve. Enough that he won't balloon, but enough that he'll never lose those last pounds.
