Wow. Take one look at Mark and compare him to the interviewer. Now listen to each of them. Mark sounds bright and energetic whereas the interviewer looks like he just finished a 4000 cal Thanksgiving dinner and is having trouble keeping his eyes open. How can anyone think Mark comes off looking bad?
I did like Dr. Hyman's point that gluten free junk food is still junk food. It seems we try so hard to replicate junk food, whether low carb, paleo or gluten free, rather than just eating real food. This took me some time to learn as well.
