Interesting clips. I don't like that it's being marketed as "anti-Supersize me" because I don't feel like the information being presented in the clips I saw have to do with what Supersize Me talked about.
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
Pain is your companion, don't go hide from it."
