I honestly don't understand what it could possibly have to do with obesity or aiding obesity.  It's pretty simple really. The people who came up with this as a treatment for IBS and C. diff and so forth were bullshitting when one said to another, "Fat people will eat anything, right?"  A bet was made and laughs were had and now there will be a line of scootypuffs full of fat fucks leading to the pharmacy, waiting for the incredible privilege of paying to eat our shit.
