This. I'm thinking like the old speech "Ain't I a Woman?"  Recast it for fat people. It will be perfect because you can start the speech like she did, about fat being a social thingiemabobbie, and then the part about all your friends dying of heart attacks, but aren't we (fat) people? The professor will buy into what it thinks you're saying, but it's only hearing what it wants to hear.  Even better, add in enough articles to make it sound scientific. Include many of The One True Book's references.
