I need a South Park Style "accountabilibuddy"

Hello, other people reading this. It's about that time when I take a good look at myself in the mirror and shout "Obama!"
I'm up to 280lbs at 6', the heaviest I've ever been. I'm lookin to get down to 240lbs and I need a group of like-minded regulars to keep me focused instead of letting me chop my arms off to lose a solid 20lbs... (Or however much my arms weigh) I'm going with diet and regular runs/walks. It's nice to preemptively meet you!
