Why is obesity a reason to deny whole body donation and what are the actual parameters? Seems like, with so many larger bodies, they'd like a variety. Shipping a 500lb body may be more problematic than a 200lb body but I'm sure there are things to be learned from both. In my case, they could figure out why all my tendons are sprung and how the damned arthritis progressed. In another friends' body there's a "history of dental work" to compare.
