Very impressive physical changes, but even more so the changes in their personalities.

Christina especially, was a passive, lifeless whiner.  Suddenly she is proactive, invested in her well-being, and loving life again.  It's nothing short of a miracle.  WOW.

Unexpected was how the weight loss laid bare the fetishist nature of some of the caregivers' dysfunction, Sadly it was truly a fetish and there was nothing else.  The obese persons found health, but the caregivers are still sick.  Kudos to Christina's mother for changing her outlook from enabler to supporter.  Very impressive.
