You know what,  i don't even give a toss about their health. So fucking over that.          There should be a cut-off point (the medical criteria for morbid obesity) at which the healthcare system / social welfare system should pull the plug on them. Entirely.  Either lose weight or die.       As it is now,  being overweight is just a passing, transitional phase to obesity > morbid obesity  (unlike a few decades ago when people more-or-less stuck with their adult weight without extreme fattening).   The prospect of zero medical assistance / welfare benefits might just be the right deterrent.        The nicey-nicey approach  does not work.  It's like piss in the Sahara.
