TMI !!!! (too much information!)
If this person is 400-500 lbs, they need some kind of professional diet help.
Probably you're not familiar with the gigantic primitive yet, sir.
The gigantic primitive used to deal cards in a casino in Last Vegas, one of the fringe benefits being that while dealing, he got all the chow he wanted, from the casino kitchen.
Over a few years, he widely expanded.
Well, he got to where he couldn't deal cards any more--one assumes because his belly interfered with his hands reaching the table--and so got laid off. This put him into a funk, and he chowed down even more.
The gigantic primitive is married to a long-suffering woman who supports both of them on her meagre wages in telemarketing. There's a roommate too, male, middle-aged (the gigantic primitive is 40 years old), apparently chunky also.
Some months ago, the gigantic primitive got on our backs, being awarded social security disability. So he's not only a burden to his wife, but to the rest of us, living the life of Reilly while we sweat and toil and labor.
I really want the gigantic primitive to succeed, to get his weight down to 400 pounds, so he can go out and get a job, so as to ameliorate the burden on his wife--and the rest of us--but it seems the gigantic primitive's hit some sort of plateau where he's stopped losing weight of any significance, perhaps subconsciously realizing that if he succeeds, he'll have to go to work.
The gigantic primitive was first spotted on Skins's island, but moved to this other web-site because he thought the primitives were "insensitive" to the trials and tribulations of grossly fat people.
