Other than sports and a few other documentary programs, two of my guilty pleasures when it comes to TV shows (because most of the network stuff is crap, most of the cable news is biased, and all of the reality shows are scripted drama) are Hoarders and My 600 Pound Life.
I'm no psychologist, but I find the psychological issues of the people featured on those two shows absolutely fascinating. Nobody would choose to live like that (I'm talking about both living in filth with deep attachment to useless trash and eating oneself to morbid obesity to the point of death) without some sort of deep seated trauma/drama.
The train wreck episodes of both shows can be infuriating and heart breaking, but the success stories are very uplifting.
I am both a bit of a pack rat and I've struggled with trying to drop about 20 extra pounds on my mid-section that will not go away. Neither issue has a severe impact on my life or health and I don't obsess over my possessions or my desire for unhealthy food. But in a non-extreme case, I loosely identify and sympathize with the show subjects who are not complete A-holes.
