When fans of My 600-lb Life tune in, they expect to catch a glimpse of a jaw-dropping life transformation. But once in a while, the patients on the show throw everyone a curveball. From picking fights with show physician Dr. Now to sneaking pizza into the hospital, here are the 600-lb Life stars who rubbed us the wrong way.

Penny Saeger appeared on My 600-lb Life Season 2, rendering her one of the reality show's O.G.s.

But unlike her fellow co-stars that season, Saeger didn't comply with Dr. Now's diet and exercise plan. Although she did drop 40 pounds while hospitalized at the beginning of her episode, which qualified her for weight loss surgery, those pounds weren't lost for long. She even managed to gain weight after surgery.

Things didn't exactly improve in her follow-up episode, either, in which Saeger claimed she was doing much better and seeing improvements in her health. Of course, Dr. Now didn't agree, explaining that Saeger is addicted to food and is also delusional about any so-called progress.

As for where Saeger is now, Starcasm reported that she keeps a low social media profile, and that her photos show no transformation. Keep watching to learn about more My 600-lb Life Stars Who Rubbed Us The Wrong Way!
