TLC's My 600-lb. Life shows its subjects at critical stages of obesity, but mercifully, it seems like only two of the show's stars have died. And we just witnessed one of those sad endings on the reality show: Robert Buchel died on Nov. 15, with his episode airing posthumously on Feb. 28.

In five months, this man from Forked River, NJ, lost 340 of his 840 pounds, Starcasm reports, but he developed a painkiller addiction following a lymphedema excision. And in November, as he filmed his episode, Robert suffered a fatal heart attack.

"I lost my best friend and the person I was supposed to spend the rest of my life with," fiancé Kathryn Lemanski said on the show. "He told me, 'I don't think I'll make it through the night. I love you and I always will.'"

In a Facebook post, Kathryn added, "The only consolation I have right now is that we were together and that his last words of peace to me were how he felt about me and how I felt about him."

If you're interested in supporting Kathryn, there's a GoFundMe campaign to cover Robert's medical bills and funeral expenses.

The only other My 600-lb. Life death we've encountered was that of Season 1 star Henry Foots. As we saw on the show, Henry lost 275 pounds, nearly half of his body weight, in his quest to lose weight for his high school reunion.

Henry had actually died once before — during a procedure to remove excess skin, as Screen Rant reports — but his doctors revived him. "There was the light to take me to heaven," he later told TLC. "I wasn't ready for it because there's so much here on earth I haven't [done] yet."

But on May 16, 2013, nearly a year and a half after his episode aired, Henry passed away. Dozens of fans signed his guestbook on Legacy.com. "I just watched Henry's story, and it's evident he was a beautiful person," one viewer wrote. "I'm happy he found happiness and got to live his dreams before departing this life."
