Weight loss has always been a hot topic on The Oprah Show. "It's hard to throw me a curveball when it comes to this topic," she says. "But I have to say, in all my years, I've never heard a weight loss story as dramatic, traumatic and sad as this one." 

During his lifetime, Michael Hebranko has gained and lost over 3,000 pounds. At 34, he reached his heaviest weight: 1,100 pounds. "I have eaten 24 pork chops, 2 pounds of bacon, three dozen eggs at one sitting," he says.

Michael says he reached rock bottom when he lost his will to live. "I put the gun in my mouth; I went to pull the trigger," he says. But Michael didn't go through with it—instead, he wrote a letter to weight loss personality Richard Simmons.
