Last year, Karen wrote to The Oprah Show to stage an intervention for her overweight husband, Jason.

"I eat a lot of candy at night trying to keep awake 14 hours at a time," Jason said. "I feel like a 45, 50-year-old man in a 30-year-old body."

Jason also had a snoring problem so severe that it worried Karen. "It sounds like he's gasping, that he's actually not breathing for a couple seconds at a time, and I can't imagine what that might be doing to his heart," Karen said.
