Kathrine before
In 2002, Kathrine Lee showed off her 175-pound weight loss on Oprah's stage. Proud of her hard work, Kathrine thought her weight struggles were gone for good. "I would have sworn on a Bible that I had it together," she says. "I thought: 'There's no way I will ever go back to being the way I was before. Ever."

Kathrine had kept the weight off for seven years, but after she met her future husband, she says the pounds began creeping back. "When love came in my life again, I got on birth control when we got married and gained 20 pounds. I had never had a chemical weight gain," she says. "Then I got off birth control and got pregnant, and then I gained more weight."
