Stacey Halprin's Weight Loss Journey

By Stacey's ninth appearance on The Oprah Show on May 2, 2007, she had become one of the most talked-about guests in our 25-year history—and had become an author. Her book, Winning After Losing, chronicled her struggle to keep off the pounds. "I'm proud of it because it tells you, 'Okay, you're here. How do you stay here?'" she said.

In her book, Stacey shared a weight loss secret that helped her keep the weight off over the past several years: If she had a momentary weakness at a buffet or happened to binge on Oreos in the afternoon, she didn't let the setback spiral into more than a temporary lapse. "Normal people gain 10 and 20 pounds. It doesn't mean they have to keep going," she explained. "What the winners do is they go to the exact next meal and they start like it never happened."
