At recent events to promote a new film she is coproducing, The Color Purple, Oprah Winfrey hit the red carpet in skintight purple dresses that showcased her dramatically slimmed-down figure.

Oprah, 69, shared her weight loss tactics in an interview with People on December 14. Her big reveal: She is taking prescription weight loss medication for the first time.

“The fact that there’s a medically approved prescription for managing weight and staying healthier, in my lifetime, feels like relief, like redemption, like a gift, and not something to hide behind and once again be ridiculed for,” Winfrey said in the interview. “I’m absolutely done with the shaming from other people and particularly myself.”
