"I'm still on [the Weight Watchers eating plan]. I'm counting the points every day and slowly it's happening," said Winfrey, a Weight Watchers spokesperson, in an interview with ET's Nischelle Turner at the Essence Festival in New Orleans on Saturday. "I love it."

For the 62-year-old media icon, losing weight and keeping on her meal plan is motivated by seeing a noticeable change with her body. She also revealed that she’s not looking to reach her goal by looking at a scale.

"It's a feeling where you get to the point where [you think], 'Oh I can go to the store, I can pick that size, it's available, I don't have to like have it altered and all that stuff.' So I'll know when I'm there," she shared.

"I never wanted to be the person for whom people were saying, 'Oh that show was so good two years ago.' I never wanted to be the person who [was told], 'You should've gotten out of the ring before you got punched stronger,'" Winfrey shared. "I never wanted to be the person who didn't know when to exit the party."

"It was the most glorious, most amazing platform anybody can have to speak to millions of people every day and I think I exited in the exact right moment," she continued. "Sonow I get to tell stories in a different way."
