She list the infamous " paddy wagon of fat " moment from her old talk show as an example .

Oprah Winfrey apologized for the part she played in promoting unhealthy and unrealistic diets.

Whilespeakingon Thursday’s WeightWatchers “Making the Shift" livestream,Oprahadmitted she’d been a “major” contributor to diet culture with the constant emphasis she placed on weight loss.

“I’ve been a steadfast participant in this diet culture,” Oprah said. “Through my platforms, through the magazine, through the talk show for 25 years and online.”

“I’ve been a major contributor to it,” she continued. “I cannot tell you how many weight loss shows and makeovers I have done, and they have been a staple since I’ve been working in television.”

Oprah said one of her “biggest regrets," specifically, is a 1998 episode ofThe Oprah Winfrey Showwhere she brought out 67 pounds of animal fat onstage to show what it looked like after she’d recently lost the same amount of weight.

“It sent a message that starving yourself with a liquid diet set a standard for people watching that I, nor anybody else, could uphold,” she recalled. “The very next day, I began to gain the weight back. Maya Angelou always said, ‘When you know better, you do better,’ so these conversations for me are an effort to do better.”

Oprah previouslytoldPeople that her regimen now includes, among other things, regular workouts and weight-loss medication, though she didn’t share which one.
